Acoustic

Noise sources cause changes in air pressure which are detected by our ears. These changes can also be measured by a sound level meter. The pressure changes are expressed in decibels, which is written as “dB”.

Noise can occur across a whole range of frequencies from low frequency rumbles to high frequency chirps. Measured noise levels include all frequencies, but as our hearing is less sensitive to lower frequencies, the measured levels are adjusted to correspond to human hearing. This adjustment is called “A weighting” and is identified by the letter A.

Noise levels fluctuate and therefore it is necessary to consider both average (LAeq) and maximum (LAmax) values. For construction noise, average values are assessed over a time period (t) between fifteen minutes and one hour, as appropriate to the particular activities

.

 The average and maximum levels are shown in the figure below. The LAeq(t) is obtained from an ‘energy’ average of the decibel values; this results in a higher average level than normal arithmetic averaging.
