Watch out : Always remain alert for a possible tapping noise that was not in the list.

"Inspecting to the checklist" is one of the most common mistakes made by amateur or high-speed inspectors. If you just look for what's on the list you risk missing what's actually important in the building.

Watch out : also, people describe sounds differently. One person's "tapping on the door" may be another's "rapping noise" and someone else's snapping or popping or crackling noise. At the end of this page we provide links to diagnostic articles for these similar terms or sounds.

Question: tapping noise in wall heard when going to sleep

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

Reply:

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.

Question: rain patter sound complaints at 50 year old house - tapping sound

Hello friends,

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!
