While the second part is totally an outside device. It is made of an antenna, receiver or microphone and a speech processor. The first step is to receive the sound, followed by converting the sound into an electrical signal and finally sending the sound to the inside part of the device.

Post Cochlear Implant

Rehabilitation is essential for those who have undergone cochlear implants and can be imparted at their hospital and auditory rehabilitation centers. The patient needs to know learning and relearning techniques. Hearing through cochlear implant is very different from normal hearing or hearing through hearing aids. While hearing aids amplify sounds to be heard by damaged ears, the cochlear implants directly stimulate the auditory nerve. The auditory nerve then sends  signals to brain which recognizes them as sounds. Over time, the patients learns to hear and enjoy conversations,  environmental sounds and music.

Bone Anchored Hearing Aid (BAHA)

This type of hearing aid is designed to use the body’s natural ability to transmit the sound through bone conduction. Firstly the sound processors picks up the sound, then transfers them into vibrations and finally sends them through the skull bone, straightaway to the inner ear.

Baha (bone conduction implant) is the most effective way of hearing and is meant for those who are deaf or have trouble with middle or outer ear.

The Baha bone induction implant can benefit children with –

  • Children having problems with inner, middle or outer ear (mixed hearing problems)
  • Children having total deafness in one ear (single sided sensorineaural deafness)
