Short answer: A PSAP (personal sound amplification product) is a wearable amplifier that the FDA describes as intended for people with normal hearing to amplify sounds in certain situations. It is not an alternative to a hearing aid, which is intended to make up for impaired hearing. The FDA describes PSAPs as regulated as consumer electronics rather than medical devices, and hearing aids as medical devices.
This page gives general product and regulatory information. It is not medical advice and does not replace an assessment by a hearing health professional.
Personal sound amplification product definition and scope
The FDA’s consumer update “Hearing Aids and Personal Sound Amplification Products: What to Know” (content current as of 4 May 2023; checked 30 October 2026) states that PSAPs “are intended for people with normal hearing to amplify sounds in certain situations.” Its example uses are recreational activities such as birdwatching or hunting. The same page says PSAPs “are not alternatives to hearing aids” and that they “may be more variable in terms of product quality compared to hearing aids.”
The FDA’s final guidance “Regulatory Requirements for Hearing Aid Devices and Personal Sound Amplification Products” (issued August 2022) is the agency’s guidance document covering both product types together.
PSAP vs hearing aid: what actually separates them
Electronics alone do not decide the category. Under 21 CFR 800.30, a hearing aid is “any wearable device designed for, offered for the purpose of, or represented as aiding persons with” impaired hearing. Design, the purpose for which a product is offered, and how it is represented all count. A product that is marketed to compensate for hearing loss is treated by that definition as a hearing aid, whatever it is called on the box.
The air-conduction hearing aid classification at 21 CFR 874.3300 uses the same intended-use test: “a wearable sound-amplifying device intended to compensate for impaired hearing.” It is a Class I device, subject to general controls and exempt from premarket notification, subject to the limitations in 21 CFR 874.9.
OTC hearing aid vs PSAP
The FDA has established a category of over-the-counter (OTC) hearing aids, so the choice is not only PSAP or prescription hearing aid. The FDA says it created the category “to broaden access to hearing aids.” Under 21 CFR 800.30, an OTC hearing aid is intended for a person aged 18 or older “to compensate for perceived mild to moderate hearing impairment” and is available “without the supervision, prescription, or other order, involvement, or intervention of a licensed person.”
Two labeling consequences follow from the same section. The package must bear the words “OTC” and “hearing aid” on the principal display panel, and sale to people under 18 is prohibited. The text of 800.30 does not mention PSAPs.
Comparison: PSAP, OTC hearing aid and hearing aid
| Question | PSAP | OTC hearing aid | Air-conduction hearing aid (874.3300) |
|---|---|---|---|
| Intended use | Amplify sounds in certain situations for people with normal hearing (FDA consumer update) | Compensate for perceived mild to moderate hearing impairment (21 CFR 800.30) | Compensate for impaired hearing (21 CFR 874.3300) |
| Regulatory category | Regulated as consumer electronics, not a medical device (FDA consumer update) | Hearing aid, a medical device (FDA consumer update; 21 CFR 800.30) | Medical device, Class I (21 CFR 874.3300) |
| Age limit | No age limit stated in the FDA consumer update | Age 18 or older; sale to under-18 prohibited (21 CFR 800.30) | Not set by 874.3300 |
| Required package mark | No package mark stated in the FDA consumer update | “OTC” and “hearing aid” on the principal display panel (21 CFR 800.30) | Not set by 874.3300 |
Hearing aid vs hearing amplifier, and hearing aid vs sound amplifier
“Hearing amplifier” and “sound amplifier” are common shop and search labels, not terms defined in 21 CFR 800.30 or the FDA consumer update. The FDA test is what the product is designed for, offered for, and represented as doing. A device sold to aid people with impaired hearing is a hearing aid under 800.30; a device sold to amplify sounds for people with normal hearing is a PSAP under the FDA’s description.
Where it matters for labs, clinics and supply decisions
Staff who catalogue or label wearable amplifiers can use the sourced points above as a labeling check:
- Read the stated intended use on the label and instructions. Per 800.30, representations that a device aids people with impaired hearing place it in the hearing aid definition.
- An OTC hearing aid carries “OTC” and “hearing aid” on the front of the package. A product without that mark is not presented as an OTC hearing aid.
- Do not treat a PSAP as a hearing aid. The FDA states PSAPs are not alternatives to hearing aids.
For related equipment, see audiometer types, earmold types, hearing aid cleaning tools and zinc-air batteries. For noise exposure rather than hearing loss, see hearing protection types.
Common misunderstandings
- “A PSAP is a cheaper hearing aid.” The FDA says PSAPs are not alternatives to hearing aids; they are intended for people with normal hearing.
- “Anything sold without a prescription is a PSAP.” OTC hearing aids are also sold without a prescription. They are hearing aids and carry the “OTC” and “hearing aid” package marking.
- “The electronics decide the category.” Under 800.30, design, offering and representation decide it.
FAQ
What does PSAP stand for?
Personal sound amplification product.
What is the difference between a PSAP and a hearing aid?
A PSAP is intended for people with normal hearing to amplify sounds in certain situations and is regulated as consumer electronics, not a medical device. A hearing aid is intended to make up for impaired hearing and is a medical device (FDA, 2023).
Is an OTC hearing aid the same as a PSAP?
No. An OTC hearing aid is a hearing aid for adults 18 or older with perceived mild to moderate hearing impairment (21 CFR 800.30). A PSAP is not a hearing aid.
Is a hearing amplifier the same as a hearing aid?
The name does not decide it. What the product is designed for, offered for and represented as doing decides whether it is a hearing aid under 21 CFR 800.30.
