US 2025/0095622 A1 · ANGLE INDEPENDENT ACOUSTIC STRUCTURES FOR BROADBAND SOUND ABSORPTION AND SOUND TRANSMISSION LOSS

Abstract

An acoustic structure includes at least one acoustic scatterer that is angle independent and has multiple resonant frequencies. Each acoustic scatterer contains at least one repeated cell. Each cell contains at least two distinct resonant channels capable of absorbing sound and improving sound transmission loss at distinct frequencies. Each resonant channel is identical to at least one other channel within the acoustic scatterer.
