How many types of ear machines are there?
There are two main types of hearing aids: Analog hearing aids convert sound waves into electrical signals and then make them louder. They’re usually less expensive and have simple volume controls. Digital hearing aids convert sound waves into numerical codes similar to computer codes, then amplify them.
What is REUG?
Real Ear Un-Aided Gain (REUG) – this step is the first to be performed when the probe microphone has been positioned in the ear. It is purely a measurement of the ear canal without any Hearing Device applied and shows the patients ear acoustics.
What Is REM in audiology?
Real Ear Measures (REM) Real ear measurement (REM) is critical when fitting patients with hearing aids because it verifies the gain (volume) provided by the hearing aids based on the pitch and volume of the sound they pick up.
What is Reig audiology?
REIG: Real Ear Insertion Gain. The difference between aided and unaided ear canal SPL (REAR-REUR=REIG). REIG is a calcu- lated difference measurement. REOR: Real Ear Occluded Response. The SPL, across frequencies, measured in the ear canal with a hearing aid inserted and OFF, for a given input signal.

What is pocket model hearing aid?
Pocket Model : Worn in a pocket or harness at chest level. It consists of the body of the hearing aid containing the microphone, amplifier and controls. A cord transmits the electrical output to a receiver, which converts this signal into sound. The receiver is attached to a mould, which holds it in place.
What is 2cc coupler?
The HA-1 is a 2cc coupler designed for measurement of custom-molded hearing aids, and is the Standard ANSI coupler. They have a physical appearance that represents traditional BTE hearing aids, but their fit in the ear canal presents a residual volume closer to that of a CIC hearing aid.
What is a Verifit?
VerifitLINK™ Verify and adjust hearing instruments to target automatically through a direct interface with the fitting software. Ensures an objective verification against clinically-validated targets. Provides accurate target match equivalent to manual methods in significantly less time**
Why do we measure ear measurement?
Real-ear measurements are important because they measure how a hearing aid’s intensity (volume) and frequency response (pitch) are affected by your ear. The results are hearing aid settings that are best suited for the size and shape of your ear and for your hearing loss.
What are the different types of middle ear instruments?

What are the different types of sound level meters?
There are two types or classes assigned to sound level meters: type 1 / class 1 or type 2 / class 2. For assessing noise in basic industrial, commercial, educational, recreational or residential applications, a type 2 / class 2 sound level meter usually will suffice.
What are the instruments used in sound measurement?
SOUND MEASURING INSTRUMENTS. 1 the transducer; that is, the microphone; 2 the electronic amplifier and calibrated attenuator for gain control; 3 the frequency weighting or analyzing possibilities; 4 the data storage facilities; 5 the display.
What kind of instruments are used in ENT?
Specialty surgical instruments are used in ENT procedures such as myringotomy, tonsillectomy, adenoidectomy, mastiodectomy, turbinate, tympanoplasty, implantations, tracheotomy, septo rhino, and stapedectomy. Popular instruments include: Cannulas and Suction Tubes.
