Phonak M Sensor Receivers

The M Sensor receivers are for use with PhonakAudeo Fit hearing aids which can track the body's health data.

Audeo Fit comes with two receiver options: either a Sensor Receiver or a Sensor cShell. They are hybrids between the receiver-in-the-canal technology consumer wearable devices, so they can deliver sound to a patient's ear and measure health information like heart rate.

For the sound reproduction provided by the receiver, the Sensor Receiver is a M receiver and the Sensor cShell is available as either an M or P receiver. Combined, these receivers have fitting ranges covering a wide range of degree and configuration of hearing loss from mild to severe. Regardless of the power level, the receivers have been combined with something like a pulse oximeter and uses light beams to estimate the heart rate. This method used to track the heart rate is called photoplethysmography (PPG).
