The Hearing Aid Compatibility Act requires the FCC to ensure all telephones manufactured or imported for use in the United States and all "essential" telephones, such as public phones, emergency phones and workplace phones, are hearing aid-compatible.
What makes a telephone hearing aid compatible?
In the United States, about 60 percent of hearing aids contain telecoils, which generally are used by individuals with profound hearing loss.
Many people report feedback or "squealing" when they place the handset of the telephone next to their hearing aid. Telecoil hearing aids can eliminate this feedback because their microphones automatically turn off to block out ambient sound and the hearing aids only amplify the phone signal coming through the telecoil.
Hearing aid compatible phones have an internal feature that allows the use of telephone compatible hearing aids.
Consumer tip: Some hearing-aid users may need to place the ear-piece slightly behind the ear rather than directly over the ear to obtain the clearest signal.
What are the requirements for hearing aid compatibility for wireline telephones?
FCC rules require that phones subject to the HAC Act:
- Produce a magnetic field of sufficient strength and quality to permit coupling with hearing aids that contain telecoils.
- Provide an adequate range of volume.
FCC rules also establish technical parameters to ensure that telephones are compatible with hearing aids.
FCC rules also generally require that telephones allow volume to be increased to accommodate individuals with hearing disabilities whether or not they use hearing aids. Telephones allowing high volume levels must automatically reset to a lower volume each time the handset is returned to an on-hook condition. Telephone equipment manufacturers may request a waiver permitting high volume telephones to remain at the high volume setting under certain conditions.
Are there labeling requirements?
Telephone manufacturers are required to clearly label their telephones and the telephone packaging containing hearing aid-compatible handsets. They must also make information available in the package or product manual, and require service providers to make the performance ratings of hearing aid-compatible telephones available.
