Speaker and Microphone Measurements: Eliminate reflections while testing
Acoustic reflections in rooms, in the form of reverberation, contribute significantly to the characteristic of sound. In acoustic measurements for quality testing of loudspeakers and microphones, however, these reflections can produce inaccurate results and should therefore be excluded as far as possible. The measurement results must be reproducible and not significantly influenced by the room acoustics. Good news: there is a viable alternative to building a large anechoic chamber; testing can be done in a reverberant room, and the reverberation can be electronically removed from the measurement results. The process involves time-windowing the impulse response.
