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.

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.

Air Testing

As part of thermographic surveys we can also use an air Pressure testing kit to depressurise the building and help detect any air leakage within the property
