Hearing Aid Compatibility for Wireless Telephones

About Hearing Aid Compatibility

As wireless handsets move from analog to digital services, accessibility for the deaf and hard of hearing has become a concern. Digital technology means more features and improved performance—but some digital phones can cause distortion or noise for hearing aid users because of radio frequency (acoustical) interference or telecoil electromechanical (inductive) interference. Hearing aids that operate in an acoustic coupling mode receive and amplify all sound through a microphone, both desired and unwanted. Hearing aids operating in inductive coupling mode turn off the microphone to avoid amplifying ambient noise, and use a telecoil to receive only audio signal-based magnetic fields generated by inductive coupling-capable telephones.

To make sure the deaf and hard of hearing can use digital wireless devices, the Federal Communications Commission (FCC) updated the Hearing Aid Compatibility Act of 1988 (“HAC Act”), passing regulations to increase the number of hearing aid-compatible wireless devices. The FCC’s hearing aid compatibility requirements address devices that operate either through acoustic coupling (with an “M” rating) or through inductive coupling (with a “T” rating). A “3” rating (either M3 or T3) indicates that the device has satisfied the American National Standards Institute (“ANSI”) standard, and a “4” rating indicates that the device exceeds ANSI standards. Although the “M” and “T” ratings are clearly marked on handset packaging, the rating doen not guarantee that the handset will function without distortion or noise. Mobius Cellular therefore recommends that you test the handset before purchasing.

Mobius Cellular strives to ensure accessibility for all individuals, including deaf and hard of hearing consumers. Please, contact our office at (308) 487-5500 or toll free at (877) 266-2487 with questions on hearing aid compability. Additional information on hearing aid compatability is also available for consumers on the FCC website.
