Simulating Acoustics of a Room Using MATLAB

Abstract

A speech given inside a big room will always be distorted by the undesirable effect of echo. Taking advantage of the linearities of sound reflections, we propose a method for simulating voices affected by reverberation in different rooms. Our approach is based on the Room Impulse Response (RIR) method and our technique reveals an easy and intuitive way of obtaining the required signals and performing the simulations. A short description of a MATLAB implementation has been also included.
