Environmental Noise Levels
According to the National Institute for Occupational Safety and Health, the maximum exposure time at 85 dBA is eight hours.
At 110 dBA, the maximum exposure time is one minute and 29 seconds. If you must be exposed to noise, it is recommended that you limit the exposure time and/or wear hearing protection.
A three dBA increase doubles the amount of noise, and halves the recommended amount of exposure time.
Air Testing & Leakage
Air Pressure Testing is not just for new-builds, it can be used to find leakage areas in existing buildings, improve the air tightness and improve/stop drafts
Sound Absorption
The loss of sound energy when sound waves come into contact with an absorbent material such as ceilings, walls, floors and other objects.
