In our previous reverberation time measurement tutorial an impulse response, created by bursting a balloon, was used as the measurement signal. This is a quick and simple method of carrying out a reverberation time measurement, but may not be the most accurate method. In this tutorial we will look at an alternative method that can provide improved results.
The reverberation time of a room has a distinct effect on its suitability for different tasks, in this tutorial we will look at the different methods of measuring reverberation time and what the results can show us.
