BIM-based reverberation time analysis

Short Reverberation Time Measurement

The measurement of short reverberation times poses different problems depending at the same time on difficulties of measurement and the sensitivity of the analysis techniques applicable to short signals. This article presents a toolbox, which allows a reliable estimation of reverberation time for small spaces, in a software environment, and using a lightweight system, designed for in-situ measu...

Blind Reverberation Time Estimation

This paper presents a method, which is able to give a blind estimation of the reverberation time of an enclosed space, using only the signal from two or more spatially distributed receivers, for example a binaural signal. There is no need for a controlled or known excitation signal, and there are no special requirements for the excitation signal. The method works with any kind of acoustic sourc...

Conflict analysis in a BIM based design

The development of an engineering design requires the participation of several parties involved in different disciplines, where each discipline conducts its own project in a somewhat disconnected manner from the remaining, therefore requiring project compatibility. In this context, an efficient conflict analysis between disciplines is essential to guarantee a well-developed design. The Building...

A Time-variant Reverberation Algorithm for Reverberation Enhancement Systems

This paper presents a new time-variant reverberation algorithm that can be used in reverberation enhancement systems. In these systems, acoustical feedback is always present and time variance can be used to obtain more gain before instability (GBI). The presented time-variant reverberation algorithm is analyzed and results of a practical GBI test are presented. The proposed reverberation algori...
