Product Description

MAICO ERO•SCAN® OAE Screener is an OAE screener for the early detection of hearing loss. This device quickly screens for hearing loss using objective OAE screening technology of measurement by testing the outer hair cells of the ear and providing a Pass/Refer response. The smaller design and accessories allow for easy portability and ease of use. Perfect for any age group but recommended for all children aged 3 years and under. OAE screening is also appropriate for children over 3 who are unable to follow the instructions or complete the tasks required for Pure Tone screening.


  • DP 4 frequency: 2.0, 3.0, 4.0, 5.0 kHz
  • Lightweight, 1.00 oz
  • Battery life good for 15 hours of continuous testing or a minimum 1,000 tests once charged
  • Improved probe design
  • High noise immunity: unlike most OAE’s, the device can be used in noisier environments
  • * Stores up to 250 patient results
  • Includes a probe removal tool and blue colored probe tubes.

Technical The digital signal processor in the instrument generates two pure tones (f1 and f2) through a digital-to-analog converter. These tones are presented to the ear via speaker tubes located in the probe. A microphone in the probe measures the sound in the ear canal and transmits the signal to the analog-to-digital converter. The digital signal processor then filters the signal into narrow frequency bands, and detects any emissions present. The level of these emissions can be compared with the average level of the noise in adjacent frequency bands. An emission is judged to be present when the level in the emission band is 5 db or more above the level in adjacent bands. (The actual pass-fail criterion used in the EroScan instrument uses a more sophisticated statistical test).

Faq Q: What does a REFER result mean?
A: Test results are either PASS or REFER. REFER means that the patient did not pass the test. This could be due to many reasons including ear wax, middle ear fluid, noise, improper test technique or hearing loss. All REFER results should be immediately repeated. If the test result continues to be REFER, the patient should be screened using pure-tone testing and tympanometry. If passing results are not achieved on these tests, then a referral to an audiologist and/or physician should be made.

Who Can Be Screened:

Q: What ages can be screened with the EroScan?
A: Newborn to adult.

Q: Can I test patients with pressure equalization (PE) tubes?
A: Patients with PE tubes can be tested by bypassing the auto-start function of the unit. This is accomplished by first inserting the EroScan with an appropriate ear tip into the ear canal and obtaining a proper seal. To disable the auto-start, at the main menu select the ear to be tested by holding down the right or left arrow keys for 3 seconds until the green "test" light turns off. Once the key is released, the EroScan will calibrate and test as before.

Q: If a patient's ear is impacted with wax can I still screen her?
A: No, impacted wax will yield a refer result. In addition, any significant amount of wax can potentially cause a refer result.

Q: Can a patient with otitis media still be screened with the EroScan unit?
A: Middle ear fluid will yield a refer result. This should then be followed up with pure tone testing and tympanometry so you can determine if there is otitis media based on the flat tympanogram.


Q: Does the unit need to be calibrated?
A: Equipment is not user repairable. Repairs and battery replacement must be performed by a qualified service representative only. Annual calibration is recommended.

Q: How do I clean my EroScan unit?
A: The instrument and its accessories may be wiped clean with a damp cloth using a mild antiseptic solution (e.g. cetylcide). Take care not to put excessive pressure on the clear display window or allow any utensil to puncture the display window or keypad. Do not allow any fluid to enter the device. Do not immerse the instrument in fluids or attempt to sterilize the instrument or any or its accessories. Probe tips should be replaced when they become clogged. Replacement probe tips are included with the instrument. Do not attempt to clean the probe tips, they are disposable and must be replaced when they become clogged.
