What hearing aid choose?If you are not very familiar with them , most likely you have the image of the typical huge apparatus behind the ear and almost everyone knows as ” sonotone ” . However all advances technologically and audiology advances daily. Hearing aid manufacturers spend thousands of hours and large sums of money to research and development of its headphones to provide customers always best. To give an example of that work and excellence is Oticon , a world leader in R & D , always to the latest technologically .
How are hearing aids?
We can classify them into several families will explain briefly and clearly
a) According to technology
Analog hearing aids are controlled by trimmer, which are small knobs that adjust with a small screwdriver and basically controls is sound output, to more or less and in some cases control over the treble and bass to calibrate it better patient. The most advanced have some trimmer more to control compression. The disadvantage of these is their wear and tear and ease of adjustment and not save the adjustments accurately. The hearing aid manufacturers are gradually leaving to manufacture Digital Digital hearing aids have a higher sound quality and their settings are maintained stably, are less well being digital allows the introduction of extras systems through its programming software. Examples of these and additional systems that make sense and sound quality is higher quality are:
Feedback cancellers, they come in various types and qualities as for example road simulators or feedback cancellers by correlation.
Speech detection systems.
These are examples of systems of aid depending on the quality of the hearing aid or not take. Obviously these systems influence the final price, higher performance for better sound quality, greater cost thereof. The audiologist will review your profile by exhaustive anamnesis and recommend the best option to be able to hear better. For dynamic people moving in different sound environments, such as house, restaurant, office, association, church, a headset with the best performance are advised that your lifestyle requires it. If your loss is perceptive, making it difficult to capture words or phonemes due to sensory failure, no doubt hearing with aids to speech detection. Until now and from experience in various adaptations, Oticon Alta Pro is the best choice. If you have for example a short, narrow, winding ear canal and you need a lot of power and the mold is at risk of leaks and open adaptation is complicated, we can choose headphones with powerful feedback cancellers. Oticon offers on these technologies and are copied by other manufacturers.
b ) As we reach the sound : Aerial Driving & Bone conduction
BTE , these sound enters through a microphone. Then it is processed and amplified , and a receiver ( speaker ) is sent . This sends the signal directly to the ear canal of the user, through a tube leading to a mold . Within this type we must differentiate :
miniRITE (mini earpiece in the ear)
The miniRITE model is very popular , because of its small size and its extensive features
miniBTE (behind the ear, mini)The miniBTE model is more compact than BTE (BTE ) and offers exceptional acoustic performance , combined with a very discreet design.
BTE (behind the ear)
More powerful than miniRITE and RITE , though extremely discreet.
Sound super power for severe and profound hearing loss. It tends to conform with a mold .
ITE , of which we differentiate :
IIC (invisible in the channel)
The IIC hearing aids enter the ear canal enough to go completely unnoticed by those around him .
