Oticon Opn 1 (105 dB) little secret of tuning

Hello everyone! I want to share with you the result of my setup. I have oticon opn 1 hearing aids with powerful 105 receivers. To make the sound voluminous and rich and without distortion, it is enough to select the receiver power of 85 dB in the Genie software, not 105 dB. In my subjective opinion, this method is suitable for people with severe hearing loss. Good luck to everyone!

I have the 105db receivers with my Oticon aids, More1, Real1, and INTENT1 aids. By my Gene2 says I should use the 85db receivers but they were distorted at the hifg frequencies. My audiologist switched me to the 105db receivers and no more distorted sound. I am sure my audiologist has my aids in Gene2 set to the 105db receivers though.

I think (only my speculation) 85 receivers produce less unnecessary gain in the left ear area above 3 kHz, which is probably a “dead region” where amplification could lead to distortion.

It is highly probable that setting gain in that left ear area may lead to perceived distortion.

I suppose a similar effect could be achieved with 105 dB receivers, but with frequency transposition or less gain above 3 kHz in the left ear.

If I am wrong, feel free to correct me.

Can somebody comment on what this would actually do? Perhaps lower the MPO?

My hearing loss is such that I should wear 105 receivers with custom mold. Yet for my OPN 1 and now my Real 1, I choose to wear 85 dB receivers with a single-vent bass dome and use to move the high frequencies in my “dead-ear” region of 4KHz and above down to a more audible region around 2 KHz. This allows me to have less occlusion and also be able to let the low frequency sounds in naturally because my low frequency hearing loss is not terribly bad. Incidentally, the audi who prescribed the Real 1 to me fully supported this decision to use the 85 dB with frequency lowering, and in fact, she said she prefers this approach to the 105dB receiver in a custom mold.

So I think just saying that switching from 105 dB to 85 dB is the secret sauce without doing anything else (like using frequency lowering for me) is purely and personally subjective.

From my reading, OP didn’t switch from 105dB to 85dB, he just switched the software. I was wondering what that would actually do. I was guessing just lowering the , but I honestly don’t know.

It sounds like the OP does have 105 receivers.

If I remember right the 105 receivers do not have the frequency span of the 85 receivers. They don’t go as high of frequency.

Ah, OK, I misunderstood what the OP said. I understand now that he keeps the 105 but “fools” Genie 2 into thinking that he only has 85 dB receivers. I guess if Genie 2 thinks that he only has 85 dB receivers, Genie 2 won’t overprescribe the 85 dB receivers’ gains past its limits like it would 105 dB receivers’ gains because it thinks the 105 dB receivers has enough room to withstand the higher gains, and therefore his 105 dB receivers wouldn’t be driven as hard as necessary. So for sure it’s one way to keep the 105 dB receivers from being driven to distortion. As to why it would make the sound voluminous and rich, that’s probably just a personal opinion or maybe something that can perform better if not overdriven.

You might think so. But in practice, I can select the Intent and it will let me specify whatever size receiver I use in order to prescribe the gains for me based on that size. So I can easily just use 105 receivers and select the 85 dB receiver size just like with the OPN or Real or More. So it seems like the communication between the receiver and the hearing aid on the Intent doesn’t really dictate anything about the size of receiver information automatically to Genie 2. It’s still a user-selectable option in Genie 2, even for the Intent.

Are you saying the when hooked up to the aids with 105 receivers you are allowed to set the software at 85? Maybe this is an Oticon thing??? In Target the software knows what receivers are on the aids.

I am fairly sure that the receivers for the INTENT aids are smart enough to prevent Gene2 from being able yo be fooled.

Guys! I’m not going to argue with you and prove anything. I posted my secret of tuning here, and it’s up to you to implement my method in practice. Good luck to everyone.

That’s very interesting. I also wear an Oticon More model with a 105 db receiver. I wonder if there’s any downside or trade-off with such a unique setting that you’ve experienced? Like, for example, will it make it a little more difficult to hear soft sounds? That’s one of my main concerns.

Receiver power vs program settings
I’m set up to use S power receivers with my Phonak M90-13T aids. This is just a curiosity and understanding question, not something I want or need to do. I’m not trying it… just a random thought What would happen if I installed stronger receivers without adjusting anything in the program? Say step up to M or even P receivers? The reason this even came to mind is that I’m in a loaner pair of aids that have M power receivers installed and so I started wondering if the Audi even did anything t…

There’s an interesting post and experiment about issue, thanks to @PaulC.
