No FDA or State regulations!
Deaf? You would go to your ENT or Audiologist for a physical examination, just as now. If you are in the 90% (estimated) who simply have a age related loss (SNHF) you would have unlimited choices of how and where you buy your aids.
You could buy your aids from the audiologist probably at a much lower price than you now pay and arrange to pay additional for services and adjustments as needed. Just like with an MD.
Or you could go to the drug store or WalMart and pick up a pair of aids at a small fraction of the cost from today’s licensed sources.
But these drug store aids will not be like the aids we have today. First they will come with a package of a half a dozen snap on molds to fit most canals. Second they will come with a small simple remote control that has buttons for stepping through a dozen or more settings for the most common types of loss curves and compressions. And they will be sold by the giant drug stores or retail chain stores with a 100% satisfaction guarantee. Or you could buy them from Amazon etc.
Because of mass advertising, aids are no longer considered to have a stigma attached. And because of the ease of purchase and guarantee the 20 million (in USA alone) that are hard of hearing but do not wear aids would be brought into the market. And prices will be commensurate with other similar electronic goods.
The other 10% that have severe/profound losses or disease, or are children, or infirm, or are affluent must or will use the professional services.
