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. In this article, NTi Audio explains how to remove reverberation from the measurement results.
