A disruption in the communication process is called

A disruption in the communication process is called noise.

Noise is anything that interferes with the accurate sending or receiving of a message.

Transgression means the crossing of a rule or limit, which is not a communication term for disruption.

Feedback is the response returned to the sender, not the disturbance itself.

Interaction is the mutual exchange between parties, the very process rather than a break in it.

Whether physical, semantic or psychological, noise names the disruption in the process.
