How Baha® reroutes sound
The Baha® System uses bone conduction to transfer sound to the inner ear, naturally.
Follow the steps above, or read below to learn how it works:
1. Sound waves
Sound waves are created by vibrations, for example, the sound of your voice is created by the vibrations of your vocal chords. Like ripples on a pond, the sound waves travel out through the air.
2. Sound processor
The Baha sound processor picks up the sound waves and a computer chip digitally analyses the sound. The digitally enhanced signal is amplified and converted into vibrations that are sent out of the sound processor.
The implant receives the amplified vibrations from the sound processor and sends them through the bone directly to your inner ear, bypassing the outer and middle ear. In single-sided deafness the implant receives the amplified vibrations and sends them through the bone to the hearing ear, bypassing the non-hearing side.
4. Inner ear
The vibrations reach the inner ear and cause waves in the fluid of the cochlea. The hair cells in the inner ear convert the fluid movement into electrical signals sent to the hearing nerve.
5. Hearing nerve
The hearing nerve then sends the information to the brain as electrical impulses, where they are interpreted as sound.
