If X-ray is used at all, it will be in very low
doses, and will not affect the hearing aids.
Your hearing aids use the most modern
components to provide the best possible
sound quality in every listening situation.
However, communication devices such as
digital mobile phones can create interference
(a buzzing sound) in hearing aids. If you
experience interference from a mobile phone
being used close by, you can minimize this
interference in a number of ways. Switch
your hearing aids to another program, turn
your head in a different direction or locate
the mobile phone and move away from it.
These hearing aids are classified as IP68.
This means that they are water and dust
resistant and designed to withstand daily
life situations. They can be worn in the rain
but should not be fully submerged in water
or used when taking a shower, swimming
or other water activities. These hearing aids
should never be exposed to chlorinated
water, soap, salt water or other liquids with
a chemical content.
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 aids 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 particular hearing aids and a
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 4 (M4) and
a telephone rating of 3 (M3) would result in a
combined rating of 7. Any combined rating that
equals at least 5 would provide “normal use”; a
combined rating of 6 or greater would indicate
“excellent performance.”
