Abstract

Embodiments of the invention are directed to systems, methods and computer program products for reducing crosstalk between two systems or between parts of the same system. In some embodiments, a method includes transmitting, from a first signal source, a first input signal to a first amplifier associated with a first audio-listening channel. Additionally, the method includes measuring a signal level along a common path shared by the first audio-listening channel and the second audio-listening channel, wherein the common path includes at least some resistance. Additionally, the method includes determining a compensation signal to be injected into the second audio-listening channel based at least partially on the measured signal level. Additionally, the method includes injecting at least a part of the first input signal into the second audio-listening channel based at least partially on the determined compensation signal, thereby reducing a current level in the second audio-listening channel.
