Abstract
An apparatus includes an acoustic chamber, an agglomeration of acoustically adsorbing members in the acoustic chamber and suitably located substantially on or in a non-conductive support that comprises a substantially acoustically transparent material, and a transducer configured to generate acoustic waves which enter the acoustic chamber. Each acoustically adsorbing member is separated from neighboring members.
