Bone Conduction Hearing Aid

Hearing aid implant is not suitable for little children with congenital aural atresia because their skulls are still growing. Since the critical period of speech and language development is during the first three years of life, the child has to be exposed to verbal stimulation as early as possible. The purpose of this study is to develop an external bone-conduction hearing aid for a newborn child. A headband or spectacle can be used to keep the hearing aid in position. To improve the design of the hearing aid vibrator, finite element analysis was applied to analyze the structure factors that affect the performance of the vibrator. The vibrator and head were simulated as a whole system to acquire more accurate estimation of the spectral response of the bone-conduction hearing aid. The measurement on artificial mastoid shows the vibrator has a wide working range from 200 to 4000 Hz, which covers the most crucial acoustic frequency range for speech recognition. The test of bone conduction hearing aid on adult subjects shows comparative performances with a commercial device. This miniature and low-price bone conduction hearing aid will help the specific group of hearing impaired kids to begin the required early intervention therapy.

Bone Conduction Hearing Aid

Hitherto, for persons with impaired hearing who cannot use an air conduction hearing aid, the only alternative has been a conventional spring-loaded bone conduction hearing aid. Now, with minor surgery, a titanium screw can be implanted in the bone behind the ear and a coupling, which penetrates the skin, can be attached, giving a new kind of hearing aid—the “bone-anchored hearing aid.” Improved quality of sound is one of the patients’ subjective assessments. Improvement was not confirmed by a standard speech-discrimination test. With new speech material consisting of sentences in noise, the speech-to-noise ratio (SN) has been determined for 24 patients. Patients who previously used a conventional bone conduction hearing aid improved their SN on the average by 3.3 dB. The most important difference between the two aids related to improved SN is probably the increased audibility between 600 and 6000 Hz.
