  • Digital reverberation time measurement system
    Patent number: 5227982
    Abstract: Apparatus and method, having both structural and acoustical applicability, for measuring damping of a solid or fluid resonant physical system in terms of reverberation or decay time, featuring a digital computer-based measurement system in which plural numbers of resonances are grouped into single analysis bands. The resonant response is converted into an electronic signal, which is then pre-amplified, filtered, post-amplified, digitized and finally processed so as to determine the reverberation time in the resonant physical system.
