Advanced M$RIE receiver works with its all benefits only for hearing loss audiogram without very steep slop toward severe loss. Second, one can get all the benefits if he/she has enough large open ear canal since M&RIE is more bulky than the standard receivers to be comfortably insert further inside.
In this blog there is attached one photo of M&RIE receiver insert not well in the canal, sticking out enough which shows rather not good fit. Unfortunately I was unable to attached my M&RIE photo which shows a good fit of this receivers as demo.
Third M&RIE receivers are not described really well in detail in order the users to understand how in different environments to get a max positive effect. Find below Resound trainer input about these advanced receivers and turning on their program what can give you in more details:
The M&RIE receivers work in different ways in the programs he has. They are active in program 1 and 3, with program 3 being exclusively M&RIE – while program 1 will use all the microphones on the hearing aid when appropriate.
In program 1 (All-Around) the hearing aid microphones go through these directional patterns depending on the listening environment. More complexity in the environment means a higher likelihood of using the directional modes. For your case, OMNI also means M&RIE mic. For the middle states, where one is M&RIE and one is top-mic directional, several things contribute to the hearing aid’s decision of which ear plays which role. In general, the better ear tends to be the directional ear (left in your case). But if the sound environment is very different left versus right – that also contributes to which ear goes directional. For instance if all the noise was on the left and the person of interest on the right, likely Right would go directional.
Changing the volume of the hearing aid does not change the directional mode, most likely the left ear switching to directional when watching a TV program has to do with the complexity of speech and noise / sound effects/ etc.
Program 2 (hear in noise) is a narrow directional program – using the top microphone to create a narrow beam. “who you are looking at is who you want to hear”. M&RIE is not a part of this program.
New Program 3 (outdoor) will never switch to the top microphones. This is a program that ONLY uses the M&RIE mic down in the ear canal. It is called outdoors because outdoor environments are typically the use case where we don’t want the hearing aids to go directional without the patient’s consent/choice. The benefits are natural wind noise reduction and localization – pinna effect. Recommendation is that this program can be used at home when watching the TV if you don’t like when your left device switches which microphone is dominant. This program is not recommended as a replacement to all day use, as it does not handle complex environments as intelligently as program
