M vs P Receiver: Which One Is Right for My Audiogram & Hearing Needs?

I’ve already posted my . Currently, I’m using an M receiver, as recommended by the Target app, but I’m not satisfied with the output.

During my trial, I used a P receiver and was very satisfied with the hearing aid’s performance. With the M receiver, I’m not getting the same output.

Based on my audiogram, would it be safe and appropriate to switch to a P receiver? What are the possible disadvantages or risks of using a P receiver when an M receiver has been recommended?

Based on my experience I would suggest trying the P receiver and then reducing the or high frequency sounds if you feel your own voice is very disturbing.

If you were much happier with the P receiver during your trial, it’s worth discussing with your audiologist. A P receiver provides more power, but the correct choice depends on your and the hearing aid’s programmed output. Using a stronger receiver unnecessarily can increase feedback, battery use, and the risk of excessive volume. I wouldn’t switch it yourself—have the audiologist verify the fitting and maximum output first.

Yes, this is because output gain is less which target knows, so you need to fit the power receiver and have it recalibrated in target to suit, there is absolutely no "risk" or disadvantage for you at your level of loss, have you got custom molds or using domes.

Have you switched the receiver yourself after your trial?

The aids need to be reconfigured whenever an acoustic parameter like this is changed. For older receiver types the hearing aids cannot detect what type of receiver is attached to them and will not alter their output accordingly.

End-users should stick with the acoustic coupling that their audiologist has prescribed as this is what the hearing aid is expecting and is optimized for. Making changes to this will lead to poor outcomes if you don't know how to reconfigure things correctly. For many brands you need to refit the hearing aid from scratch when making these kinds of changes.

Stick with the p-receivers if this is what your hearing aids are expecting. You'll do a lot better with them.

In recent months I've needed to go a power higher than recommended in Target in order to better meet real ear targets. As long as the fitting is verified I would not expect any safety issues. P receivers are a tad larger than M receivers, so they may feel a little bulkier in the canals.

Go with at least P receiver. I had also suggested M by Target software, but it was bullshit. If P receiver cannot reach high frequency targets and you have some money, you can also try UP receivers in cShells with smaller vent, 0.5-1.5 mm diameter depending on earpiece depth in ear canal and perceived occlusion effect.

YMMV, but in my case I have got the best results with UP in cShell with 1mm vent so far. I am about to test with no vent.

M and P receiver with Unitron thick silicone power domes. UP in titanium cShell with 1mm diameter vent.
