Cheol-Ho Jeong, Associate Professor of acoustics at the Technical University of Denmark, talked at EIAS 2023 about the problems of using absorption coefficients as input data for room acoustic simulations. Cheol-Ho has since his professorship in 2011 among many things engaged himself regarding the difficulties surrounding the use of the absorption coefficient, as defined by […]
absorption coefficient
New experimental methods shed light on sound field diffusion in reverberation chambers.
December 13th 2018 we had the privilege to attend a PhD defense at DTU. The work was done by Mélanie Nolan who for the last 3 years has been working intensely to investigate sound fields in the reverberation chamber. This article is touching upon some of the findings from the research. The influence of absorption […]
European Directive bans excessive reverberant noise
The European Directive on Construction Protection against noise applies to all buildings occupied by people. A specific paragraph addresses Reverberant Noise and how to handle it. Intesting is the use of equivalent absorption area. extract from the Directive below: Protection against excessive reverberant noise “The noise within a room is a function, on the one […]
