Yes its true, decible meters dont messure loudness. Decible meters only messure the peak of a signal. For messuring loudness we invented a different unit, so calles Loudness Units or LU (and also LUFS). In this video I'll tell you everything you need to know about Loudness Units and how to use them in practise. I hope you enjoy :)
