Disturbances that interfere with the transmission, receipt or feedback of a message are called noise.

Noise can be physical, semantic or psychological, and it distorts or blocks the message.

Feedback is the receiver's response back to the sender, the opposite of an interference.

Feed forward is information given before a message to prepare the receiver, not a disturbance.

The channel is the medium that carries the message, not the disruption within it.

Reducing noise is central to keeping communication accurate and clear.
