Also refers to the distortion that occurs when some signal from a music source that you are not listening to leaks into the circuit of the source that you are listening to.
A common telephony impairment created by physical twisted wire pairs sharing a bundle.

Impairment typically associated with twisted-pair transmission, where a local transmitter interferes with a local receiver.
The crosstalk is propagated in a direction opposite to the direction of propagation of the signal in the disturbing channel.
