With more closed type domes, and either phonak or widex models, what do HAs actually DO with sound below 250 and above 8000? I’m a composer and music mixer/engineer, and wonder if with closed domes, I am effectively filtering out below 250 and above 8k? I think I’d rather (with working on music) let my own hearing perceive below 250 and above 8k, and the hearing aids do the rest, rather than let the HA ignore those frequencies. Am I missing something? Thank you!!
Phonak Lumity (depending on what receiver you use as it could be less) only process to 8000 Htz so obviously a more closed dome means you can’t use your national hearing.
The receivers go as low as <100 Htz.
thank you - would that be a steep drop-off at 100 and 8k?
yeah - it doesnt really state what the drop off (slope) is. interesting stuff.
I might be wrong but I think there won’t be anything above 800 Htz at all.
and if that’s true for above 8k AND below 250, that’s a whole lotta music missing. especially below 100. that’s an argument for open, if the hearing is there, or the perception of hearing and brain adaptation.
But the receivers go <100?!

Hearing ears and how hearing aids work unfortunately are very different.
yes - i had 250 in my head - i meant 100. thanks
You will get below and above those quoted but by how much? in fact one forum member claimed as low as 20 and and I think upto 10,000Hz, he used a tone generator to check this, there’s a few different models/brands that claim to reproduce upto 12,000HZ
great online tool!! thanks for this!!!
Hearing aids are at best a poor compromise for music. If you look at the frequency response of the receiver, you’ll see it gets pretty wonky at high frequencies. Also at high frequencies, since the processing isn’t instantaneous, there would be large phase differences, including cancellation at certain frequencies. With open domes the feedback manager destroys the music. Ah, that lovely oboe going wa-wa-wa!
i need closed domes because of my LF loss. Even with the drop-off at low frequencies of the hearing aids, I hear the low notes, probably because I hear the overtones and my brain reconstructs the note. Not as well as I did decades ago, but…
Marshall Chasin has done a lot of good work on the subject of hearing aids for musicians. Do a search for him.
For anyone interested
Does this mean that I should not use frequency compression in the Music program even if it means totally losing the high notes?
Yes, you don’t want digital artefacts which a lot of the time is happening when you use this feature for music, you won’t be missing your high’s like your thinking, your HAs are made for speech foremost and music as a after thought.
