Abstract |
AB |
[EN] Embodiments of the invention can relate to methods and devices for determining a room acoustic impulse response in a time domain. In one embodiment of a method, an acoustic input signal from an acoustic signal source is emitted into an acoustic room, an acoustic output signal is detected by an acoustic measuring device in the room and fed from the acoustic measuring device to an evaluating device and, by means of the evaluating device, from a reference signal corresponding to the acoustic input signal, and the acoustic output signal, if necessary after prior processing of the acoustic output signal, a room acoustic impulse response in the time domain of the acoustic room is calculated in real time and prepared for output in that, temporally in parallel and continuously, the acoustic input signal is emitted, the acoustic output signal is detected and, by means of the evaluating device, the room acoustic impulse response in the time domain is determined. |
