Abstract: A device and method for improving the performance of an electro-acoustic transducer. An acoustic test signal is generated through the electro-acoustic transducer. The acoustic test signal is measured at multiple points on an ambient surface around the electro-acoustic transducer to create measured acoustic data. Based on the measured acoustic data, an acoustic power frequency response of the electro-acoustic transducer is calculated. A correction impulse response for the electro-acoustic transducer is determined based on the acoustic power frequency response. A correction filter applies the correction impulse response to a sound signal input to generate a sound signal output for playback through the electro-acoustic transducer.

Abstract: The invention relates to the field of acoustics, in particular to methods and devices of correction of acoustic parameters of electro-acoustic transducers and can be applied for improvement of playback parameters of acoustic signals of various electro-acoustic transducers. The offered method of correction of acoustic parameters of electro-acoustic transducer is characteristic with determining of correction parameters of an electro-acoustic transducer by using acoustic power frequency response of electro-acoustic transducer, its evaluation is obtained by taking measurements on ambient surface of electro-acoustic transducer or its segment, measuring results are obtained from many discreet points of this surface or its segment, hereto spectrum of played acoustic test signal is being matched to the spectrum of interference at the measurement site.
