There was a related post in 2021 about low hiss or floor noise in More 1 HAs (Oticon More 1 Low Hiss in Quiet - #12 by Volusiano). But because the problem I’m having is somewhat different, I started a new topic.
I have Oticon More 1 HAs and am trying to eliminate a constant soft shhh sound that I hear in quiet environments, and only in my left ear. That ear has a small diameter canal that has a fairly sharp bend in it.
The shhh sound is like a radio station that isn’t transmitting a program, but has an audible static-like signal. Or like the sound of wind blowing in the distance.
If I block the opening of my left ear canal with a finger, the shhh noise stops immediately. Because of this, I didn’t see an applicable answer to my problem in the earlier posting and discussion about low hiss or floor noise
I’ve run Genie 2’s Feedback Analyzer one ear at a time, which didn’t detect any feedback problem. The tinnitus program, Speech Rescue, and MoreSound Booster are all turned off. I’m using the VAC+ fitting rationale. With my hearing loss and small ear canals, I use 60dB receivers.
I’ve tried Oticon double bass domes, closed single domes, and open domes. They all fit snugly. No matter what dome I use, when the environment is quiet I hear the constant shhh sound in my left ear. I have usable low frequency hearing, so would prefer to use open domes if possible.
(I also have Phonak Marvel G30 HAs with open domes. I don’t hear any background shhh sound with them.)
The only setting adjustment in Genie 2 which I’ve found that reduces this sound, but doesn’t eliminate it enough to be very tolerable, is by setting MoreSound Intelligence in an Easy Environment to Aware. But the shhh sound is still always noticeable when my surrounding environment is quiet. When set to Balanced or Focused, the shhh sound is louder.
I have Directionality set to Neural Automatic. When set to Full Directional, the shhh sound is louder.
Maybe not important, but as noted by padraighgriffin (Oticon More 1 Low Hiss in Quiet - #31 by padraighgriffin), each time during a fitting session that Genie 2 for a few seconds disconnects from the hearing aids while updating a change of settings, the shhh sound stops in my left HA.
I’d appreciate any suggestions that can make using my More 1s more acceptable. Many thanks!
