Active noise control on high frequency narrow band dental drill noise: Preliminary results [PDF]

open access: yes, 2007
Dental drills produce a characteristic noise that is uncomfortable for patients and is also known to be harmful to dentists under prolonged exposure. It is therefore desirable to protect the patient and dentist whilst allowing two-way communication.
