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.
