An Acoustic Experiment for Generating Pure Material Impulse Response


This paper will present an approach for measuring the reflection impulse response (IR) of various physical materials. Digital signal processing (DSP) techniques are applied to minimize the acoustic influences by the testing environment and test devices, such as speakers, microphones and digital converters. The result IR represents a physical material’s acoustic characteristics and can be used for platforms such as virtual-reality sound generation, acoustic space simulation etc.
