Bone Conduction Hearing Aids Explained Plus Use of Headbands
Bone conduction hearing aids can help certain types of hearing loss, and are usually of help in the case of youngsters. Others who also benefit particularly from this sort of hearing help are those who have transient hearing loss.
This should be caused by physical damage, blockage, infection or eczema. Typical hearing aids take sounds from outside of the ear, and then amplify this sound and play it back to the inner ear. There are newly developed hearing aids called bone conduction hearing aids, these work way differently to the traditional hearing aids.
Traditional external hearing aids can be generally subdivided into air conduction hearing aids and bone conduction hearing aids.
Air conduction hearing aids require the employment of ear molds, that may be problematic in hearing loss sufferers with protracted middle ear and ear canal infections, atresia of the outer canal, or an ear canal which cannot allow entry of an ear piece.
As a result a new kind of hearing help has been developed namely the bone conduction hearing aid, and employ as their main component an oscillator. It picks up sounds from the outside of the ear and introduces vibratory motions onto the skull.
This is a signal that is heard by the inner ear. There is massive difference between Bone Conduction Hearing Aids and other models available today on the market. Both take the sound from outside of the ear. However, a conventional model amplifies the sound within the middle ear, in the ear mould. The inner ear then receives the sounds from the ear mold. The Bone Conductor Hearing help is dissimilar.
It conveys the signal picked up outside the ear, straight to the oscillator. The oscillator vibrates against the skull which the inner ear recognizes as sound. though the Bone Conduction Hearing help isn’t as efficient as the other hearing aids available, but it is good for those whose condition is unsuitable for the regular kind of aid.
In these patients, bone conduction hearing aids may be an alternative. External bone conduction hearing aids function by broadcasting sound waves through the bone to the ossicles of the middle ear. The external devices must be closely applied to the temporal bone, with either a steel spring over the top of the head or with the employment of a spring-loaded arm on a pair of glasses.
These devices may be associated with either pressure headaches or soreness. While the bone-anchored hearing aids have sometimes been utilized for those with conductive hearing loss, their use has been analyzed in patients with unilateral sensorineural hearing impairment.
Hard headbands for bone conduction hearing aids have given problems. There are some options for bone conduction headbands for bone conduction hearing aids. If cosmetics are the main problem, some parents have stitched the headband into a favorite hat ( that often helps with comfort too ).
Girls can use butterfly clips both to decorate and to anchor the headband in their hair. Some youngsters use sports headbands. Make a slit on the inside only of one side and run the wire through the headband to a matching slit on the opposite side, just above the ear.
Also remember that the oscillator must immediately contact the skin and must be attached in such a manner that nothing comes between the oscillator and the skin. Regularly just the fit of the headband will achieve this but if not velcro should be attached to the back of the oscillator.
