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.

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.
Audiology is a branch of science that studies hearing, balance, and related disorders. Audiologists treat those with hearing loss and proactively prevent related damage. By employing various testing strategies, audiologists aim to determine whether someone has normal sensitivity to sounds. If hearing loss is identified, audiologists determine which portions of hearing are affected, to what degree, and where the lesion causing the hearing loss is found. If an audiologist determines that a hearing loss or vestibular abnormality is present, they will provide recommendations for interventions or rehabilitation.

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.
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.

Ingeborg J. Hochmair-Desoyer is an Austrian electrical engineer and the CEO and CTO of hearing implant company MED-EL. Dr Hochmair and her husband Prof. Erwin Hochmair co-created the first micro-electronic multi-channel cochlear implant in the world. She received the Lasker-DeBakey Clinical Medical Research Award for her contributions towards the development of the modern cochlear implant. She also received the 2015 Russ Prize for bioengineering.
Deafness has varying definitions in cultural and medical contexts. In medical contexts, the meaning of deafness is hearing loss that precludes a person from understanding spoken language, an audiological condition. In this context it is written with a lower case d. It later came to be used in a cultural context to refer to those who primarily communicate through sign language regardless of hearing ability, often capitalized as Deaf and referred to as "big D Deaf" in speech and sign. The two definitions overlap but are not identical, as hearing loss includes cases that are not severe enough to impact spoken language comprehension, while cultural Deafness includes hearing people who use sign language, such as children of deaf adults.
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.
The Bionics Institute is an Australian medical research institute focusing on medical device development. It is located in Melbourne, Australia.
Mohan Kameswaran is an Indian otorhinolaryngologist, medical academic and the founder of MERF Institute of Speech and Hearing, a Chennai-based institution providing advanced training in audiology and speech-language pathology. He is one of the pioneers of cochlear implant surgery in India and a visiting professor at Rajah Muthiah Medical College of the Annamalai University and Sri Ramachandra Medical College and Research Institute, Chennai. He has many firsts to his credit such as the performance of the first auditory brain stem implantation surgery in South and South East Asia, the first pediatric brain stem implantation surgery in Asia, the first totally implantable hearing device surgery in Asia Pacific region, and the first to introduce KTP/532 laser-assisted ENT surgery in India. The Government of India awarded him the fourth highest civilian honour of the Padma Shri, in 2006, for his contributions to Indian medicine.
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.
