Introduction of Hearing Aids

Hearing aids are devices that are an invaluable aid for those with a hearing loss that can not be treated with medication or surgery and require the use of amplification, like in ear hearing aids.

It is not only necessary but hear better hear best sound depending on the needs required for each case. Therefore it resorts to testing and increasingly sophisticated systems that allow the best prescription, adaptation and verification of hearing aids, like C-109 rechargeable hearing aid.

Once the otolaryngologist diagnosed hearing problem child, known type and degree of hearing loss, and once it recommends the use of hearing aids should proceed without delay to adapt them. You will note that we generally use the plural when speaking of headphones as long as possible should a hearing aid for each ear used; this type is called binaural amplification, like axon hearing aid.

Characterized by electroacoustic amplification of sound waves, their characteristics are predetermined by the manufacturer admitting modifications by manual adjustment controls. The amplifier circuit responds only fixed and varies with the output limitation fixed in adaptation.

Programmable analog hearing aids are amplified through a computerized system rather than manually, offering more flexibility than conventional analog hearing aids. They can have multiple memories that allow to adjust the hearing aid response to the acoustic environment to be operated by the patient.

The development of digital sound processing has been an extraordinary advance in the effectiveness and comfort of hearing aids.

Digital Hearing transform acoustic signals in a binary mathematical code representing the original signal (analog-digital conversion), operating at high speed thanks to microprocessors increasingly smaller. The response of these headphones is of higher quality (high fidelity, reduced background noise automatically to environmental conditions adaptation, etc.) and versatility than previous and supporting greater flexibility in its programming as a result the number of bands and channels used for digital processing of acoustic signals.
