Reverberation time measuring methods

Discrete–time Fourier Series and Fourier Transforms

We now start considering discrete–time signals. A discrete–time signal is a function (real or complex valued) whose argument runs over the integers, rather than over the real line. We shall use square brackets, as in x[n], for discrete–time signals and round parentheses, as in x(t), for continuous–time signals. This is the notation used in EECE 359 and EECE 369. Discrete–time signals arise in t...

Methods of Measuring the Reverberation Time

The goal of this paper is to compare the results of reverberation time measurements obtained with different well-established methods used for this type of measurements, as well as some additional ones which could serve as in situ tool when standard methods are not available. The methods compared in this paper include integrated impulse response measured with pink noise, exponential sweep and ML...
