Since Widex is getting quite a bit of attention with the new Allure (and I’m planning to trial it as well), I decided to look into it a bit more and I put together an explainer below.
The short of it is that in PureSound mode, there is no really good way to do effective feedback suppression.
It’s possible that Widex implemented the ‘warble’ when the HA detects that you are at risk of impending feedback. The intention would be to disrupt any feedback loop. If that’s the case then I can only think of three options:
- Learn to live with it - it should only happen when in PureSound mode.
- Ask you audiologist to lower your gain settings so that there is more headroom before you are getting into feedback territory. But then you are not getting the gain you should be getting.
- Switch to a more occluded fitting, i.e. use closed domes instead of open ones, etc. You might not like that option either…
