Today, both the deaf and the hearing impaired are rescued by the fusion of medical and technological contributions that range from advanced hearing aids, FM or infrared transmitters as well as cochlear implant surgery.

Once again, the profoundly deaf can hear sounds and determine language thanks to the most exotic method of returning hearing known as cochlear implant or simply bionic ear.

After the implantation surgery, the patient already has electrode channels inside his inner ear or simple his cochlea, while the receiver is within a bone behind his ear.

The patient will then receive a transmitter, speech processor and an externally worn microphone right after the surgery.

Such devices work to stimulate nerve fibers through the implants to send sound and eventually send the brains messages.

The latest would be the 22 channel implant, a version that works by allowing the patient access to a very wide spectrum of pitches.

Thanks to this bionic ear technology, more than 300,000 individuals in US alone can benefit, shares the director from the company that manufactures this device.

For $25,000, the patient will not only be paying for the system and the cost of surgery, but it will also cover the rehabilitation needs that will follow after.

In most occasions, medical insurance or medicaid can be able to handle these costs.

Television listening, as well as going to meetings and public places are now easier for the hearing impaired thanks to the greater range and power of FM devices and infrared than its older counterparts.

For these two systems, what happens is that the sound passes through the radio receiver of the head phone before the user hears it.

The transmitter connects itself to the infrared system, then they are connected either to a microphone or directly on the audio jack of the television before the person can wear the headphone.

Neighbors and viewers will not be disturbed thanks to the head phone’s volume adjust feature. Transmitters of the microphone variety can come in very handy whenever one chooses to have a meeting or even room discussions.

This very head phone can be borrowed and worn at the site, even in areas like temples, churches, theaters and public areas that feature infrared transmitters.

A good example is this company, Infrared listing systems of New York, which has successfully equipped a lot of the theaters and concert halls across New York as long as others across the country with this immensely astonishing technology.

For the consumer who wants a transmitter and head phone for his own use, the cost averages about $125 to $150 for each element.

Based on the user’s profile, the receivers of the FM systems are precisely cut and then reformed. Transmitting sound is the other person, specifically the one speaker who manages to wear the microphone upon his neck.

This can come in handy during meetings or school teaching as this one on one connection inhibits background noise. It will take you about a thousand dollars just to get only the system of the receivers.

Advancement in the circuitry of most hearing aids, which are the most common in terms of instruments for the hearing impaired, enabled it to attain immense power when it comes to the miniscule field of hearing tools and aids.

Depending on the user’s hearing loss profile, most hearing aids with dual channel circuitry balances out the high and low frequencies and be adjusted accordingly.

To enable the wearer to know whether something is actual sound or just noise, the two channel processor works by splitting the frequencies only to fuse them afterward to achieve the perfect proportion.
