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 Absorption
The loss of sound energy when sound waves come into contact with an absorbent material such as ceilings, walls, floors and other objects.
How loud is too loud?
Continued exposure to noise above 85 dBA (adjusted decibels) over time will cause hearing loss. The volume (dBA) and the length of exposure to the sound will tell you how harmful the noise is.
In general, the louder the noise, the less time required before hearing loss will occur.
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.
