Abstract

A 1:50 scale model was built to investigate ways to eradicate the echo. Scale model measurements were carried out using the MIDAS small scale modelling techniques. Four different diffusers were designed. The diffusers were fastened to the walls. Listening tests indicate that the side wall echo has been eliminated.
