For shortcut access from the Lock screen, turn on Settings > Accessibility > Hearing Aids >
Control on Lock Screen. Use the settings to:
•
Check hearing aid battery status.
•
Adjust ambient microphone volume and equalization.
•
Choose which hearing aids (left, right, or both) receive streaming audio.
•
Control Live Listen.
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 the 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 have more than one iOS device
(both iPhone and iPad, for example), your hearing aid connection 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 logged in to the same iCloud account.
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.
Activate 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.
For iPhone hearing aid compatibility ratings, see www.apple.com/support/hac.
Hearing aid compatibility ratings don’t guarantee that a particular hearing aid works with a
particular phone. Some hearing aids may work well with phones that don’t meet particular
ratings. To ensure interoperability between a hearing aid and a phone, try using them together
before purchase.
