Here’s another question from our Twitter feed:
Question: What is the sound difference in dB between abutment and magnet?
Answer: Thanks for the question! The Baha Connect System provides the most efficient form of sound transfer to the cochlea. So for patients with larger hearing losses the Baha Connect System may be preferred. However, for the majority of patients seeking a bone conduction implant system, the sound through the Baha Connect and the Baha Attract systems will be similar.
The principle of the Baha Connect and the Baha Attract System is the same, regardless of using an abutment or magnet. Sound is transmitted as vibrations from the sound processor via the abutment or magnets to the implant, which then directs them through the bone to stimulate the inner ear.
For the Baha Attract System, while skin reduces sound in the high frequencies, we have designed the system with that knowledge in mind. Both systems use the same implant secured into the bone which provides an efficient single point of sound transmission. Similarly, for effective transmission, the surface area of the internal and external sound processor magnets have been optimised. Contact surface area is maximised through the use of the unique Baha SoftWear Pad. These innovations combined provide a system where the sound transmission is significantly better than with the Softband, for instance.
Clinically, the sound processors have additional amplification available so any remaining reduction of sound through the soft tissue can be overcome. Additionally, the use of a more powerful sound processor may be required.
Ultimately, the hearing experience for most patients through the Baha Connect and the Baha Attract systems will be similar. Your hearing care professional will be able to provide more information on system selection.
