Diffuse-Field Microphone Sets 
 

Unlike an anechoic chamber, a reverberation chamber is designed with hard, reflective, and non-parallel surfaces, creating a highly reflective environment. This results in a diffuse sound field, where sound waves arrive from all directions with equal energy and probability.

​

Real-world conditions that closely resemble diffuse fields include buildings with hard surfaces, or spaces where multiple sound sources are present simultaneously—such as vehicle cabins, churches, or large industrial rooms.

Diffuse-field microphones are best suited for applications like in-cabin noise measurement, building acoustics, and other environments where reflected sound dominates.
