  • Hearing damage due to excessive sound exposure such as explosions, very loud music, and very noisy machines.

  • An acoustic tumour neuroma is a non-cancerous growth on the balance nerve in the inner ear and near the brain. Acoustic tumours are relatively rare.

  • Age induced hearing loss is also called presbycusis. As people get older many of the hair cells in the inner ear is damaged or disappears, which results in a hearing loss. The degree of an age induced hearing loss vary from person to person, but all people lose some of their hearing as they get older and some loses their hearing earlier and faster than others.

  • Alport Syndrome is characterized by a gradual decline in kidney function and hearing. One in 5,000 is born with this disorder, primarily men.

  • Device which reinforce the sound without changing it. Used in hearing aids but also in other things such like radio and tv.

  • The magnitude of a signal

  • Traditional way of processing signals, where the signals are processed continuously and in real time.

  • The middle of the three little bones in the middle ear that help transmit sound waves from the outer ear to the inner ear. Also called the Incus.

  • Any device other than a hearing aid which helps the hearing impaired

  • A graph showing the ability to hear sounds at different frequencies. The results are stated in dB Hearing Level (HL)

  • An audiologist is a professional who is trained in the science of hearing and hearing impairment, who test peoples hearing, and helps and advice people with hearing impairment.

  • The science dealing with hearing and hearing impaiment.

  • Measurement of the function of an individual persons hearing ability compared with that of normal hearing persons.

  • An auditory brainstem implant (ABI) is a small device that is surgically implanted in the brain of a deaf person who does not have the auditory nerves that lead the sound signals from the ear to the brain.

  • A cranial nerve that leads signals to the brain and transforms them into sound.

  • The auditory tube is also called the Eustachian tube. The Eustachian tube is running from the nasal cavity to the middle ear. The purpose of the eustatian tube is to keep the middle ear space at normal atmospheric pressure. The eustatian tube is usually closed but e.g. opens briefly while swallowing or nose blowing.

  • The outer and visual part of the ear, also called the pinna.

  • Autoimmune Inner Ear Disease (AIED) is a rare condition characterised by progressive hearing loss and/or dizziness which is caused when antibodies or immune cells attack the ear.
