A cochlear implant is an electronic medical device that does the work of damaged parts of the inner ear (cochlea) to provide sound signals to the brain.
How does a Cochlear Implant work?
Many people suffer hearing loss because their cells in the inner ear (Cochlear) are damaged. The cochlear implant enables the sound to be transferred to your hearing nerve and enables you to hear.
A sound processor worn behind the ear or on the body captures sound and turn it into digital code. The sound processor has a battery that powers the entire system.
The cochlear implant converts the digitally coded sound into electrical impulses and sends them along the electrode array placed in the cochlear.
The implant electrodes stimulate the cochlear hearing nerve which then sends the impulses to the brain where they are interspersed as sound.
What is Auditory Verbal Therapy?
Auditory Verbal therapy is a highly specialist early intervention programme which equips parents with the skills to maximise their deaf child’s speech and language development. The Auditory Verbal approach stimulates auditory brain development and enables deaf children with hearing aids and cochlear implants to make sense of the sound relayed by their devices. As a result, children with hearing loss are better able to develop listening and spoken language skills, with the aim of giving them the same opportunities and an equal start in life as hearing children.
Through play-based therapy sessions, parents are given the tools – Auditory Verbal techniques and strategies – to develop their child’s listening and spoken language. Auditory Verbal therapy enables parents to help their child to make the best possible use of his or her hearing technology and equips parents to check and troubleshoot it in collaboration with their audiology team. This will maximise a child’s access to sound so that listening and spoken language skills can be developed to the fullest extent possible.
AVT differs from other speech and language therapy approaches in a number of ways:
AVT concentrates on developing the listening part of the brain (the auditory cortex) rather than relying solely or partly on visual cues. There is a narrow window within which to develop the brain as a listening brain (rather than predominantly a visual brain, for example), and AVT seeks to make the most of this window of neural plasticity in the first three and a half years of life.
AVT focuses on coaching the parents or carers of the child in the use of Auditory Verbal strategies and techniques in everyday activities and play so that every opportunity is used to develop their child’s listening brain and spoken language skills.
AVT is an early intervention programme. By working intensively with the child in their first few years they should require much less additional support for the rest of their life.
AVT aims to develop the child’s social skills and theory of mind; the ability to understand that their mind differs from another’s. This prepares them to make and keep friends at school.
AVT is delivered by an Auditory Verbal therapist who is a qualified Teacher of the Deaf, Speech and Language Therapist or Audiologist who has undergone three years of post-graduate training to become a listening and spoken language specialist (LSLS Cert AVT), auditory Verbal approach is distinctive in the way it makes the most of a child’s use of hearing as the main sense for developing spoken language. Auditory Verbal therapy is government-funded in Australasia and Denmark and is a mainstream approach in Canada and the United States for teaching children with permanent hearing impairment to listen and speak.
Through play-based sessions using the Auditory Verbal approach, the child develops a listening attitude so that paying attention to the sound around him or her becomes automatic. Hearing and listening become an integral part of communication, play, education and eventually work. All learning from the sessions carries over into daily life. This means that at home, parents can make everyday activities such as setting the table or reading a story into a fun listening and learning opportunity.
