noise. Some hearing devices are more
immune than others to this interference
noise, and mobile devices also vary in the
amount of interference they generate.
The wireless telephone industry has
developed a rating system for wireless
mobile devices to assist hearing device
users find mobile devices that may be
compatible with their hearing devices. Not all
mobile devices have been rated. Mobile
devices that are rated have the rating on
their box or a label located on the box.
The ratings are not guarantees. Results will
vary depending on the user's hearing device
and hearing loss. If your hearing device
happens to be vulnerable to interference,
you may not be able to use a rated mobile
device successfully. Trying out the mobile
device with your hearing device is the best
way to evaluate it for your personal needs.
