REAL TIME MEASUREMENTS - THEORY AND PRAXIS
Wolfgang Ahnert, M BAILEY, Stefan Feistel, Peter A. Mapp · 2023
To measure impulse responses in rooms and free fields is a daily job for acousticians but mainly this is done in unoccupied cases.Results for the occupied case are derived by use of simulation software or by estimations based on experience.Using a newly developed multithread algorithm, speech, music or any other signals from a microphone input and from a mixing console can be utilized to obtain impulse response data for further evaluation.New noise suppression methods and a new developed TFC window are presented that allow these impulse responses to be acquired in full-length even in occupied venues.Practical demonstrations with usual but also unusual sound sources are done.Required measuring conditions and limitations are explained.
