The Baha® system is unique in the world of hearing treatments
The Baha system utilizes direct bone conduction, which allows the bone to transfer sound to a functioning cochlea – thereby bypassing the middle ear. This unique hearing treatment is the only system of its kind cleared by the Food and Drug Administration (FDA) to treat Hearing losses.
One reason the Baha system works so well is due to its simple design. The Baha system combines a sound processor with an abutment and a small titanium implant. The implant is placed behind the non-functioning ear. Surgery is minor, and Baha recipients report a wide range of advantages over other hearing devices.
The Baha® system utilizes your body’s natural ability to conduct sound. Bone, like air, can conduct sound vibrations. For people with Hearing losses, this provides another pathway to perceive sound.
Typical hearing aids rely on air conduction and a functioning middle ear. In cases where the middle ear function may be blocked, damaged or occluded, the Baha system may be a better option as it bypasses the middle ear altogether. Instead, sound is sent around the damaged or problematic area, naturally stimulating the cochlea through bone conduction. Once the cochlea receives these sound vibrations, the organ ‘hears’ in the same manner as through air conduction; the sound is converted into neural signals and is transferred to the brain, allowing a Baha recipient to perceive sound.
1. A sound processor picks up sound vibrations.
2. An abutment is attached to the sound processor and the implant. The abutment trasfers the sound vibrations from the processor to the implant.
3. A small titanium implant is placed in the bone behind the ear where it fuses with the living bone. This process is called osseointegration. The implant transfers the sound vibrations to the functioning cochlea.
We receive sound in two ways, by air conduction via the ear canal, eardrum, and ossicles, and by bone conduction. Bone conduction transmits sound directly though the bones in the jaw and skull, bypassing the outer and middle ear.
In most cases, those with a Hearing losseswill be fitted with traditional air conduction devices. Typically, these hearing aids are placed inside the ear canal or behind the ear. However, some people are unable to benefit from this type of device.
The Baha system, which is based on bone conduction, utilizes a titanium implant, which is placed in the skull bone behind the ear. An abutment connects the sound processor with the implant in the bone. This creates direct (percutaneous) bone conduction. In contrast, traditional bone conductors connect indirectly to the bone through unbroken skin (transcutaneous) and work by exerting pressure against the skull.
Direct bone conduction, provided by Baha, gives improved access to sound when compared to traditional bone conductors since sound is not weakened when passing through the skin.
