What is a Hemi-Anechoic Chamber?

Hemi-Anechoic Chambers provide a precision free-field environment above a reflecting plane. These chambers are commonly used to test sound sources over a hard, non-acoustically absorbent floor, which is essential for evaluating larger, heavier items. Applications include testing microphones, hearing protection devices, and hi-fi equipment, particularly where operation over a reflective surface, like a floor or road, is typical. The hard floor allows for realistic testing conditions when a fully anechoic environment would be impractical.
