The Chinese Audiology Network began introducing a unique hearing aid three years ago: a hearing aid in the mouth, a hearing aid that transmits sound through a bone conduction. Its full name in English is SoundBite, which is literally translated as “bite hearing aidâ€, which can be translated as “tooth hearing aid†or “tooth hearing aidâ€. Now it is mostly called “in-mouth hearing aidâ€. The operation of the tooth-transmitting hearing aid is simple. The tooth is used as the bone conduction medium, the collected sound waves are transmitted through the teeth and the skull path, into the cochlea and the auditory nerve, and finally reach the brain to process the auditory signal area, and the principle of the bone conduction vibrator for clinical test hearing. same. Placed on the tooth is a braces-like device with a built-in battery and vibrating receiver that then transmits the sonic information to another receiver that is worn on the ear. Its main component is a high-end digital signal processing unit (DSP). The hearing aid in the mouth has the same amplification effect as the bone anchor type hearing aid, but it does not need to be implanted, and is mainly used for a single-eared patient whose one ear is normal and the other ear is damaged. The inventor of this hearing aid was selected as the "garage inventor" in 2010 by the popular science magazine "Public Science", and since 2011, it has been certified by the US FDA and European CE to enter the market. The Chinese Audiology Network was informed that a recent paper published in the Journal of Nasopharyngoscopy has further validated the clinical effects of this hearing aid. A total of 34 patients participated in the efficacy evaluation trial, which lasted for six months. The results showed that all subjects (100%) indicated that they were willing to recommend mouth-to-mouth hearing aids to other but deaf patients, 90% of whom were Feeling improved in hearing, 80% of patients showed that their communication was greatly improved in a noisy environment. The researchers in this trial believe that the intra-abdominal hearing aids have a greater use value than conventional hearing aids, without the need for surgical implantation and high user satisfaction.
