How it works

The Baha® 4 Connect System uses an abutment to transfer sound via bone conduction to the inner ear, naturally.

Getting a Baha solution

So how does the Baha 4 Connect System work? A small implant made of titanium is inserted in the bone behind your ear. A sound processor is then fixed to the top of the implant by an attachment called an abutment. Sound is transmitted as vibrations from the processor via the abutment to the implant, which then directs them through the bone to stimulate the inner ear. It’s a proven and well-tested hearing solution which we’ve been providing for more than 35 years. We have given 120,000 people of all ages worldwide, better hearing and the opportunity to live a more fulfilled life.

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. These sound waves travel through the air and reaches the Baha sound processor.

2. Sound processor

The Baha sound processor picks up the sound waves and a computer chip digitally analyses and enhances the sound depending on your hearing loss and the environment you are in. Sound travels as vibrations from the processor via the abutment to the implant, which then directs the vibrations through the bone to stimulate the inner ear.

3. Implant

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.

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.

How Baha works

The Baha System transfers sound if you are deaf in one ear.

Single-sided sensorineural deafness

In single-sided sensorineural deafness the implant is placed on the deaf side. The sound processor picks up sounds from the deaf side and passes them on to the hearing side through bone conduction.
