Abstract

A system and method for dental treatment noise suppression including a first microphone (20) and a first speaker (24) arranged to be located adjacent a first ear of a patient, a second microphone and a second speaker arranged to be located adjacent a second ear of a patient. A first quiet zone generator (22) is operative to receive an input from the first microphone (20) and to provide canceling noise at the first speaker (24), thereby creating a quite zone adjacent the first ear of the patient and a second quiet zone generator operative to receive an input from the second microphone and to provide canceling noise at the second speaker, thereby creating a quite zone adjacent the second ear of the patient.
