NRT - Neural Response Telemetry (Intraoperative / Postoperative measurement)
NRT - Neural Response Telemetry (Intraoperative / Postoperative measurement)
The NRT provides a simple way to directly record neural responses. Information from NRT gives the audiologist or surgeon confirmation that the cochlear implant is effectively stimulating the hearing nerve fibres in the inner ear and all conveniently measured within minutes. This is non-invasive, objective, and quicker and does not require sedation or the use of external recording electrodes. NRT can be performed during the cochlear implant surgery and at the follow-up appointments any time after surgery.

Three weeks after the surgery, the audiologist will give your child the external device (speech processor and coil). It is the first mapping of the processor.
Mapping involves the programming of the device by an audiologist who has special expertise in the field of CI. During the mapping process, the stimulation levels of the I internal electrode array are adjusted ‘C’ comfortable and ‘T’ threshold level so that the user can hear the wide range of sounds that he/she may be exposed to.
It is not possible for parents and teachers to listen to a child’s cochlear implant as one would listen to a hearing aid; however, there are other checks of the equipment that should be completed by an audiologist.

Benefits Of Cochlear Implants

Hearing ranges from near normal ability to understand speech to no hearing benefit at all
Many understand speech without lip-reading. However, even if this is not possible, using the implant helps lip-reading
Adults often benefit immediately and continue to improve for about 3 months after the initial tuning sessions. Then, although performance continues to improve, improvements are slower. Cochlear implant users’ performances may continue to improve for several years
Many can make telephone calls and understand familiar voices over the telephone. Some good performers can make normal telephone calls and even understand an unfamiliar speaker. However, not all people who have implants are able to use the phone
Children may improve at a slower pace. A lot of training is needed after implantation to help the child use the new ‘hearing’ he or she now experiences
Many can watch TV more easily, especially when they can also see the speaker’s face. However, listening to the radio is often more difficult as there are no visual cues available
Most perceive loud, medium and soft sounds. People report that they can perceive different types of sounds, such as footsteps, slamming of doors, sounds of engines, ringing of the telephone, barking of dogs, whistling of the tea kettle, rustling of leaves, the sound of a light switch being switched on and off, and so on
Some can enjoy music. Some enjoy the sound of certain instruments (piano or guitar, for example) and certain voices. Others do not hear well enough to enjoy music
