Bernafon is more a European brand with some Canadian clinics. While it is available to US clinics there isnāt enough volume to concern them with the name used. So the aid is likely disabling tinnitus to meet Costco standards.
Notch filtering can be done to about any aid by the audiologist. At least thatās my understanding. I would think the better Costco fitters could accommodate that.
The tinnitus feature is different from notch and can be duplicated by streaming soft sounds from an app. It works for some and not for others.
I had tinnitus when I started using aids and now donāt. The aids provide more sounds which gives the brain less confusion which resulted in my improvement. Worked for me but wonāt always solve it for others.
If you go with Costco, try one of the tinnitus apps available in the phone store. If it works well, you may prefer switching to a clinic aid with it resident. That avoids the streaming aspect. Many find that the soft sound helps at times but not always. You may want it in a quiet environment but not when you are in others. It can be set up on a program 1 aid as program to and used when you think it helps or just load the tinnitus app on the phone when you want temporary relief.
