Abstract
Based on a preliminary finding in “Contribution of Floor Treatment Characteristics to Noise Levels in Health Care Facilities Part 2,” we investigate the effect that various adhesives may have in surface generated sound and impact sound transmission levels. The aforementioned study demonstrated that lower source room sound levels were generated with an acrylic adhesive assembly when compared to sound levels generated with a urethane adhesive assembly. These findings led to two follow-up questions: (1) What effect does adhesive have in IIC ratings? and (2) Is there a clear inverse relationship between sound levels within a source and receiving room, and how much does the adhesive affect this relationship? Results from tests conducted in a lab environment with multiple floor finishes and multiple assemblies will be discussed.
