LAFmax – The maximum Sound Level with 'A' Frequency weighting and Fast Time weighting during the measurement period. LAFmin – The minimum Sound Level with 'A' Frequency weighting and Fast Time weighting during the measurement period.
What is L max for noise?
The LMAX, or Maximum Sound Level, descriptor is the highest sound level measured during a single noise event (such as a vehicle pass by), in which the sound level changes value as time goes on.
What is LA90 noise level?
LA1 represents the noise level exceeded for 1% of the measurement period; • LA10 represents the noise level exceeded for 10% of the measurement period; and • LA90 represents the noise level exceeded for 90% of the measurement period.
What is Lae noise?
LAE : A-weighted, sound exposure level. LAeq : A-weighted, equivalent continuous sound level. LAeq,T : A-weighted equivalent continuous sound level, T denotes the time period over which the fluctuating sound levels were averaged, for example LAeq,8h is the equivalent continuous noise level over an 8 hour period.
What does Leq stand for noise?
Equivalent Continuous Sound Level (Leq )
Leq (equivalent continuous sound level) is defined as the steady sound pressure level which, over a given period of time, has the same total energy as the actual fluctuating noise.
