Bone Conduction Hearing Aid Devices And Methods

A bone conduction hearing aid also known as an auditory osseointegrated device aod is designed to transfer sounds through bone conduction to the inner ear.

Bone conduction hearing aid devices and methods. Implantable hearing aids implantation was performed in ten patients and bone conduction implant system implantation was performed in ten patients. The patients used softband ponto oticon by bone conduction and the naída i sp phonak hearing aid set in the opposite ear to the vsb. The hearing is believed to use channels of communications to the brain that are not normally used for hearing. Bahas are for patients with a conductive hearing loss or a mixed hearing loss where the bone conduction thresholds do not exceed 45 db average of 500 hz 1000 hz and 2000 hz.

Selection of hearing aids. The best hearing aid for profound hearing loss should have the capability to do the instantaneous sound conversion so that the hearer can coordinate well with the others. Bone conduction is the process by which sound signals vibrate from the device via the bones to the three. The system consists of a sound processor bone conduction device and a coupling mechanism.

Bone anchored hearing aids baha have been used clinically since 1977 and to date over 7 000 have been fit. Another method that has been used for a long time to treat conductive and mixed hearing losses is the bone conduction hearing aid.

Compared to a traditional bone conduction hearing aid a bone anchored device will not exert any.

We used the nonlinear prescriptive method nal nl1 to calculate and set electroacoustic characteristics based on the tone thresholds entered previously. However for individuals who are not candidates for implant surgery there is a non invasive conduction device that attaches to a specially designed headband that is highly versatile and effective. A bone conduction hearing device is an alternative to a regular hearing aid for those with problems in their outer or middle ears. Twenty patients with bilateral congenital malformation of the external and middle ear were included in the study.

Bone conduction hearing aid devices and methods download pdf info publication number us7664277b2. Bone conduction hearing aids have two essential components. What is bone conduction. It looks like the bone conduction vibrator we use in audiometric bone conduction attached to a metal headband.

Us7664277b2 bone conduction hearing aid devices and methods google patents. An internal implant surgically placed in the bone behind the ear and an external processor. Today google glass employs a bone conduction technique for relaying information to the user. A supersonic bone conduction hearing aid that receives conventional audiometric frequencies and converts them to supersonic frequencies for connection to the human sensory system by vibration bone conduction.
