Each hearing care professional is able to advise and help you choose the perfect solution, using hearing aid, for each specific case according to the hearing loss and ear shape. A hearing aid specially prepared and tailored to the type of hearing loss is the most convenient and effective means that we have available today to achieve and win deafness.
Hearing aids can be classified on the basis of parameters such as size, donning mode, number of microphones and sensor type in:
Intracanal (CIC) A CIC hearing aid is so small as to be virtually invisible from the outside. The CIC are fully customized. They can in fact only be used if the ear canal is sufficiently large, and since they make use of very small sized batteries also require a good manual.
The CIC hearing aids are suitable for mild hearing loss.
The-ear (ITE): This type of hearing aid is worn almost completely within the portion of the external ear canal; an important advantage is constituted by a more physiological listening, and is well accepted from an aesthetic point of view. The-ear hearing aids have limitations in their earning potential; therefore, the risk of bankruptcy prosthesis becomes greater as the hearing loss increases. If a patient with a fairly severe deafness is fully intend to wear a hearing aid ear-you have to make him aware of the possibility of the occurrence of the problem.
TE (BTE): These hearing aids are worn behind the ear. Are widespread and are becoming smaller, their greater size than the other ear devices, allowing for more complex electronic circuits and more powerful amplifiers for cases of severe hearing loss and / or particularly difficult. With the recent developments in the digital BTE hearing aids they are able to automatically adapt to different hearing situations ensuring the patient a perfect listening in all circumstances. The coupling between the hearing aid and the outer and middle ear structures takes place through the so-called "earhook", the tube and the nut; this set determines an important effect on the amplification of the system and can be specially shaped to better adapt the characteristics of the hearing aid to the patient's hearing loss.
AD OCCHIALE: They are indicated in deafness transmission in case of local circumstances that make it impracticable or contraindicate the closure of the external auditory canal due to purulent otitis with otorrhea and specific inflammation. The bone conduction hearing aid electroacoustic characteristics are not satisfactory, as their power is limited. The electronic components are arranged inside one or both arms of the frame. The receiver is replaced by a vibrator which rests on the bone mastoid so as to transmit the vibrations to the cochlea. The contact pressure between the vibrator and the skin can also cause discomfort and local irritation.
