Abstract: A noise abatement system for dental procedures conceived to protect the hearing of dental staff members composed of office managers, dental operators including at least one of dentist, dental hygienist, dental assistant, dental technician and any other dental staff member in the dental operatory, and of patients, comprises a pair of headphones composed of one left and one right phones [1] connected to each other via a flexible strap [2], an audio signal processor (ASP) [7] with a receiver [17] and an on/off talk button [13] with a transmitter and circuitry [21]. Dental operators and patients can toggle an operator/patient switch [8] in a water- and dust-resistant casing of the pair of headphones to switch between operator mode and patient mode.
