Background

Dynamic range represents the ratio between the loudest signal you can hear and the quietest. Dynamic range is expressed in terms of decibels (dB). Being a ratio, the decibel has no units; everything is relative. Since it is relative, it must be relative to some reference point that has to be defined. Our reference point here is the loudest level you can comfortably bear for one second.

This test helps you benchmark the dynamic range of your sound system.
