Abstract An acoustic diffuser refers to a device that spreads sound energy uniformly in all directions. Such a device
plays a very important role in architectural acoustics, i.e., concert halls and auditoriums. Many designs such
as the wellknown Schroeder diffusers [1] have been proposed and developed throughout the past several
decades. However, most of these conventional designs achieve uniform sound diffusion by using different
air trenches to create a phase shift profile following a specific sequence such as maximum length sequence
or quadratic residue sequence derived from the number theory [1,2]. As such, these diffusers have… More >
