to attract the hearing – impaired people

to inform medical personnel of a new device

to urge doctors to use the new device

to describe a new cure for ear infections

Because it takes little time to produce clearer sound.

Because it gives vibrations to the magnet

Because it gives sound directly to the inner ear

Because it transmits vibrations directly to the magnet and then to the inner ear

Because it transmits sound faster to the ear

Only those with a hearing loss caused by infection other in middle ear

Only those who have problem in middle ear

Only those who have problem in inner ear

Only those who have ear infection
