An experimental model to measure the ability of headphones with active noise control to reduce patient’s exposure to noise in an intensive care unit [PDF]
Intensive Care Medicine Experimental, 2017 Background Defining the association between excessive noise in intensive care units, sleep disturbance and morbidity, including delirium, is confounded by the difficulty of implementing successful strategies to reduce patient’s exposure to noise.

A Review of Virtual Sensing Algorithms for Active Noise Control
Algorithms, 2008 Traditional local active noise control systems minimise the measured acoustic pressure to generate a zone of quiet at the physical error sensor location. The resulting zone of quiet is generally limited in size and this requires the physical error sensor

Dental drill noise reduction using a combination of active noise control, passive noise control and adaptive filtering [PDF]
, 2007 Dental drills produce a characteristic high frequency, narrow band 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

Active noise control for high frequencies [PDF]
, 2006 There are many applications that can benefit from Active Noise Control (ANC) such as in aircraft cabins and air conditioning ducts, i.e. in situations where technology interferes with human hearing in a harmful way or disrupts communication.

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