FM Systems



FM Systems:

Regardless of the distance between speaker and listener the FM receiver transmits the speech directly to the sound processor for listening, at a constant intensity level. The major factors that influence the quality of the speech signal are: background noise, reverberation, and distance. Cochlear implant recipients experience similar difficulties to hearing instrument users in challenging environments. It is well documented that improving the signal-to-noise ratio (SNR – Speech to noise ratio) for cochlear implant users through the use of an FM system significantly improves speech recognition in the presence of background noise.

AUDITERY PROCESS


Switch On (Switching on the External instrument):

Once the cochlear implant surgery is done, with in three weeks the external instrument is fitted. We use latest equipment to fit the external device without any requirement / need of child’s responses. The external device is fitted externally behind the ear.



Auditory Verbal therapy (AVT)
The child using the external device (Processor) attends regular Auditory verbal therapy (AVT), where the child is trained to hear and speak normally using the external device (processor).

Mapping:
After implantation the inner and external device must be monitored, and fine tuning needs to be done to give perfect hearing. MAA pioneers in using the ESRT based fittings where the child’s responses are not required as ESRT is technically monitored.

Clinician to Child set-up
We are the only center in Andhra Pradesh who has one to one training where every child is equally concentrated in their progress. The Childs performance is documented and recorded on periodical bases.
We have 7 acoustic treated rooms to train cochlear implant children.

Parent Guidance Sessions:
We train the parents also to take few sessions on periodical bases where the parents can learn to teach their children at their home.

Group sessions:
The child might perform well in a session, but may not communicate with others. To improve the Childs social behavior we involve every child in group sessions and conduct group activities.

COCHLEAR IMPLANTATION

MAA Cochlear implant Programme:
Our team has an ENT Surgeon (Dr.K.R.Meghanadh), Audiologists and Speech Language pathologists. The surgeon implants the Cochlear implant through the surgical procedures, the audiologist supports on checking the implants status during the surgery and mapping after the surgery and Speech language pathologists work on Speech Rehabilitation after the surgery. It’s a team work where every professional plays a key role.

Cochlear implant:
A cochlear implant is a small, complex electronic device that helps in providing a sense of sound to a person who is profoundly deaf or severely hard-of-hearing. It can restore hearing in patients suffering from deafness due to loss of sensory hair cells in the cochlea. In such patients, it can often restore sufficient hearing. Many people suffer hearing loss because they have damage to hair cells in the inner ear or (cochlea). If hearing nerves work, a cochlear implant can allow you to hear nearly normal.

The cochlear implant has following parts:
  • An external sound processor captures sound and converts it into digital code
  • The sound processor transmits the digitally-coded sound through the coil to the implant
  • The implant converts the digitally-coded sound into electrical impulses and sends them along the electrode array, which is positioned in the cochlea (inner ear)
  • The implant's electrodes stimulate the cochlea's hearing nerve, which then sends the impulses to the brain where they are interpreted as sound.

Pre-cochlear therapy:
Once the child is diagnosed with profound hearing loss, the child is fitted with the hearing aids for pre-cochlear training. Here the child is habituated to use the hearing aid regularly (as the child has to wear the processor – external device in Cochlear implantation) and are provided with adequate speech and language exposure.

Cochlear implant surgery:
Dr. K.R. Meghanadh, MS ENT is expert in Cochlear implant surgery using latest trend technology.

Cochlear implant is one of the most useful medical device invented by science for mankind. Since its discovery in 1980’s thousands of children and adults have been benefited by this modern scientific miracle. There was a time when a congenitally (i.e. by birth) hearing impaired child was condemned to live a life of deaf and dumb, with invent of this device many of the children are living near to normal life.

Once our client is diagnosed with hearing loss and selects a perfect hearing solution – A cochlear implant as a treatment option. We at our center use the latest technology for cochlear implantation, switch on (first fitting), AVT (Auditory Verbal therapy) and oral aural approach. Our clients implanted at right age are performing as near normal children, especially children below 3years of age. Even adults who lost their hearing can opt for cochlear implantation if they want a perfect hearing solution, especially those with profound hearing loss*.

Providence is the leader for diagnosing and treating infants and children in need of speech and hearing intervention. Services include Audiology, hearing care, speech language pathology; our center is fully equipped with latest state of art computerized equipment for diagnosis and re-habilitation of hearing loss that includes Cochlear Implants, Hearing aids and speech therapy.

Services provided to both children and adults include hearing evaluations and treatment for potential hearing loss, speech and language evaluations, therapy for individuals with disorders or difficulties in areas such as speech, oral-motor, stuttering or hearing.

MAA ENT Hospitals, Speech and Hearing center is one of the pioneering hospitals in AP where this surgery is being done since 2004. More than 250 implants surgeries have been done by now and most of them were for the children, we are continuing to provide part of hearing and speech rehabilitation for these children till date. We can proudly claim that our results are comparable to any center of India or the world. Seeing a deaf child hearing and speaking like a normal child is our true reward, a humble continuation to the overall development of our beloved country.
