Low frequency acoustic attenuator and process for making same
A method of manufacturing an acoustic attenuation device includes three-dimensionally printing a pair of sheets and webs that cooperate with the sheets to define attenuation chambers. Each chamber has at least one opening through which excited air resonates.
