Resonance Air Noise Absorber

Resonance Air Noise Absorber The article considers a sound absorber consisting of a set of parallel operating Helmholtz resonators, presented in different options. The theory and methodology are presented for calculating a broadband sound-absorbing coating for a soundproof wall, which are applicable to other related structures. An example of calculating the acoustic characteristics of a coating is given. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acoustical Physics Springer Journals

Abstract

The article considers a sound absorber consisting of a set of parallel operating Helmholtz resonators, presented in different options. The theory and methodology are presented for calculating a broadband sound-absorbing coating for a soundproof wall, which are applicable to other related structures. An example of calculating the acoustic characteristics of a coating is given.
