About ReSound M&RIE Receivers

M&RIE (Microphone & Receiver-In-Ear)

The ReSound M&RIE Receiver (Microphone & Receiver-in-Ear) design combines two conventional microphones with a third microphone that is positioned in the bowl of the ear collecting sounds naturally. ReSound M&RIE receivers use the unique shape of each individual’s ear to collect sound the way nature intended. Wearers get the natural sound of custom products, combined with the advanced features and ease of use of an RIE model, for an immersive and individualized hearing experience with greater depth and direction.

ReSound M&RIE Receivers are available for the ReSound ONE and Omnia hearing aids.

ReSound M&RIE Receiver Pie chart

ReSound M&RIE receiver adds a third microphone that sits in the wearer’s ear canal as part of the receiver module. With this, the unique sound-filtering properties of the wearer’s own anatomy are preserved, allowing the brain to receive the sound as nature intended.

Benefits of the M&RIE include better localization and improved spatial hearing and enhanced sound quality, even compared to pinna compensation algorithms.

Every one of us hears sound shaped by our unique ear, head, and torso combination. This individual and unique filtering of sound is an important determinant of what creates our personal sensation of a natural, transparent, and immersive listening experience in any acoustic environment. Everyone hears differently based on our own physical differences.

ReSound M&RIE Receiver Preferred for Sound Quality and Localisation

Until now, only in-the-ear (ITE) hearing aids, with their microphones placed within the outer ear (pinna), have been able to preserve the spatial cues of the hearing aid user’s unique ear, head, and torso. The ReSound M&RIE receiver changes all that. It is the only receiver-in-ear hearing aid that gives users the personalized benefits of in-ear microphone location and the unique advantages of the RIE style.

Product development research using simulations and prototypes of the ReSound ONE and M&RIE suggested substantial benefits of this approach in terms of localization and sound quality.

M&RIE Study Results

ReSound M&RIE receivers combine all the advantages of traditional RIE-style hearing aids with the benefits of collecting sound in the ear canals of the wearer. Potential benefits of M&RIE receivers include natural sound quality with the wearer’s ability to separate sound sources and judge depth and distance.

Two experiments were carried out with groups of listeners that had normal hearing and hearing loss to validate these benefits. In both experiments, the pattern of results was the same for both groups, but results were more pronounced among those with normal hearing. Sound quality with M&RIE was preferred by both groups over omnidirectionality with the onboard microphone behind the ear in the RIE device. A weaker preference was demonstrated over the proprietary pinna compensation feature using the two onboard microphones of the RIE. Localization performance with M&RIE was similar to unaided and better than omnidirectionality with microphone behind-the-ear location or the proprietary pinna compensation features of various hearing aid brands.
