LAeq is presser level measurement parameter. Full form of LAeq is " Equivalent continuous A-weighted sound pressure level". It is widely used around the world as an index for noise. LAeq = 10*log[1/(t2-t1) * Integration of (P2A/P20) between interval [t1 t2]] ;
; where : LAeq = equivalent continuous A-weighted sound pressure level [dB] : p0 = reference pressure level = 20µPa : pA= A-weighted pressure [Pa] : t1 = start time for measurement [s] : t2 = end time for measurement [s]

What does LAeq max 45 dBA mean?
LAeq max 45 dBA refers to the maximum equivalent continuous A-weighted sound level in decibels (dBA) over a specified period, which is set at 45 dBA. This metric measures the average sound level while accounting for the sensitivity of human hearing across different frequencies. An LAeq max of 45 dBA indicates that the noise level should not exceed this threshold to minimize disturbance in the environment, such as in residential or sensitive areas.
