I would think that turning up the volume would increase the volume at all frequencies by the same amount. But with my Starkey Muse IQ 2400, it seems like the highest frequencies get amplified far more than the lower frequencies, creating much annoying noise? Is this an issue with all brands of HA? Why can’t the electronics amplify at all frequencies in a uniform way?
Perhaps your earmolds or domes simply have large vents and are quite leaky.
In that case, when you turn the volume up, most of the bass escapes outside.
Yeah the volume is increased as per your audogram, so some sounds will increase more then other’s, but it’s evenly across your audogram by a set dB.

Absolutely the bass will not increase much with a leaky fit.
But with a lot of modern hearing aids it actually IS the case that when you turn up the volume it sharpens the sound. This trend started a few years ago with the idea that people knock up the volume when they want to hear speech better and emphasizing consonants improves speech clarity. It was popular, and while we used to have the heads up and the ability to turn that gain shaping off, it’s sometimes just baked in now. It was probably also a successful approach because a huge number of people are regularly underfit in the highs and it helps to situationally overcome this.
I don’t do enough Starkey to know for sure that it’s NOT doing this.

Who knows what algorithm Starkey uses but yes, increasing the volume will not increase the volume at all frequencies equally, in think it depends on the curve gains but it’s a guess
Thanks for the comments. It seems there are some contradictory things going on. If low frequency response suffers from a leaky fit, shouldn’t the volume emphasize the low frequencies more? But in my case, I have a very tight fit, and it’s obvious to me that the high frequencies are most certainly amplified more. Maybe some people want that, but for me, it destroys my ability to understand speech by even the slightest environmental noise. Even with no environmental noise, the high frequencies of the voice I’m trying to understand distort the words so much, I cannot understand.
The important question then is, does anyone know of a HA brand that raises all frequencies by the same amount? As one familiar with acoutsics, the term “amount” is complicated. My guess is that the amount should be in dB.
No. It means the bass leaks more and dB SPL near the eardrum will remain the same, depending on degree of leaks.
The fit may seems tight, but that not necessarily mean it’s not leaky. There are vents and their length and diameter in mm, the latter more important. Gor me, I have quite tight power domes, but it’s leaky a bit, which I see in feedback threshold.
I think it’s better (and less expensive) to try the basics first with a new acoustic coupling. You haven’t written which one you have, what diameter the vent is, or if it is an earmold or domes.
If you don’t make sure of the basics and improve them, you may end up spending a lot of money unnecessarily.
I don’t know which HAs can increase volume more evenly.
You’re probably talking about “gain”.
I wear the Starkey Edge AI.
Had closed domes with two tiny vents.
I now have moulds with vents.
Sound is night and day different between domes and moulds.
Domes would seal the ear.
I could still listen to my translator radio wearing ear hooks with my domes.
I cannot listen to it with my moulds.
I also wore Audible version of the Muses.
Sound between the Muses and Starkey Edge AI completely different.

Your clinician can raise the gain in a more uniform manner.
The other complication is, how long have you had them? Typically more severe loss is at the highs, longer deprivation is at the highs, more loudness dysfunction. Sometimes that perception of high frequency sound overwhelming everything goes away with time and just leaves you with better audibly.
Yes, for the simple notion of an increase in volume or signal output. But it’s a little more complicated. I would agree that we’re talking about the individual gain for each individual frequency band.
Bimodal, sorry I didn’t see your full post. I have in-the-canal speakers with a behind-the-ear main unit. (I’m not familiar with the proper terms.) I’m told that my ear canal is narrow, and I think I have the minimum diameter speaker. I’ll take up your suggestion to try more of the basics. Thanks.
That’s encouraging. Thanks.
freezerman, I have the speaker in the ear canal. Are these “domes”?
Do you think the molds are helping with a better sound, or are there other reasons? Thanks.
Herre is the difference.
Left mould, right dome.
In my case it’s both the mould and the aid.
The Starkey Edge AI is a better hearing aid.
The programming is different.
I can’t say you will definitely do better with the Edge are in moulds.
My loss is in low frequency.
All I know is I can tell the difference.

Could you provide the screenshot what you see?
Maybe it would be better to insert a photo of your acoustic coupling? This “speaker” is called “receiver”, I know, a bit of a confusing term. However, I meant small ventilation hole and canal. The photo should include view of entrance of that hole. It could be good to add your audiogram in your profile settings, it helps with making a more accurate advices.
What model of hearing aid you have specifically?
What’s the model of HA with dome in your photo? Previous generation of Starkey?
It’s an Audible version of a Muse 2400 IQ.
I believe circa 2016 maybe 2017.
