Sound Sense LV-1 is a low cost, high performance, non-reinforced mass loaded vinyl noise barrier that is recommended for use in many applications due to its versatility. This flexible barrier is frequently used in gypsum wall constructions to substantially reduce the transmission of airborne noise from common sources such as conversational speech, TV or Media audio, or mechanical equipment. When utilized within a floor assembly or above a ceiling, LV-1 is effective at decreasing the transmission of noise to vertically adjacent spaces.
