Mobile phone compatibility rating
Some hearing aid users have reported a buzzing
sound in their hearing aids when they are using
mobile phones, indicating that the mobile
phone and hearing aid may not be compatible.
According to the ANSI C63.19 standard (ANSI
C63.19-2011 American National Standard
Methods of Measurement of Compatibility
Between Wireless Communications Devices
and Hearing Aids), the compatibility of a
particular hearing aid and mobile phone can be
predicted by adding the rating for the hearing
aid immunity to the rating for the mobile phone
emissions. For example, the sum of the hearing
aid rating of 2 (M2/T2) and a telephone rating
of 3 (M3) would result in a combined rating of 5.
Any combined rating that equals at least 5 would
provide “normal use”; a combined rating of 6 or
greater would indicate “excellent performance.”
The immunity of this hearing aid is at least M2/
T2. The equipment performance measurements,
categories and system classifications are based
upon the best information available but cannot
guarantee that all users will be satisfied.
The performance of the individual hearing
aids may vary with individual mobile phones.
Therefore, please try this hearing aid with your
mobile phone or, if you are purchasing a new
phone, please be sure to try it with your hearing
aid prior to purchase.
