Bone conduction hearing aid–Bone conduction hearing aid[image]
The bone conduction hearing aid is a relatively rare and high-tech hearing aid type among many hearing aids. It is different from the air conduction hearing aid to transmit sound signals to the inner ear through airborne transmission. The bone conduction hearing aid is transmitted through the bone, and the oscillator is inserted through the soft belt or the surgery. The way, causing vibration on the skull, amplifying the vibrational energy of the sound wave, and transmitting the sound signal directly to the inner ear. Mainly used for people with chronic otitis media, congenital ear canal atresia, hearing loss of small bone disease. However, due to the high cost of bone conduction hearing aids and the low demand in the hearing aid market, the public knows very little about them. At present, the main production of bone conduction hearing aids is the internationally renowned hearing aid brand Oticon.
Oticon is the world’s leading manufacturer of hearing aids. Products in China, the United States, Canada, Australia, Japan and other nearly 100 countries, the first to develop bone conduction hearing aids has exceeded20Year history. It has provided critically acclaimed services to hundreds of thousands of patients with ear diseases worldwide, allowing the stop-loss population to regain their hearing.
PointWhat are the advantages of bone anchored hearing aids?
1.Because the bone conduction hearing aid is directly transmitted to the inner ear, it does not block the outer ear, does not cause the ear plug effect, avoids the patient’s discomfort, and the overall sound quality is less distorted than the air conduction hearing aid. At the same time, the secondary damage of the tympanic membrane and the ossicular chain caused by the high gain of the air conduction hearing aid is avoided, which has a certain protective effect on hearing.
2.Most elderly people with age, the outer ear, middle ear will be accompanied by narrowing of the ear canal, long ear hair, tympanic membrane turbidity, invagination or atrophy, embolism and other symptoms, which directly or indirectly affect the transmission of air conduction hearing aids effect. The bone conduction hearing aid avoids this, and the sound is directly transmitted to the inner ear, and the loss of energy is also reduced, and the degree of sound reduction is high.
3.The hair band appearance allows children to enjoy a normal and active life.
