Tympanometry

If Tymp is selected on the main menu by inserting the probe in ear EV will be displayed and "ready" status is shown on screen . pressing start will preform the test. Beside the tympanogram, EV compliance, gradiant and middle ear pressure will be calculated & displayed. To test next ear you must choose right or left or you can repeat the test again.
Graph Scale, pump speed and pressure range can be defined in setup menu. If manual mode selected pressure can be controlled by dial and pressing "record" will draw the graph

Reflexometry
If reflex is selected the test will begin by start key. Defined frequencies will stimulate the ear for 0.8 second at 70dBHL and its intensity will increment till reflex is detected or reached to the
maximum output. Ipsi and Contra outputs are available for reflex and pure tone or noise signals (LP, HP, WN) can be used as stimulus for both. Also non acoustic reflex is available in NAR mode. Reflex test can be preformed manually by operator and tests like reflex decay are accessible in manual mode.

ETF
Eusachian Tube Function for both non perforated eardrums (Williams) as ETF1 and perforated eardrums (Toynbee) as ETF2 can be tested in Automatic or manual mode

Audiometry
8 frequencies from 250 to 8kHz with Intensity range of 0 to 120dB in 5dB or 1dB step is available and the audiogram will be displayed on the LCD panel by storing thresholds. The results can be stored for both ears on one page

High probe tone
Three probe tones can be used for both tympanometry and reflexometry. 226Hz for normal ear volumes 0.2 to 5ml 687Hz and 1kHz for infants and small ear volumes up to 2ml. Best results for high probe tones are achieved on 0.1 to 0.5ml ears

Computer connection
AZ95 can be connected to PC by USB or Com port. The software can create a database of patients and save and analyze all graphs and test results. Also you are able to online view, type report and print the test results.
