INR as an Estimator for the Decay Range of Room Acoustic Impulse Responses
Ccjm Constant Hak, Jpm Hak, Rhc Remy Wenmaekers · TU/e Research Portal · 2008
A room acoustic impulse response can be used to derive the reverberation time and other parameters. For this a certain minimum energy decay range or effective signal-to-noise ratio is required, which relates to the difference between the initial signal level and the noise level. An impulse response parameter called INR is presented as an estimator for the decay range and shown to be a useful qualifier in practical measurements.
