You may be able to find a list somewhere on the internet, but here are a a few you’ll see here on the forums (in no particular order):
BTE - Behind the Ear (hearing aid style that sits between your head and the top part of your ear.
OTE - Over the Ear (same as BTE)
HA - Hearing Aid
HOH - Hard of Hearing
ENT - This is an MD that specializes in diagnosing and treating medical problems (pathology) that involve the Ear, Nose and Throat.
AuD or Audi - Doctor of Audiology. These are very highly trained medical professionals, who have somewhat less training than an MD. They specialize in testing and evaluating a patient’s hearing, and recommending and dispensing hearing aids.
HIS - Hearing Instrument Specialist (HIS). This is a state licensed professional with education and experience (less education than an AuD) in recommending and dispensing hearing aids. An HIS performs many of the same tasks as an AuD.
CIC - Completely in the Canal. A hearing aid style that sits completely inside the ear canal.
Audiogram - That’s your hearing test, and shows how well you hear different frequency tones.
HF an LF - high frequency (those up around 4khz to 8khz) and low frequency (down around 250Hz to 1kHz). These are the numbers, left to right, on your audiogram. The numbers up and down are in decibels or db. Different people have losses at different points. Take a look at:
RITE (receiver in the ear), CRT (Canal Receiver Technology), RIC (Receiver in the Canal) - Trade names, and all mean the same thing. A hearing aid with the output transducer (the speaker) on a tiny wire actually inside the ear canal. Usually used with a BTE style HA.
Thin Tubes - Not really an abbreviation. Thin tubes are small clear tubes that carry the sound into the ear canal, again with a BTE HA.
Aid - Shortened from Hearing Aid
Instrument - Hearing Aid
TLA - Three Letter Acronym (remember, TLA is a TLA)
Well, that’s not a bad start. OK everyone, chip in with what I’ve missed.
