Sound muffled, closed domes

As a control, you might check what sound streamed to your ears from your smartphone sounds like, including the sound of people speaking. If that’s very clear and easy to understand, there is something wrong with your external mics or the programming for your external mics. I’m not familiar with the myPhonak app but you might also check the volume, bass, treble, programming settings in your smartphone app to make sure you haven’t accidentally mucked up your usual settings (I’ve sometimes forgotten that I’ve turned off my HA’s via my app to combat something like vacuuming, then later wondered why I don’t hear my wife so well!).

I’ve deliberately worn very occlusive custom-made silicone molds (ReSound Quattros) and when the hearing aids are working correctly and adequately programmed, you should hear sounds and voices very clearly as I’ve been able to when wearing molds that are essentially ear plugs when my HA’s are turned off.

Can you use the old domes for a test?
If it is still muffled with these, your audiologist has done something wrong.
Note: If you definitely want to go back to the old domes, the feedback test must be done again.

I asked what closed domes where for at my last fitting. Dr. said for low frequency loss of hearing. I didn’t see much of that in your audiogram. I’m pretty new to all things related to HAs, so I’m learning.
