Why am I getting LA,eq values below the LA,90. Surely that’s impossible?
July 12, 2021

No, it’s not impossible at all, and probably it is related to measuring low levels. By having a think about how statistical levels are calculated, all should become clear. Firstly, the LAeq is the A-weighted equivalent energy over a certain period. It’s independent of time weighting (e.g. F), and the measurement range of the instrument […]
