  1. Acoustic Neuroma
    A tumor, usually benign, which develops on the hearing and balance nerve and can cause gradual hearing loss, tinnitus and dizziness
  2. Acute Otitis Media
    An infection of the middle ear that often includes pain, fever and conductive hearing loss.
  3. AGC - Automatic Gain Control
    A form of hearing aid circuitry that automatically adjusts the volume of sound so it remains within a comfortable listening range for the person wearing the hearing aid.
  4. ASP- Automatic Signal Processing
    Methods of altering the input to analog hearing aids to improve hearing.
  5. Air Bone Gap
    Any difference between how a person should hear and how they actually hear if some of the sound is being lost as it passes through the middle ear.
  6. Amplitude
    The physical intensity of a sound. (subjective impression of loudness)
  7. Assisted Listening Devices (ALDs)
    Tools and devices such as alarms, alerting devices, or FM systems used to help people hear to perform daily actions, tasks and activities.
  8. Asymmetrical Hearing Loss
    The degree of hearing loss in one ear is greater than the other.
  9. Atresia
    Absence or malformation of the outer or middle ear.  EX: there may be no pinna or ear canal.
  10. Attenuate
    To decrease the amplitude (loudness) or energy of a signal.
  11. Auditory Brainstem Response (ABR) Test
    Used to test the hearing of infants and young chrildren or to test the functioning of the hearing nerve. This painless procedure involves attaching recording disks to the heard to record electrical activity form the hearing ne\erve and brain stem
  12. Auditory Nerve
    Eight cranial nerve that connects the inner ear to the brain.
  13. Auditory Reflex
    Reflex that occurs in response to a loud sound (involuntary stapedius muscle contraction).
  14. Auditory Perception
    Ability to identify, interpret and attach meaning to sound.
  15. Auditory Processing Disorder (ADP)
    Inability of an individual with normal hearing and intelligence to differentiate, recognize, or understand sounds normally
  16. Auricle
    The external ear
  17. Autoimmune Hearing Loss
    Hearing loss when one's immune system produces abnormal antibodies that react against the body's healthy tissues. May be associated with tissue-causing disease, such as rheumatioid arthritis or lups.
  18. Bone Anchored Hearing Aid (BAHA)
    This is a special kind of bone conduction hearing aid. A titanium post is surgically implanted into the mastoid bone behind the ear. Once this area around the post heals and the bone firmly grows around it (about a month), the hearing aid istself is snapped into the post. The hearing aid vibrates the post, which in turn vibrates your skull, which in turn shakes your cochlea and you hear the sound. BAHA works best with for conductive hearing loss
  19. Bandwidth
    Total area of frequencies that a hearing aid amplifies (generally from 125 Hz to 5500Hz)
  20. Barotrauma
    Injury to the middle ear caused by a rapid change of air or water pressure.
  21. Behind the Ear (BTE) Hearing Aids
    These aids sit behind your ear and are connected to an ear mold placed inside your ear via tubing. BTE hearing aids are known for being robust and durable. They are practical in that they have the ability to produce a lot of power.
  22. BICROS hearing aids
    Bilateral Contra Routing Of Signals

    A hearing aid designed for a person who has hearing loss in one ear and is deaf in the other. This hearing aid picks up sounds on the non hearing side and transmits them to the better ear and amplifies the better ear so the person wearing a BICROS aid can hear people speaking from his/her deaf side.
  23. Bilateral Hearing Loss
    A hearing loss in both ears
  24. Binaural
    Refers to two ears
  25. Bone Conduction Hearing Aid
    A hearing aid that transfers sound through the skull instead through the ear canal (air conduction).
  26. Carhart Notch
    Hallmark audiological sign of otosclerosis. It appears as a sensorineural hearing loss at 2kHz that is spurious (fake) as the bone conduction in the mid frequency range is not reliable.
  27. Central Auditory Processing Disorder (CAPD)
    A language disorder that involves the perception and processing of information that has been heard. Children with CAPD have problems following spoken instructions and usually show other language learning problems, even though the inner ear is function normally.
  28. Cholesteatoma
    An abnormal accumulation and pocketing of dead cells in the eardrum, which can often be surgically repaired.
  29. Cilia
    The tiny hairs within the chochlea
  30. Cochlea Nerve
    Sometimes called the auditory nerve or the acoustic nerve. One of the two branches of the eighth cranial nerve. It conducts the hearing signals from the inner ear to the brain.
  31. Compression
    A type of circuitry that is used to keep soft sounds audible and loud sounds comfortable
  32. Concha
    The bowl shaped part of the pinna near the ear canal
  33. Cognition
    Thinking skills that include perception, memory, awareness, reasoning, judgement, intellect and imagination
  34. CROS
    Contralateral Routing Of Sound. A hearing air designed for a person who has normal hearing in one ear and is deaf in the other. This hearing aid picks up sounds on the non hearing side and transmits them to the good ear so the person wearing a CROS aid can hear people speaking from his/her deaf side.
  35. Cookie Bite Hearing Loss
    Named for the shape of this kind of hearing loss on an audiogram. Both the high and low frequencies are normal or near normal, but there is a broad dip in the mid frequencies that looks like someone literally took a bite out of the top of the audiogram.
  36. D/A Converter
    Digital To Analog Converter

    Changes the digital signal coming out of the amplifier into an analog sound that we can understand.
  37. Datalogging
    Feature in some digital products that keeps a record of what kind of environments the user has been exposed to, battery life, hours of usage, and may even make recommendations for adjustments.
  38. Desired Sensation Level
    A hearing aid fitting method (prescriptive formula) designed specifically for children.
  39. Digital
    A type of amplifier system that changes analog sound into a series of binary numbers for processing.
  40. Digital Hearing Aid
    A hearing aid that provides amplification by processing sounds as bits (numbers) instead of as voltage. Digital hearing aids can control or modify sound in almost an infinite number of ways through its programs
  41. Digital Signal Processor (DSP)
    A microprocessor that converts analog sound to a digital signal
  42. Directional Microphone System
    Multiple microphone system that amplifies sound from the front more than sound form the rear for better hearing in noise.
  43. Disarticulation
    A break or separation in the middle ear bones.
  44. Discrimination
    Hearing clarity

    The ability to tell apart (discriminate between) similar sounding words such as "fun" and "sun". People with normal hearing generally have 100% discrimination. If your discrimination scores drop below 40 to 50% you won't understand much of what you hear, no matter how loud it is. Speech then sounds more like gibberish or a foreign language. Discrimination is always expressed as a percentage called word recognition.
  45. Dynamic Range
    The range between where the person begins to hear sounds and where sound becomes uncomfortable.
  46. Disequilibrium
    Any disturbance of balance
