Abstract:
1. A computer-implemented method for reducing crosstalk in a headset connected to an audio device, wherein the headset includes a left headphone, a right headphone and a common ground for the left headphone and the right headphone, the method comprising: determining a frequency dependent impedance of the headset; determining a frequency dependent impedance of the common ground; determining, by a processor associated with the audio device, a frequency dependent substantially optimum cross feed for attenuating crosstalk in at least one of the left headphone or the right headphone based on the frequency dependent impedance of the headset and the frequency dependent impedance of the common ground, wherein determining the frequency dependent substantially optimum cross feed includes applying a ratio:  wherein Z(f) applying the frequency dependent substantially optimum cross feed to attenuate the crosstalk in the at least one of the left headphone or the right headphone.
