A series of high-performance, low-density, nonwoven acoustic absorbers called Thinsulate™ Compressible (TC) Series High Performance Acoustic Insulation is available from 3M. The acoustic absorbers are recommended for novel designs in traditional applications because they are cavity-filling, compressible and comfortable.
Components made with the TC Series compress readily, improving acoustic performance. Also, the designer is able to overcome typical sound package design restraints, such as clearance or tolerance, using a single component. The nonwoven absorbers offer half the density and a 25% better noise reduction coefficient (NRC) at an economical price.
