Hearing aids have limitations because they use a speaker to amplify sound. Some of this amplified sound can escape from the ear canal and get picked up by the hearing aid’s microphone which causes feedback, an obnoxious squealing sound. To manage feedback, it is necessary to plug up the ear so that less sound can escape which can cause occlusion.
When the ear canal is plugged, amplified sound waves from the hearing aid speaker reflect and bump into each other causing a distorted or unnatural sound quality. Because Maxum is speaker-less and utilizes an advanced electromagnetic coil and implant which directly drives the inner ear to “amplify” sounds, the result is cleaner, crisper sound quality and more amplification while reducing or eliminating feedback and occlusion.
① Reduce Feedback
Feedback occurs when the sound from a hearing aid speaker leaks back to the microphone. The MAXUM has NO speaker, so feedback is reduced or eliminated.
② Minimize Occlusion
Occlusion, or closing off the ear canal, results in the user’s voice sounding hollow. The MAXUM is “open fit” allowing one’s voice to sound more natural.
③ Improve Sound Quality
The MAXUM System utilizes an electromagnetic coil to “amplify” sounds providing cleaner, crisper sound quality and more amplification.
