Choose your preferred features today and upgrade your device with additional features as your audiometry and tympanometry needs change in the future.

  • GSI 39 Features Flexible

    MULTIPLE CONFIGURATIONS

    Accommodate a variety of testing needs with five versions. Combine tympanometry, ipsi and contra reflex screening, and screening audiometry to quickly assess middle ear function, neural integrity, and hearing level in patients of all ages.

  • GSI 39 Features Reliability

    RELIABILITY YOU CAN TRUST

    GSI has a history of manufacturing products that are designed for durability. Enjoy the flexibility of a portable, stand-alone device with an internal printer or connect to a PC for seamless EMR/EHR transfer.

  • GSI 39 Features Automatic

    TESTING TAKES SECONDS

    Soon as the probe tip obtains a seal in the ear canal, the tympanogram will automatically begin. Pressure sweep is 600/200 daPa per second which provides a fast and accurate picture of the middle ear function.

FREQUENTLY ASKED QUESTIONS

Q. When would you use the pure tone signal modifications, steady, pulsed, and FM on the GSI 39?
A. These can be used in a number of screening situations. In a school screening environment, the operator can test a distracted child with a variety of interesting test stimuli. In an industrial screening environment, the operator can present a signal that allows the patient to distinguish the signal from “ringing” in the ear.

Q. How does Auto Start operate with the tympanometry module?
A. The tympanogram will automatically begin recording as soon as ear canal is sealed with a probe tip. This is a large benefit for the examiner that may need both hands to work with the patient, acting as an assistant.

Q. What type of printing formats are available with the GSI 39?
A. There is an on-board printer that will print the tests in the order they were obtained. It is possible to add a standard sized printer for direct printing to a regular piece of paper. Additionally, you may transfer the data to GSI Suite and print the data on a customized report.

Q. Is 1000 Hz probe tone available on the GSI 39?
A. Yes, you may add the 1000 Hz probe tone to any version of the GSI 39.

Q. What are the five versions available with the GSI 39?
A. • Version 1 - tympanometry alone and tympanometry plus screening ipsilateral acoustic reflex testing
• Version 2 - tympanometry alone and tympanometry plus ipsilateral and contralateral screening acoustic reflex measurements
• Version 3 - tympanometry alone, tympanometry plus ipsilateral and contralateral screening acoustic reflex measurements, and screening audiometry, both manual and automated
• Version 4 - tympanometry alone, tympanometry plus ipsilateral acoustic reflex screening testing, and screening audiometry, both manual and automated
• Version 5 - tympanometry only

2 SCREENING OPTIONS

A special "combo" probe is an available option with all versions that combines both 226 Hz and 1000 Hz measurement capability. Both infant and adult normative ranges may be selected as a guide on the display and printouts.

KEY DEVICE FEATURES 

  • 1. MULTIPLE PROBE TONES

    Probe tones of 226 Hz and 1000 Hz are available. Normative ranges for middle ear pressure and admittance are included.

  • 2. SCREENING AUDIOMETRY

    Air conduction screening from 125 to 8000 Hz. Steady, Pulsed, and FM provide a variety of interesting test stimuli to accommodate all screening environments.

  • 3. FIVE VERSIONS AVAILABLE

    Flexible options that include tympanometry at 226 Hz, 1000 Hz, ipsilateral and contralateral reflex screening, and audiometry in any combination.

  • GSI 39 Audiometer Tympanometer Features
  • 4. IPSI AND CONTRA REFLEX SCREENING

    Quickly screen for the presence of ipsilateral or contralateral acoustic reflexes at up to four frequencies.

  • 5. STAND-ALONE, PC ENABLED

    Have the reliability of a stand-alone device with the ability to be EMR/EHR compatible. A single button press transfers tympanometric and audiologic data for advanced reporting options.

  • 6. PRINTING OPTIONS

    Use the on-board printer on the combined audiometer and tympanometer or connect to GSI Suite to print results.

EMR MADE EASY

With one button press, test results are transferred from the GSI 39 to GSI Suite software where audiometric, tympanometric, and OAE test results may be combined into a single comprehensive report. Counseling overlays such as the speech banana or hearing loss levels assist the clinician with explaining the results to the patient and family members.
