Walk into any electronics aisle today and you'll find three categories of devices that all promise better hearing: prescription hearing aids, over-the-counter (OTC) hearing aids, and personal sound amplification products (PSAPs). They look similar and are often marketed similarly, but the FDA treats them very differently — and knowing the distinction can save you money and protect your hearing.
Personal Sound Amplification Products (PSAPs)
According to the FDA, PSAPs are built for people with normal hearing who want to amplify sound in specific situations, such as birdwatching or hunting. They are electronic products, not medical devices, which means they aren't required to meet any hearing-loss-specific safety or performance standards. If a PSAP is marketed as a treatment for hearing loss, that's a red flag — it's stepping outside its intended use.
OTC Hearing Aids
This is a newer category, established by an FDA rule, for adults 18 and older with perceived mild-to-moderate hearing loss. Unlike PSAPs, OTC hearing aids are regulated as medical devices and must meet FDA design and performance requirements, including volume limits designed to prevent overamplification damage. You don't need an exam, a prescription, a professional fitting, or a licensed seller to buy one.
Prescription Hearing Aids
These remain the option for people of any age and any degree of hearing loss, including severe cases. They require a prescription, and in some states must be purchased through a licensed seller, because a hearing professional needs to program them to your specific hearing profile.
Why this matters: The FDA estimates that close to 30 million U.S. adults have some degree of hearing loss. Many will genuinely benefit from an OTC device; others — especially those with severe loss or complicating factors — need the professional oversight that comes with a prescription. PSAPs were never designed or tested for treating hearing loss in the first place, so they don't belong in that conversation at all.
If you're shopping for relief from everyday hearing difficulty, look for the words "FDA-registered hearing aid," not "sound amplifier."
