It’s measured in dB and uses a reference level of 20 micro pascals of sound pressure. dB SPL is used widely in … WebThe dBA scale is typically used for quieter environments and there is a significant decrease in weight in the lower frequencies because that mimics how the human ear hears quiet sounds. This can give false readings when measuring music, as the lower frequencies can still hit pretty hard (i.e. kick drums).
