发明名称 VERFAHREN ZUR STÖRBEFREIUNG EINES MIKROPHONSIGNALS
摘要 The noise reduction method uses subtraction of a noise compensation signal from the microphone signal (y), the noise compensation signal provided by simulation of the noise signal via an adaptive filter (H) using a least mean square algorithm, supplied with a reference signal, e.g. a loudspeaker signal, with transformation of the microphone signal, the compensation signal and the output signal into the frequency range.
