Waterproof and Sweatproof Bluetooth Earphone Headphone

Can a deaf person wear bone conduction earphones (Handsfree Earphone) ?

Yes, because deaf people can hear their own voice through bone transmission!

There are three types of deafness, namely conductive deafness (damage to the air conduction pathway), neurological deafness (damage to the inner ear) and mixed deafness.

There are two ways for the human ear to hear sound, one is air conduction and the other is bone conduction.

Bone conduction can be used for conductive deafness. The so-called conductive deafness is damage to the "air conduction" pathway, such as otitis media and rupture of the periosteum. These can be done by bone conduction. From this perspective, patients with conductive deafness can indeed hear sound through bone conduction.

For neurological deafness, bone conduction hearing aids and air conduction hearing aids are the same, but because the technology of bone conduction hearing aids is still worse, most hearing aids that use air conduction are the traditional hearing aids you asked. Because neurological deafness is a disease of the inner ear, the number of hair cells in the cochlea decreases.

At present, bone conduction technology is more used in tws earphone products worn by some hearing people. There are products used to compensate hearing, but sales are very low. The main problem is: noise handling. Even the implantable bone conduction hearing aids, BAHA and Sophono, which have become popular in recent years, have not achieved good sound effects. Some users will report hearing sounds that should not be heard, such as heartbeat, blood flow, and so on.

As for congenital or acquired deafness, this problem has nothing to do with bone conduction. Whether congenital or acquired, there are both conductive and neurological deafness.
