What is the difference between a bone conduction hearing aid and a gas conduction hearing aid?
Bone conduction is the direct transmission of sound to the inner ear using the vibration of the skull. Gas transmission is the use of air to spread through the outer ear, the middle ear is transmitted to the inner ear. You can use your hands to cover your ears first, then talk to yourself as quietly as possible, so that even if your voice is small, you can fully understand what you are talking about. This is the result of bone conduction. Air conduction hearing aids are used more widely. Generally speaking, the box machine, the ear machine, the ear machine, etc. are all air conduction hearing aids. In general, pure tone test, air conduction is not responding, only bone conduction is reactive, it is recommended to use bone conduction hearing aid, bone conduction hearing aid is worn on the posterior mastoid, using vibration to sound.
