feature.)
Stream audio to your hearing aids. Stream audio from Phone, Siri, Music, Videos, and
more by choosing your hearing aids from the AirPlay menu .
Use iPhone as a remote microphone. You can use Live Listen to stream sound from the
microphone in iPhone to your hearing aids. This can help you hear better in some situations
by positioning iPhone nearer the sound source. Triple-click the Home button, choose
Hearing Aids, then tap Start Live Listen.
Use your hearing aids with more than one iOS device. If you pair your hearing aids with
more than one iOS device (both iPhone and iPad, for example), the connection for your
hearing aids automatically switches from one to the other when you do something that
generates audio on the other device, or when you receive a phone call on iPhone. Changes
you make to hearing aid settings on one device are automatically sent to your other iOS
devices. To take advantage of this, all of the devices must be on the same Wi-Fi network
and signed in to iCloud using the same Apple ID.
Hearing Aid Mode
iPhone has a Hearing Aid Mode that, when activated, may reduce interference with some
hearing aid models. Hearing Aid Mode reduces the transmission power of the cellular radio in
the GSM 1900 MHz band and may result in decreased 2G cellular coverage.
Turn on Hearing Aid Mode. Go to Settings > General > Accessibility > Hearing Aids.
Hearing aid compatibility
The FCC has adopted hearing aid compatibility (HAC) rules for digital wireless phones.
These rules require certain phones to be tested and rated under the American National
Standard Institute (ANSI) C63.19-2007 or C63.19-2011 hearing aid compatibility standards.
The ANSI standard for hearing aid compatibility contains two types of ratings:
An “M” rating for reduced radio frequency interference to enable acoustic coupling with
hearing aids that are not operating in telecoil mode
A “T” rating for inductive coupling with hearing aids operating in telecoil mode
These ratings are given on a scale from one to four, where four is the most compatible. A
phone is considered hearing aid compatible under FCC rules if it is rated M3 or M4 for
acoustic coupling and T3 or T4 for inductive coupling.
