Description of Function
OAE hearing screener is used to precisely and objectively screen for hearing loss and to
determine cochlear status in new born, infants, toddlers, children & adult.
Operational Requirements
It shall be portable and battery operated device.
System Configuration
Otoacoustic Emission (Screening unit) OAE (DP and TE), complete unit with complete
accessories.
Technical Specifications
Hearing screener for measurement of OAE by DPOAE and TEOAE tests
It shall be hand held, lightweight unit.
It shall perform fast automatic tests.
Screener should be integrated with evoked otoacoustic emissions (OAE) and auditory brainstem
responses (ABR) into a single, portable screening device.
The device shall be self- contained with diagnostic features, to test new born, children, adults, the
elderly and all difficult- to- test patients.
TEOAE (Transient Evoked Otoacoustic Emission):
 Frequencies: approx. 1.5 to 4 kHz
 Sample rate: 16 kHz
 Stimulus level: ca. 80 dB SPL peak
 Stimulus type: Nonlinear click
 Statistical stop criterion (TE Quick) or user defined
 Stop criterion (SNR: 3, 6 or 9 dB) in 3, 4, or 5 out of frequency bands (1.5, 2, 3, 4 kHz)
(TE diagnostic.)
 Window of analysis: 5-13 ms post stimulus.
DPOAE (Distortion Product Otoacoustic Emission):
 Frequencies: 2 to 5 kHz
 Sample Rate - 24kHz
 Frequency ratio f2/f1: 1.2
 Level ratio L2/L1: Scissor Paradigm
 Measurement Interval- 512 samples
 Frequencies f2: 2, 3, 4, 5, kHz (single & multiple selections possible)
 Stimulus level L2: 35 to 65 dB HL (in steps of 5dB)
Stimulus intensity: 40 to 70 dB SPL (DPOAE). 83 dB SPL (TEOAE).
Maximum output (Protection): 90 dB SPL.
Microphone system noise:
 -20 dB SPL @ 2 kHz (1 Hz bandwidth).
 -13 dB SPL @ 1 kHz (1 Hz bandwidth).
It shall have multiple test methods.
It shall have data storage memory for 250-300 tests.
It shall have facility for data transfer to PC via USB or wireless
Shall have facility to print data through thermal printer as well as through external printer.
Display: LCD or LED type.
