Questions about building noise control, tracking down wierd building sounds, soundproofing, or just diagnosing what the heck is making that sound?
This article series includes catalogs of types of building noises & sounds, common sources for each of these noises, & methods of sound or noise control in buildings during construction or as a building retrofit.
These discussions of finding and curing the source of noises at, in, or around buildings were posted originally at NOISE / SOUND DIAGNOSIS & CURE - topic home. Be sure to see the suggestions found there for diagnosing and stopping aggravating building noises.
I have a howling noise coming in my bedroom whenever it is windy weather. It is really awful at night when it gets really loud. Can anyone tell me how to fix this horrible sound problem? - Kate
Kate, please take a look at the articles on tracking down building noises beginning
at SOUND CONTROL in buildings where you will see a series of suggested places to look when tracking down annoying building noises
. In that article you'll find a section on identifying common sources
of WIND NOISES at BUILDINGS.
If that information leaves you with questions don't hesitate to ask and I'll research further and do my best to help.
Specifically about wind, we have traced house noises to loose shingles, roof openings, and even signs or other things hanging on the building. But take a look at our house noise articles.
We had our house stuccoed and a new roof installed this summer. Now there is vibration from the roof, about 20 dB inside and a little louder outside. It is on one side of the roof only and can be heard in all rooms on that side of the house.
I see a buckle between 2 shingles at the bottom edge but cannot detect movement in any shingles.
Current wind is about 20 mph with gusts at 30; temperature is about 40 degrees. Sound is present regardless of precipitation. - Harper Snapp
When I listen to it now, I notice that the sound resembles snoring. Earlier in the morning I thought perhaps it was somebody starting and restarting a motorcycle, maybe 1/8 to 1/4 mile away.
That's a remarkable house noise - snoring due to wind noise through roofing materials. The noise could also be roof-related but by other components such as wind blowing through a vent or across guy wires of an antenna or over a chimney.
If you trace the problem to roof shingles it may be that the self-sealing tab feature has not yet activated - the risk is shingle wind damage.
Inspect the roof and the house exterior for things that might be the noise source, and see if you can interfere with movement in each one individually. For example I've put bricks along a roof edge (with obvious safety warnings about falling bricks) to hold down suspected loose shingles to test for reduction in wind noise.
keep us posted. What you learn will help other readers.
Thanks. I have now read about the self-sealing tabs. There is one shingle at the bottom edge which is raised. I am guessing that would be because it is improperly installed. We have also discovered that the snoring sound and the idling-motorcycle sound are coming from different areas.
As soon as the rain stops I will try the brick trick and look at some other things. I had previously consider the soffit vents, but they haven't been altered or even removed. I will keep you posted.
i live in a new build , wooden framed house, that has a constant hum going round it. the housing association had sound recording equipment put in to monitor it, and this recorded a humming , but the source couldn't be detected, the ha decided not to investigate any further as it was not cost effective.
But i am going round the bend with this constant humming. No one else in my street is bothered by it, as they all live in busy households , so don't really hear it, but i live in a quiet house , and have an illness.
My hearing has been checked, and apparently i have very poor middle and higher hearing, and the clinic thinks my lower hearing is overcompensating for this.
but i think the wooden structure of my house is somehow amplifying the outside noises, possibly from my air source heating system , and all my neighbours ones, and and my house is acting like some kind of vacuum to it. I cant take much more of this constant noise, I am so tired and irritable - A Schulen
It sounds as if you want to take a dual approach: consulting with your physician or audiologist as well as having independent confirmation of the noise around your home.
There are quite a few potential sources of humming noises in buildings. Once any question about the role of your hearing has been sorted out and the humming noise independently confirmed, I'd start some detective work using the suggestions in the list above.
This is a bit long winded, I appreciate anyone who makes it through the first paragraph. I have a sound in my home that is driving me CRAZY!
Brief Background. I purchased a 50 year old home about 1 year ago. The home is a ranch style, with a basement. It is a typical A-Frame style that is "longer" than it is wider. There is a fireplace in the basement family room and one in the upstairs living room.
After living there about a month or so, I remember waking up to hearing the pitter-patter of rain on my roof and gutters. It had been a rainy couple of days and I embraced the sound of my new home. I woke up, looked out the window, and realized it was nothing but sunny skies. Once my ear "caught" this sound, I realized it was fairly constant, and it stuck.
The sound. This is hard to describe, but I will give a few examples. The pitter-patter of rain on a roof is a good description, because rain on a roof is constant, but not syncopated i.e. each drop is a little louder or softer but there is a consistent sound. It sounds like a very light tapping on PVC tubing or thin wall conduit. If the audible thresh-hold of sound is 3.0db, these vary around 3.0 to 3.1.
It seems to be non-stop, year long, weather unrelated.
What I've done. I turned off the Main Electrical Circuit Breaker and turned off the gas going to my hot water heater, and I could very clearly hear the noise.
My problem. It seems like it is coming from the attic, but when I go into the attic, it seems like it is coming from the west side, but when I get to the west side, it sounds like it is coming from the east side. I can hear this noise anywhere in the basement, or anywhere on the main floor, but it seems more pronounced on one side of the house, which is the side of the house with the chimneys.
I've stuck my head in the chimneys, but can't make heads or tails of it, I actually can't hear anything in the chimneys. I've stuck my ear up to the attic vents, but hear mostly ambient noise. I've checked the gutters, the chimney caps, and each and every piece of conduit/plumbing running thru-out this house for loose or noisy connections.
There is also an Air Conditioning Unit in the attic. I have adjusted, padded and checked every piece of A.C. tubing related to that. No issues. There is also all the A.C. duct work that runs through the attic. I've inspected all mounting brackets and again, placed my ear directly to the ducts, but cannot hear anything. I've yet to find the source.
It's a shame that I finally moved out of the door-slamming, car-alarming, domestic-dispute ridden apartment complex I had lived in, only to long for simple silence.
Any ideas? They will be most appreciated.
If I ever find a solution, I will surely post it!
The french doors in my bedroom (to the lanai) "pop", both day and night.
The popping is so loud at night that it wakes me up. I don't know if it's the wood or the windows. They pop when the AC goes on or off, when someone opens a door, or most of the time for no reason at all that I can hear. Any ideas of how I can fix this ??? I'm becoming sleep deprived !!! - Sue Newton
Popping French Doors - sounds as if there is a thermal expansion and contraction source of noise.
Check the door hinges, air seals, and mount to be sure they are secure and that the door latches firmly. If that makes no difference, I'd give the manufacturer a call and ask for their help. Keep us posted -what you learn may help other readers.
I have a 60 year old home with a fairly new 95% efficiency Amana gas furnace in the basement. The exhaust pipe is PVC and runs across the basement ceiling, vented to the outside of the house above ground level. As the furnace heats up, there is a clicking or dripping noise from the PVC.
If I give it a tap with a stick, it stops. I have noticed moisture droplets off the coupling when I tap it. If I just let it alone, after 7-8 minutes the clicking stops on its own. Is it condensate heating up/moving/evaporating? It's extremely irritating because that exhaust pvc runs under my bedroom floor and I'd appreciate any tips on how to stop the noise. THANKS! - Lisa P
Watch out: dripping backwards in a high efficiency gas furnace vent system may mean that the vent is improperly installed or pitched. If condensate is not being properly drained and disposed-of the risk is that the heater may be damaged or even unsafe. I'd ask your local heating service tech to check out the venting and condensate drainage in your heater.

An unbearable humming noise has been emitting from our backyard neighbor's wall for several weeks now. They have a pool and a spa so I suspect the noise is a pump of some kind. It is constant, never stops, and, though it isn't unbearable outside, the noise filters into our attic and becomes amplified.
It makes our entire house "hum." We are thinking of breaking our lease and moving, it's become so unbearable. We can't sleep and we're starting to feel physical effects from the continuous noise.
We've enlisted the help of our HOA but so far, nothing has changed. And we have been unable to speak directly with our neighbors. Is there anything I can do to mitigate the sound on my end? We've tried a white noise machine, music, earplugs. NOTHING helps. - Sophie D 1/8/2012
some noise abatement possibilities - all the reasonable ones - begin with the question of whether or not your neighbor will respond without offense to a request to look into your noise complaint.
- the humming noise, if it's coming from neighbor's pool equipment, and if it has changed recently, can be a sign that a motor has a failing bearing and needs repair or replacement soon. Better sooner than later as an overheated motor might be unsafe too.
- if the pool equipment is enclosed, sound insulation in the enclosure can significantly reduce the noise transmission out
- I would not close off your attic vents - that's likely to cause other building problems.
Reader follow up:
We finally got together with the neighbors to try and troubleshoot this noise, which they've also been hearing. It's not the pool pump, although it is clearly on its last legs and was adding to the noise. They've turned it off until it can be repaired.
The power company came out and changed a noisy transformer in the neighbor's yard but that wasn't the source. We can't locate the noise. It sounds like the motor of a large truck idling right out front. Only it is constant, day and night. I'm at a loss for a solution. Who would be an expert in this kind of thing? A home inspector or an electrician or some other tradesman? Thanks again!
You might want to try buying a low-cost directional sound amplifier and ear-buds from Radio Shack or a similar supplier, along with a mechanic's stethoscope.
The sound amplifier can help you be more clear about the direction from which an outdoor noise is emanating, and the mechanic's stethoscope can confirm sound or noise from or at a specific piece of equipment. Some home inspectors and some hygienists have sound measuring equipment (see the EXPERTS DIRECTORY at page top)
Also look around the neighborhood for generator motors, garages, places where a motor or generator or even a wind generator is running.
I have tracked noises to sewer lines in the street, transmitted from several blocks away using this method.

HI there, my boyfriend and I live in a house that has a wood-burning stove as its source of heat. But whenever we start up a fire, which causes the metal stove to go from cold to hot, there is a loud bang when it heats up once the fire is going well. Any ideas on what that could be? Any help would be appreciated! - Jason & Ali 5/4/12
Watch out: what you describe could be dangerous. It sounds as if you are describing a noise produced by expanding metal that is at once trying to expand and is held tightly in place until the thermal expansion force takes over the restricting force.
Some such noises are harmless, but if there is flexing in the chimney or in woodstove parts there could be a risk of hidden damage that could result in a spark, heat, or gases leaking into the building - thus a potential fire or CO risk. I'd ask a certified chimney sweep, woodstove installer, or fire inspector for a safety inspection before continuing to use such a heating system.
For years its been happening when I lay down to sleep within a few minutes I hear a faint tapping/pop sound coming from the same spot within the wall that repeats every 1,2,5 or 10 minutes for the next 40 or 60 minutes but them completely stops.
What makes this very odd is this repeated sound only occurs 1 or 2 minutes after I lay down to sleep anytime between 11pm to 2am but never occurs any other time including if I lay down in the daytime or night, only when I go to sleep at night it will occur and almost every single night. WHAT COULD BE THE CAUSE? - Domenic R 3/16/12
Domenic, cooling house parts can make a noise that sounds like tapping or popping. Often these noises are present before going to sleep, but because we're moving around and making noise ourselves, we don't hear them until we lie quietly in bed.
We live in a 3rd floor maisonette with a flat roof and the home is at the top of a steep hill. In the last few years the landlord extended and fitted out the offices beneath us into residential flats. Shortly afterwards we started hearing a hum which starts off quietly and then gradually intensifies in volume until it stops.
This noise starts in even a slight breeze but depends on the wind coming from either an east or westerly direction. I can describe it as "mmm" "mmm" "mmm" and is loud enough to cover daytime conversation, and keep you awake at night. Have you any suggestions as to what it could be? - DP 5/26/12
DP if the hum is correlated with wind I'd start looking at all building surfaces, roof, walls, for a possible source of wind noise. Also it may be diagnostic to make yourself a list of all changes to the building - topics to investigate.
We have just moved into a 40 year old home in Texas. The house makes popping noises in every room day and night. I believed the sounds to be coming from the attic but when I investigated, I couldn't hear the noises.
Then I decided that the popping noises were coming from the walls and ceiling and believe most pops are near the top of the wall - but not always. The pops are always a single pop and vary in intensity.
Sometimes it is a very soft sound and other times it is loud enough to wake us. In one room, the popping noise sometimes includes a sound of falling metal. In most rooms, every wall is involved. Now that I have heard the popping noise for several weeks, I find that I can also hear it from outside of our home. The structure is brick on slab foundation. The roof is a hip structure with ridge venting. The attic is well insulated.
A builder friend of our realtor inspected the return vents, roof venting and the attic and found nothing wrong. He could offer no suggestions as to the source or what to do about it. Of course, the seller denies any knowledge of the noise so we have no way of knowing if they have had anyone look at it to rule out sources.
It is difficult to tell if weather is a factor. It is very hot here but I can't tell that the popping noise is any better or worse in early morning or late afternoon. It is very irritating to have spent our life's savings for our retirement home to end up with this. We live in a small town so "experts" in any field that might help us are far and few between. We really don't know where to start. - Judy 8/1/12
Judy, Popping noises that are all over the place and continuous day and night sound very strange to me - an immediate explanation does not suggest itself in those conditions; I'd track down the sound to more of a pinpoint location, using a mechanic's stethoscope if necessary.
I'd also like to know how the house is built - metal studs or wood framing - and to what activities or events we can relate the sounds: thermal changes, equipment turning on or off, air movement, people movement, sunlight exposure, etc.
Because you indicate that the sounds are continuous day and night one tends not to suspect weather, sun, outdoor temperature changes - look for something that is ongoing.
In such a mystery, the most productive course is pinpointing the sound source.
About the beginning of the summer our Victorian house started making a snoring noise (a guess is below 45 db) intermittently day and night. The sound is most noticeable from the dormer bedroom in the attic but can also be heard from the living room underneath the dormer room.
At first we thought it was a motor of some sort but we've ruled out my mother-in-law sewing in the room below the living room and the solar-powered attic exhaust fan motor (roofer said it only operates during the day). Because of the lack of street noise, the sound seems much louder at night and is quite a nuisance. What is causing this noise? - Karen 9/22/12
With virtually no information about your entire home, offering an explicit answer to "What is causing this noise" would be silly.
Some effort to track down the sound to source is what's needed. Some solar devices include a rechargeable battery, so from your note, I'd start by disconnecting the fan entirely to be sure you can rule out that sound source.
Check out our sound diagnostic approach described
at How to Find the Source of Building Noises by Keeping an Event Log of which I summarize some ideas just below
Two general approaches to tracking down the source of noises in buildings include:
Snoring sounds in buildings, if not traced to a person like my uncle Sig Frucht, are often traced to something that is vibrating;
Our mystery noise sounds like someone dragging heavy furniture across a hardwood floor. It lasts two or three seconds, ten to thirty times a day. For a long time I thought it came from the basement, until I was down there when it happened.
Now I think it may be coming from the front of the house, where the water main enters the basement. Is that crazy? The noise does not seem to be related to water usage. Just bizarre. And it has gotten markedly worse over the last several months. I wish I knew who to call!
We also may have a chipmunk problem under our walkway which is in the general area of the noise. I can't think of a way they could be making it, though! Going crazy. - Amy 10/24/2012
First we can probably rule out a chipmunk as someone dragging heavy furniture across a floor, though I've indeed encountered some surprising cases of odd sounds traced to animals - a rolling rattling sound in an attic was traced to a raccoon who was enjoying batting christmas tree ornaments around on the attic floor.
Part of the difficulty in tracking down sounds in buildings is that they are often transmitted through the building from the actual source of the sound to some other location where they are heard - through solid walls, piping, ducts, framing members. Nevertheless, for a mysterious sound such as the dragging scraping you describe, since I don't have an obvious explanation to offer, you might:
I hear a tapping, fluttering and sometimes knocking noise coming from the wall in my bedroom which drives me crazy when trying to sleep. The noise only happens when the wind is blowing in a specific direction and there is a PVC plumbing vent stack that runs through the exterior wall where the noise is coming from.
I've already confirmed that the noise is not coming from an outside air exhaust fan cover from the adjacent bathroom. I had that problem in my previous house.
Anyway, what could the wind be blowing to make this noise in a plumbing vent stack? There aren't any moving parts in the stack; are there? Could it be that the pipe is loose in the wall and is being shifted slightly by the wind? I just hope there isn't a break somewhere in the pipe and it's dangling in the wall; however, I don't smell any sewer gas.
To troubleshoot if the problem is caused by wind going down inside the pipe or whether it's pushing the outside of the pipe;
I'm going to wait until it starts happening again, then cover the opening of the pipe to see if it stops. Either way, I'm not sure what to do next short of opening up the wall. What a big mess. Any suggestions? - B.B. 12/11/2012
In tracking down wind-related fluttering or tapping or knocking, because such sounds typically involve a moving part, I think you're on the right track to try some experiments such as temporarily covering a vent pipe, though I've not come across a tapping, rap-tap-tapping ever tapping at my plumbing vent since The Raven.
In addition to our wind noise track down suggestions in this article at WIND Noise and wind-caused noises, you might also check
In fact for each of the above, the next time you hear the wind-related tapping knocking fluttering noise, try turning on each bath vent fan (if you have such installed) and the clothes dryer to see if the pressure of outgoing air stops or changes the sound.
Also inspect outside for:

I am becoming very sleep deprived and am searching for answers
. I own a double wide mobile home and in my bedroom,where wall meets ceiling above my bed, there is a very loud (seems very loud as it happens in middle of night for several hours) ticking or slapping noise, intermittent noise. it seems to be worse in extreme cold, although it does happen in summer sometime. any advice is appreciated, thank you. - G.D. 12/27/12
Without an onsite inspection (not cost-justified) I can only give some general advice and offer a few guesses. It's possible that the sounds you hear are related to thermal expansion/contraction as various parts of the mobile home expand and contract along with changes in temperature or operating of the heating system.
When I am trying to track down the cause of a "mystery noise" I find it helpful to make note of every site condition I can think of or observe that might give me a track-down clue.
When we can relate the occurrence of a noise to building or site conditions such as the operation of mechanical systems, temperature changes, weather, movement of people in the building etc. we can usually find the noise source and then we will know how to cure it. Take a look at SOUND EVENT LOG - in the article above for some specific suggestions.
Is there an instrument available that could be used to locate sound source? The common mechanical stethoscope is not very effective in locating the constant 24 hr humming sound in my home. The sound is a droning 60 HZ constant, but there are other sources harmonizing with it. I managed to eliminate the sound sources one by one and I am now left with the last two major ones. I badly need some help because my health is starting to go. - C.M. 4/23/2013
I agree that a stethoscope is not where one would start in finding the source of a widespread building noise.
A mechanic's stethoscope is useful principally when one is checking specific machinery, surfaces, or objects for sound emanation. This tool does not quickly direct one to an area of a building when a noise is heard as ambient or widespread
. For moving from an ambient widespread noise to a source requires a combination of careful listening with methodological investigation such as keeping a noise-event log to relate sounds to changing conditions of time, weather, equipment in or out of operation, nearby activities, combined as well with visual inspection and occupant interviews.
Directional microphones are sold by a variety of vendors who supply some quite different models and technologies. But I'm not sure an affordable directional microphone will do a great job tracking down a building noise source.
I have not found good success at tracking down a "general" noise using pressure-gradient-type directional microphones - the common instrument used to pick up remote conversations or sounds. Since directional microphones pick up noise from any direction you can be fooled if a sound coming from direction A is bouncing off of a hard surface B at which you have aimed the device. 
In other words some skill and experience are needed to use such tools. soundonsound.com has an excellent, if technical, explanation of the types of microphone and their sensitivity to the actual direction of sound emanation.
My reading about directional mikes suggests that equipment is intended for the recording industry or for the hearing aid industry but not for sound localization.
Engineers use about six different methods to pinpoint the origin of sounds, procedures described by Mehdi Batel et als (2003) . Six approaches to noise localization used by acoustic experts include
These approaches were tested and described for industrial applications such as the automotive industry and it does not appear that these methods, including a relatively new beamforming microphone array methods, are being used in residential noise complaint applications. Some are quite costly, some are quite time-consuming to use. Beamforming for sound localization can examine large objects (a car in a wind tunnel, for example) and is a more rapid process that might work in or at buildings, particularly where we are less interested in the precise sound level and mostly interested in finding the sound source.
If you can find an engineer who has access to beamforming sound-localization equipment, and if her employment and equipment costs are justified by your local noise problem, that approach may be what you need.
But before trying that more sophisticated and costly approach, a thoughtful site interview, investigation, and some data logging can very often find the source of a building noise. Perhaps these items will help you
Keep us informed on what success you have, as that may assist other readers.

We also --like I seen posted, have a crackling crunching noise with our siding---and we did have it treated a couple times for ants :)--that is not the problem.... we live in a condo and it is just the outside wall that does get sun on and off---is there any like silicone spray that would make it slide easier so the noise would not be so loud? This is frustrating!!! and annoying!
Carol, silicone spray ought not harm vinyl siding; aluminum siding, or for that matter possibly vinyl too, might be discolored, however, if the siding surface is oxidized. Try first in an inconspicuous area.
I would look further to see if the siding is improperly nailed - too tightly, restricting movement.

I'm experiencing vibration and resonating noise in my house from an external source. Its like have tens units on my feet. The vibration wakes me up and then it and other noise sources keep me awake. There are several electro-mechanical sources (heat pumps, HVAC, and hot tubs) in my neighbourhood.
Where can I find someone to take measurements in my home for proof there is a problem? How can I determine where the source of the vibration is coming from? I just recently found a hot tub that isn't making much noise but is a likely source of vibration. So far if I complain to the owner of a particular noise source the reaction is 'its not my equipment'. How far can vibration travel through ground?
Ken, you might find help by calling on a professional home inspector (see EXPERTS DIRECTORY in the top of this page) discuss your concerns with the inspector and confirm that she/he has experience in this tpe of inspection.
Keeping a log of when noise is observed, what equipment is operating at the time, combined with tracking the noise to its source usually narrows down the cause and thus suggests a remedy.
We have a two-story adobe home, 30+ years old with a pueblo-style roof, vigas were used in the upstairs ceilings. Throughout the day the roof makes creaking, cracking noises. We believe it has to do with expansion/contraction (this is in Albuquerque where there's big swings in temp throughout the day) but wonder if anyone has a suggestion!
Thanks in advance for your answers!
Barbara and Gary
I don't have enough information to hazard a guess, and worse, I'm not sure what you mean buy "vigas" in ceilings. Perhaps some photos of the home from outside and ceiling inside would permit a comment beyond the obvious thermal effects. Use the CONTACT link to send us images.
We do offer diagnostics for roof noises - see

how or where would the sounds of beats,waves and drums come from. we just moved in to this place
Linda it's such a broad question with no information about the home, location, neighborhood, nearby noise sources and other important factors that I just don't know. You will want to combine an auditory inspection (walk around and listen for where sounds are loudest), a visual inspection, and perhaps the SOUND EVENT LOG document whose link you'll find at the top of this article.
That should help you track down the noise.

Someone who has it out for me is tormenting me with some sort of electrical signal directed at my house. They are able to cause a high pitched type hissing effect when ever my refrigerator compressor is running as well as my receiver for my dish network that is also hooked into my television even the swamp cooler fan motor is effected with a hissing sound.
They have been doing this to me for over 6 months. The noise is now constant and at night they increase the surge or something like a surge, it seems to come in short waves if you really listen. I cannot sleep without earplugs and even then I can still hear the high pitch through the earplugs. It truly is a tormenting effect on me. Is there any way I can filter or scramble this signal? Can anyone help me? \
Further to my last post -- I can verify that the noise does occur, so it's not tinnitus!
Let's start by suggesting that you discuss tinnitus or other possible medical factors with your doctor and with an audiologist. Keep us posted.

I hear (and feel) a large pipe vibration noise in my house once in a while...it feels like air in the pipes (but in a big pipe...) it happens sporadically, even at night when no toilets have been flushed, no sinks have been run. We have heard it approx 6 times over the last 4 months. It occurs only once, approx 5-10 seconds, then it goes away for a couple of weeks. We do not have a sum pump, and we are connected to a sewer system. It happens rain or shine. Any idea what it could be? I am worried sick I'll have to dig up under my house..
As we suggested at your other posting on another article, try turning off the water main to confirm that the noise is in the supply piping.
Try an electronic portable sound amplifier (Radio Shack) and a portable tape recorder.

Every time the AC comes on the drain pipe in the bathtub continually makes a hammer noise. Don't understand it. What to do?
JW that baffles me too. All I can guess is that there may be a depressurization of some areas of the home when the blower fan comes on. If the hammering noise is continuous I'd be looking at water supply piping troubles.

I have a question about a "popping, gunshot-like" noise that my tenant is reporting. We're both completely baffled by it! It occurs in the outside wall towards the floor in a first-floor flat. There doesn't appear to be anything tapping from the outside.
There is no radiator or pipes near that wall. The electrical socket has been ruled out as the cause and the noise continues when the electricity to the flat is turned off. The flat is in a quiet area of Cambridge, UK, not near roads. It occurs randomly throughout the day and night but sometimes it stops for a day or so. We lived in the flat for 10 years and never heard it.
Only two things have changed since we moved out: the tenants are using a 10-year-old cable broadband outlet on the wall that we haven't used for 5 years. However, the noise still occurs when this is unplugged. And we have had a carpet installed.
I know it sounds crazy, but could the nails keeping the carpet grippers attached to the concrete floor be the cause? I just can't think of anything else! There was a suggestion that the small electrical current that is in the cable broadband box could cause a popping, but we never heard the noise ourselves and, as I say, it still occurs when unplugged.
Thank you so much for any ideas -- we just don't know what to do and our tenants are going crazy over it!
Let's start by asking you to keep a SOUND EVENT LOG (see the link above)
with that we might correlate the sound to temperature swings, leading to a look for what might be expanding or contracting such as siding or piping

Some smoke or CO alarms will chirp just as you said - for battery; if it's still chirping after a new battery was inserted I'd replace the unit, figuring that the sensor is fouled.
If you're not sure that the noise is coming from the alarm, remove the alarm and place it far away and check again.
Remember to see if there is more than one CO or smoke detector alarm in your home - you may be checking the wrong one.

Racket, din, clamor, noise. Whatever you want to call it, unwanted sound is America's most widespread nuisance. But noise is more than just a nuisance. It constitutes a real and present danger to people's health. Day and night, at home, at work, and at play, noise can produce serious physical and psychological stress. No one is immune to this stress. Though we seem to adjust to noise by ignoring it, the ear, in fact, never closes and the body still responds - sometimes with extreme tension, as to a strange sound in the night.
The annoyance we feel when faced with noise is the most common outward symptom of the stress building up inside us. Indeed, because irritability is so apparent, legislators have made public annoyance the basis of many noise abatement programs. The more subtle and more serious health hazards associated with stress caused by noise traditionally have been given much less attention. Nonetheless, when we are annoyed or made irritable by noise, we should consider these symptoms fair warning that other things may be happening to us, some of which may be damaging to our health.
