Common Sources of Hissing Noises in Buildings
Unfortunately lots of different things can produce hissing sounds.
Where to start: It makes sense to try to track the sound to its source, then look more closely.
Here are a examples common sources of of hissing noises heard indoors.
Hissing sounds at air conditioning compressors,
in some cases may be dangerous, especially if very loud, in other cases might be normal.
Hissing may be due to an internal relief valve, a refrigerant leak, or normal operation of an expansion valve.
Something as simple as a bad fan start capacitor might be at the root of hissing noises at a heat pump or air conditioner compressor. Hissing may also be traced to an air duct leak.
air escaping from the air volume control valve on some water pressure tanks, such as the U.S. Gauge Type 310WJ Air Volume Controls makes a hissing noise and is normal but should only occur on occasion, not constantly.
Otherwise there is a problem putting too much air into the water tank.
of water running in water pipes. If you hear a hissing noise only when running water in the building,
try first just slightly reducing the incoming water pressure or even more simple: just close the main water shutoff valve slightly to change the water flow rate through thge valve.
Can be caused by the heating of water in the tank.
see WATER HEATER NOISE DIAGNOSIS, CURE - identify and cure noises at water heaters such as rumbling, clanking, burbling, hissing, and clinking noises observed at water heaters.
Hissing sounds from a water leak -
such as a hole in a water supply pipe - you'll find this
can make people experience a hissing noise as well, such as tinnitis, other medical conditions, or in some cases psychosocially generated auditory sensation
Sizzling noises at a split system AC or heat pump
(which some may describe as hissing) from a split system air conditioner / heat pump may be heard at the wall mounted unit when the system is in heating mode. [10]
Electrical system hissing sounds:
Watch out: hissing or sizzling noises associated with electrical wiring, breakers, fuses, or equipment often indicate a dangerous overheating or short circuit hazard.
Shut such equipment down immediately and obtain help from a licensed electrician.
White noise generators, used in professional offices and by some others can produce a sound that some listeners describe as "hissing"

ASA is an excellent source of noise and sound standards. Quoting from the associations history page:
"From the Society's inception, its members have been involved in the development of acoustical standards concerned with terminology, measurement procedures, and criteria for determining the effects of noise and vibration. In 1932, The American National Standards Institute (ANSI), then called the American Standards Association, appointed the Acoustical Society as sponsor of a committee, designated as Z-24, to standardize acoustical terminology and measurements. The work of this committee expanded to such an extent that it was replaced in 1957 by three committees, S1 on Acoustics, S2 on Mechanical Shock and Vibration, and S3 on Bioacoustics, with a fourth, S12 on Noise, added in 1981. These four committees are each responsible for producing, developing a consensus for, and adopting standards in accordance with procedures approved by ANSI. Although these committees are independent of the Acoustical Society, the Society provide
s the financial support and an administrative Secretariat to facilitate their work. After a standard is adopted by one of these committees and approved by ANSI, the Secretariat arranges for its publication by ASA through the American Institute of Physics. The ASA also distributes ISO and IEC standards. Abstracts of standards and ordering information can be found online on the ASA Standards Page. More than 100 acoustical standards have been published in this way; a catalog is also available from the Standards Secretariat (631-390-0215; Fax: 631-390-0217). The Society also provides administrative support for several international standards committees and acts as the administrative Secretariat (on behalf of ANSI) for the International Technical Committee on Vibration and Shock (TC-108)." - http://asa.aip.org/history.html

Barrier Ultra-R super high-R building panels, produced by Glacier Bay, use Aerogel and are rated up to R-30 per inch, or in Barrier Ultra-r™ panels, R-50 per inch. The company also produces acoustic panels that are Ultra-db resistant and lightweight. Unlike the appliance insulation panels discussed in the original Q&A above on miracle insulation, these Areogel based panels will continue to retain some, though reduced insulating value if punctured, performing at perhaps R-9 per inch. The product is used in marine refrigerators, but in the future may be available as a residential construction product. The company is researching specialized products in medical, transportation, and aerospace applications.

Noise - a Health Problem - http://www.nonoise.org/library/epahlth/epahlth.htm - quoted below
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.
Protective Noise Levels - 1979, basis for many local noise ordinances and codes - http://www.nonoise.org/library/levels/levels.htm This publication is intended to complement the EPA's "Levels Document,"* the 1974 report examining levels of environmental noise necessary to protect public health and welfare. It interprets the contents of the Levels Document in less technical terms for people who wish to better understand the concepts presented there, and how the protective levels were identified. In that sense, this publication may serve as an introduction, or a supplement, to the Levels Document.
