Free-field microphones are typically used for acoustic measurements in open, unobstructed environments, especially for the use in anechoic chambers and outdoor settings far from reflective surfaces. They are...

A pressure-field is characterized by sound pressure that maintains uniform magnitude and phase throughout the field. This type of sound field can be closely approximated in confined spaces that are small relative to the ...

The reverberation chambers containhard and highly reflective surfaces, where parallel surfaces are avoided. This setup creates a diffuse-field environment in which sound waves arrive simultaneously from all ...
