Rating system: The Federal Communications Commission (FCC) requires phones to be hearing-aid-compatible. Hearing aid compatibility (HAC) is evaluated per the ANSI C63.19 technical standard.
Before December 4, 2023, phones can show HAC compliance with ANSI C63.19-2011 or ANSI C63.19-2019. After December 4, 2023, only ANSI C63.19-2019 is accepted for HAC compliance.
ANSI C63.19-2011 uses the M and T ratings. Per the FCC, a mobile phone is considered hearing-aid-compatible if it’s rated M3 or M4 for acoustic coupling and T3 or T4 for inductive coupling.
-
M rating measures immunity to radio frequency interference for acoustic coupling hearing aids.
-
T rating measures performance when used with an inductive coupling (telecoil) hearing aid.
ANSI C63.19-2019 doesn’t use the M and T ratings of ANSI C63.19-2011. The 2019 ANSI Standard requires phones to:
-
Meet or exceed a single threshold for each test or “PASS.”
-
Meet volume control specifications to be considered hearing-aid-compatible.
To pass the volume control requirement, a phone must meet a two-part test:
-
Conversational gain with a hearing aid: To pass this, a phone must have at least 6 dB of conversational gain with a hearing aid.
-
Conversational gain without a hearing aid: To pass this, a phone must have either:
-
6 dB of conversational gain if tested under the requirements of FCC’s limited waiver (DA 23-914).
-
18 dB of conversational gain if tested without the waiver.
-
Conversational gain refers to acoustic gain, or how loud sound is, compared to a normal, face-to-face conversation.
Note: Handsets with Wi-Fi or Voice Over LTE (VoLTE) calling capabilities may not have been tested for hearing aid compatibility in these calling modes.
If you didn't buy your phone from Google Fi or the Google store, check with your phone's manufacturer for details. For more info, go to the FCC Hearing Aid Compatible Mobile Handsets guide.
For additional information on hearing-aid compatible and non-hearing aid-compatible handsets generally, please visit the Global Accessibility Reporting Initiative (GARI) website at https://www.gari.info/.
