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

Sound Intensity

Sound intensity is measured in Decibels (dB). This is a logarithmic scale in which an increase of 10 dB gives an apparent doubling of loudness.

Sound pitch is measured in Hertz (Hz), the standard unit for the measurement for frequency. The audible range of sound for humans is typically from 20 Hz to 20,000 Hz, although, through ageing and exposure to loud sounds the upper limit will generally decrease.
