omissions is welcome:

‘A’ weighted

decibel

Internationally accepted unit for most noise measurement and which

represents the sound pressure level weighted to correspond to the

frequency response of the human ear. A difference of 3dB(A) may

just be noticeable and a difference of 10dB(A) represents a doubling

or halving of subjective loudness.

site

Sites that contain the intermediate shafts from which the

LA10(T) The LA10 is the A-weighted sound level which is exceeded for one

tenth of a time period T. For example, the level which is exceeded for

a total of six minutes in an hour.

LA90(T) The LA90 is the A-weighted sound level which is exceeded for 90% of

a time period T.

LAeq(T) Equivalent continuous sound level is a notional steady sound level

which would cause the same A-weighted sound energy to be received

as that due to the actual and possibly fluctuating sound over a period

of time (T). It can also be used to relate periods of exposure and noise

level. Thus, for example, a halving or doubling of the period of

exposure is equivalent in sound energy to a decrease or increase of

3dB(A) in the sound level for the original period.

LAmax The maximum sound level measured on the A-weighted scale

occurring during an event.
