Resilient drywall attachment – why?
Wall as an effective noise barrier Sound energy passing through the wall is significantly decreased. When sound (vibrations in the air) impact on one side of the wall, the air pressure variations induce vibration on the wall. These vibrations re-radiate from the other side of the wall as air pressure variations (sound). This effect is highly frequency dependent. Generally low frequencies are attenuated much less than high frequencies. Physical wall assembly parameters that impede sound transmission. Several physical phenomena within the wall affect the...
