Transient Evoked Otoacoustic Emissions (TEOAE)
Trusted by clinicians for more than ten years:
• Able to screen for even a mild hearing loss
• Testing frequency range: 1.5 to 3.5 kHz

Distortion Product Otoacoustic Emissions (DPOAE)
• Frequency specific screening: 2, 2.5, 3.2, and 4 kHz

AABR® Technology
Binomial statistics signal detection, the same method used with the ALGO® Newborn Hearing Screener:
• Necessary for detecting auditory neuropathy1
• Optimized for screening newborns
• Testing frequency range: 2 to 4 kHz

Performance validated in numerous clinical studies1:
• High sensitivity and specificity
– minimizing false pass and false refer results

Robust signal detection
• Artifact rejection system distinguishes between external noise and actual patient response
• Fast test times
– TEOAE averages 20 seconds
– DPOAE averages 30 seconds
– AABR technology averages 2 minutes

• 17-key design provides convenient entry of patient information
> Multiple T (TEOAE), D (DPOAE), and A (AABR) technology combinations available
> Included Natus data management software allows data transfer to a PC
• 5-key design provides simple screening with no data entry
> TEOAE or DPOAE technology options are available
> Natus data management software allows transfer of results to a PC
• Ideal for one or two-step screening protocols
• Meets JCIH, AAP, and NCHAM requirements for surveillance screening of newborns and infants.

• Reduces the number of repeat tests
• Eiminates unnecessary follow-up and tracking

• Graphic display shows statistical result pattern
• Keypad allows fast data entry
• Ear probe is lightweight and easy to clean
• Battery is exchangeable – provides approximately ten hours of testing
• Many language options are available

• Minimizes risk of user error and test variability
• Reduces training time for new users

• Echo-Screen Plus (17-key) configuration:
> Stores up to 250 screening records
> Wireless printing of screening results
> Data transfer to and from a PC via Natus data management software
> Export compatibility with a variety of third party data management systems
• Echo-Screen Basic (5-key) configuration:
> Stores up to 50 screening records
> Printing of screening results via serial cable
> Transfer of screening results to a PC via Natus data
