Acoutic Attenuators Based On Porous Nanostructured Materials
This technology relates to sound absorption material. Reduction of noise in the environment is important for avoiding hearing loss and for improving psychological health in humans. This technology provides sound absorbing composition that includes particles embedded in a network of nanofibers. The composition contains pores ranging in size from less than 10 nm to more than one micron in diameter and exhibits acoustic transmission loss ranging from 20 to 60 dBcm thickness of the composition.
