Abstract

This paper presents new approach to enhance the quality of sound signal perceived by the listener in a concert hall considering Spectrogram and Single Spectrum Plot. We simulate a natural concert hall using Digital Echo and Schroeder Reverberator models. We analyze the results using Spectrogram and Single Spectrum Plots and finally propose a model for better analysis of room acoustics.

Keywords: Acoustics Echo Reverberation SIMULINK® Single Spectrum Plot and Spectrogram
