In here lies the biggest improvement to UNDERSTANDING speech that HA mfgs have not adequately addressed - noise reduction.
I have owned Bose noise canceling headphones for years and without any question this improves understanding dramatically. As a demonstration of this I asked my wife who is does not have hearing loss to listen to a TV program with the headphones and without. She said both were understandable and comparable in volume but the TV sound quality was a bit better.
I have Widex Beyond HAs. Even with their streamer (in muted mode) it is difficult to understand many speakers without looking at the closed captions. If I listen to the broadcast with my Bose NS700 (wireless headphones) without my Beyonds, the sound is dramatically clearer and I am able to understand most speakers.
With no HA or headphone, I would barely be able to tell that the TV was on!
This improvement in understanding is so profound, I am angry that HA companies have not moved more aggressively to improve the technology they offer. As article inferred, it is clear that their focus is more marketing and less innovation. Where is the Apple, SpaceX or Moderna of the HA industry?
Maybe Bose’s entry will signal a more aggressive move to make consequential improvements.
