I hope you get some answers here, cuz I was just talking to my mom about this yesterday. She wears Phonak aids and can not hear her new pastor, who, being female, has a higher pitch.
I’ve often fantasized about a whole NEW industry: techno geeks who focus on hearing-impaired solutions. Initially, these geeks would maybe work at a dispensary or with an audiologist, but honestly, the market is BIG enough to sustain an entire industry.
If I was a college kid in audiology today, that’s the route I’d take. Practical and very useful. How to connect TV streamers to TVs with/without soundbars. How to hear in theatres, churches, community centers, etc. How to pair one’s phone up with a cell phone. What programs are available for optimal hearing: Speech in Noise, Acoustic Phone, et all. Roger pen devices, telephones and conferencing phones for the workplace. Well this just scratches the surface!
