R&D Stories: Acoustic Diffusion Research

This article offers a valuable inside perspective about developing new diffuser solutions, and lessons learned while designing countless critical listening rooms around the world. A journey that lead to the creation of the PolyFlex diffuser, which will scatter either horizontally or vertically, depending on the orientation, and improve clarity in speech and spatial focus without making a room sound dead and/or small. The author was actively involved in multiple acoustics standards committees, including for testing procedures.

The August 2022 issue of audioXpress, Acoustics Focus, gives a unique overview of market trends in acoustical products, with great articles on Acoustic Diffusion, Distributed Subwoofers for Room Modes, and Reverberation Control and Measurement. Michel Nieuwenhuizen proposes an improved microphone preamp for condenser microphones, Aren van Waarde builds a minimalist preamp using only discrete transistors, and Ethan Winer shares circuits for VCA and VCF analog synthesizer modules.
