A cochlear implant (CI) is a surgically implanted neuroprosthesis that provides a person who has moderate-to-profound sensorineural hearing loss with sound perception. With the help of therapy, cochlear implants may allow for improved speech understanding in both quiet and noisy environments. A CI bypasses acoustic hearing by direct electrical stimulation of the auditory nerve. Through everyday listening and auditory training, cochlear implants allow both children and adults to learn to interpret those signals as speech and sound.
Sennheiser electronic GmbH & Co. KG is a German audio equipment manufacturer headquartered in Wedemark. Sennheiser specializes in equipment for both the consumer and professional audio markets, including microphones, headphones, and loudspeakers.
A hearing aid is a device designed to improve hearing by making sound audible to a person with hearing loss. Hearing aids are classified as medical devices in most countries, and regulated by the respective regulations. Small audio amplifiers such as personal sound amplification products (PSAPs) or other plain sound reinforcing systems cannot be sold as "hearing aids".
Bone conduction is the conduction of sound to the inner ear primarily through the bones of the skull, allowing the hearer to perceive audio content even if the ear canal is blocked. Bone conduction transmission occurs constantly as sound waves vibrate bone, specifically the bones in the skull, although it is hard for the average individual to distinguish sound being conveyed through the bone as opposed to the sound being conveyed through the air via the ear canal. Intentional transmission of sound through bone can be used with individuals with normal hearing — as with bone-conduction headphones — or as a treatment option for certain types of hearing impairment. Bones are generally more effective at transmitting lower-frequency sounds compared to higher-frequency sounds.
Unilateral hearing loss (UHL) is a type of hearing impairment where there is normal hearing in one ear and impaired hearing in the other ear.

Graeme Milbourne Clark is an Australian Professor of Otolaryngology at the University of Melbourne. Worked in ENT surgery, electronics and speech science contributed towards the development of the multiple-channel cochlear implant. His invention was later marketed by Cochlear Limited.
A bone-anchored hearing aid (BAHA) is a type of hearing aid based on bone conduction. It is primarily suited for people who have conductive hearing losses, unilateral hearing loss, single-sided deafness and people with mixed hearing losses who cannot otherwise wear 'in the ear' or 'behind the ear' hearing aids. They are more expensive than conventional hearing aids, and their placement involves invasive surgery which carries a risk of complications, although when complications do occur, they are usually minor.
Cochlear is a medical device company that designs, manufactures, and supplies the Nucleus cochlear implant, the Hybrid electro-acoustic implant and the Baha bone conduction implant.
The Royal National Throat, Nose and Ear Hospital was a health facility on Gray's Inn Road in London. It closed in October 2019 when services transferred to the new Royal National ENT and Eastman Dental Hospitals on Huntley Street, London, WC1E 6DG. The Huntley Street hospital continues to provide specialist ENT, sleeps and allergy services and is part of University College London Hospitals NHS Foundation Trust.
An auditory brainstem implant (ABI) is a surgically implanted electronic device that provides a sense of sound to a person who is profoundly deaf, due to retrocochlear hearing impairment. In Europe, ABIs have been used in children and adults, and in patients with neurofibromatosis type II.
Auditory-verbal therapy is a method for teaching deaf children to listen and speak using their hearing technology. Auditory-verbal therapy emphasizes listening and seeks to promote the development of the auditory brain to facilitate learning to communicate through talking. It is based on the child's use of optimally fitted hearing technology.
Geoffrey R. Ball (born 1964) is an American physiologist specializing in Biomechanics and the inventor of the VIBRANT SOUNDBRIDGE active middle ear implant – a medical device designed to treat his own hearing loss.
Lars Kolind is a Danish businessman. Kolind holds an M.Sc. in Mathematics from Aarhus University from 1972 and a B.Comm. from the Copenhagen Business School from 1977. He is adjunct professor of leadership and strategy at Aarhus University Business School since 2000. He serves as Detao Master of Leadership and Strategy since 2012.
Implant failure refers to the failure of any medical implant to meet the claims of its manufacturer or the health care provider involved in its installation. Implant failure can have any number of causes. The rates of failure vary for different implants.
Zynex, Inc. is a medical device manufacturer that produces and markets electrotherapy devices for use in pain management, physical rehabilitation, neurological diagnosis and cardiac monitoring. Thomas Sandgaard founded Zynex Medical in 1996.
Cochlear Bone Anchored Solutions is a company based in Gothenburg, Sweden that manufactures and distributes bone conduction hearing solutions under the trademark Baha. The company was founded in 1999 under the name Entific Medical Systems. When Cochlear bought the company in 2005, the name was changed to Cochlear Bone Anchored Solutions. The acronym "BAHA" was trademarked into Baha, as it is not considered a hearing aid by insurance companies.
MED-EL is a global medical technology company specializing in hearing implants and devices. They develop and manufacture products including cochlear implants, middle ear implants and bone conduction systems.
Treatment depends on the specific cause if known as well as the extent, type, and configuration of the hearing loss. Most hearing loss results from age and noise, is progressive, and irreversible. There are currently no approved or recommended treatments to restore hearing; it is commonly managed through using hearing aids. A few specific types of hearing loss are amenable to surgical treatment. In other cases, treatment involves addressing underlying pathologies, but any hearing loss incurred may be permanent.
