Localization of Reflections in Auditoriums Using Time Delay Estimation

Document Thumbnail

The impulse response or echogram of a hall enables its acoustic properties to be assessed. The system being studied adds the spatial dimension to this time-energy representation. The method is based on the time delay estimation between microphones of a cubic array with 25-cm edges. The paper presents the results of tests carried out in the Stravinsky Auditorium (Montreux).:
