Abstract: A device for frequency-selective silencing of medical device alarms. The device removes the alarm sounds present in the environment while transmitting other sounds to the patient without distortion. This allows patients to hear everything occurring around them and to communicate effectively without experiencing the negative consequences of audible alarms. The device includes a housing, a microphone, a controller, a filter, and an output circuit. The controller receives the environmental sound including a plurality of frequencies, determines whether a frequency associated with the audible medical alarm is one of the plurality of frequencies in the environmental sound, applies the filter for filtering the frequency associated with the audible medical alarm to the environmental sound, and outputs a filtered version of the environmental sound to a user.
