Hearing Aid Compatibility

Motorola Mobility is well aware that hearing aid compatibility is a crucial issue for hearing aid and cochlear implant wearers. That is why we require our phones to create a magnetic field that can be coupled with a telecoil-equipped hearing aid. However, all digital wireless phones, regardless of phone manufacturer or wireless service provider, have the potential to cause interference, such as annoying "buzzing" sounds. To achieve hearing aid compatibility for customers, the specific combination of hearing aid and digital wireless phone must work together.

Hearing aid usability with digital wireless technology does not have one easy, all-encompassing answer to date. Just as with your hearing aid, we recommend that you try before you buy to find the wireless phone that is the 'best fit' for your communication needs. However, if you are not able to reduce interference, please consider using compatible assistive devices with your Motorola wireless phone or speaking to your hearing health professional about the immunity and/or compatibility of your hearing aid with digital wireless phones. More
 

INTERFERENCE SOUNDS

Radio-frequency (RF) interference is based on the transmission of radio waves by the wireless phone and from the electronic components within the phone itself. Different phone designs and form factors may have a mild effect on how much RF interference you experience. Click on each of the following icons to listen* to actual examples of hearing aids experiencing radio-frequency (RF) interference from various digital cellular technologies.

Low-frequency or "baseband" interference has the potential to cause a different type of "buzzing" sound in hearing aids. Differing electrical and mechanical designs can greatly affect the intensity and type of interference. Click on each of the following icons to listen* to actual examples of hearing aids experiencing low-frequency interference from digital wireless phones.
