Soundproofing Effectiveness

When testing the sound transmissionon class (STC) of a wall or thee noise reduction of a barrier, level contra s measures the difference in sound levels on both side. By counting the number of exceedepencances in thee receiving room, direcers can statistically evaluate how well the partition attenuates sound.
