I have NHS Oticon hearing aids and I have only had them since May 2024 after being diagnosed early 2024. Previously I had vented domes but I had problems with them repeatedly falling out this year. Turns out losing 20lbs this year has changed my ear shape. I had longer tubes and new domes fitted today but didn’t clock they had given me closed domes. The fit is great and the sound with streaming phone calls/music is so much better. However, I think occlusion is an issue I may need to get used to or just ask for some open domes in the correct size.
As you can see my frequency loss is worse at higher frequencies. Is it worth persevering and getting used to it as my HA’s were originally configured with open domes? Or am I best to get them to send some replacements domes in the post.
Open domes are “supposed to be” good for up to 70 dB high frequency loss. I think most audiologists would put OP in open domes although it’s certainly possible he might end up preferring a more closed fit.
Yeah you’re right, but I’d go custom molds with a vent, pushing the max limits could feedback with open or limit the available gain, I sometimes think there should be something inbetween open and closed, molds with the right venting could be it instead of those tulip type domes they offer.
Personally, I’d use closed domes (2 little holes) as a minimum with your high frequency loss. With open domes, the Feedback Management may strip away some of the high frequency gain you need for clarity.
