  1. 1. Investigation of the Influence of Incident Angle and Frequency Dependence of a Ceiling Absorber on Room Acoustic Descriptors

    University essay from Lunds universitet/Teknisk akustik; Lunds universitet/Institutionen för byggvetenskaper

    Abstract : The aim of this thesis is to investigate the following: − The influence of incident angle and frequency dependency of a ceiling absorber on room acoustic descriptors − How ceiling absorber properties influence room acoustic descriptors such as reverberation time and steady state sound pressure level − Whether steady state sound pressure level is more related to the statistical absorption coefficient (the average of all incidents) than the reverberation time in a room with an absorbent ceiling − The scattering effect due to furniture in a school classroom The software package WinFlag was used to simulate acoustics in a typical school classroom. The absorption coefficient was computed for several different angles, frequencies and ceiling absorbers. READ MORE
