Sound strength

Auditory sound strength is the level at which we experience sound. A reverberant room gives a higher sound level than a room with added sound absorption.

 

High level



Low level


The measurement Strength states the sound level in the real room in relation to the sound level in an anechoic room with the same sound source. The measurement demonstrates the room reflections’ effect on the sound level.
