Or, do they need them in order to be able to more closely hear things like you and I do, naturally?
Hearing aids are a 'remedial' tool.
I would say that there are many tweaks that work the same way, remedially, at best.
This notion also easily exlpains why so many people do not hear the result of remedial tweaks. They do not require remediation.
May, you claim to work with the hearing impaired, and I believe you.
