Continuous sound level
The equivalent Continuous sound level (in short: LpAeq) is a measure for the average Noise exposure over a certain period in which frequency, duration and level of the individual Sound events are taken into account. The LpAeq is the basis for the determination of noise protection zones pursuant to the aviation noise act – separated according to day (6 – 22 hrs) and night (22 – 6 hrs). The LpAeq is stated in decibels (dB).
