Good Hearing?

A typical person with good hearing can hear from about 20Hz to 20kHz (the audio bandwidth). A person's voice will usually range from 500Hz to 2kHz.

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

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

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.
