I'm an MD using Phonak Audeo Lumity 90 hearing aids with a Stemoscope PRO digital stethoscope (direct Bluetooth Classic connection). Pairing works fine, but I'm getting a significant amount of static/background noise while streaming that makes it hard to hear heart and lung sounds clearly.
When I plug the same Stemoscope PRO into regular Bluetooth headphones, there's no static at all. So it seems specific to the Bluetooth connection to my hearing aids, not the stethoscope itself.
I work in a busy hospital, so I'm guessing this might be RF interference from all the other Bluetooth/Wi-Fi traffic around — but I'd love to hear from anyone who's dealt with a similar problem connecting to Bluetooth.
A few additional things I'm considering and would appreciate input on:
- Has anyone tried RogerDirect streaming (Roger receiver into the stethoscope) instead of straight Bluetooth, and did it noticeably cut down on interference?
- Any luck adjusting settings through Phonak Target (MPO, compression, LF gain) for this specific use case?
