    AMTAS PRO

    DIAGNOSTIC AUTOMATED AUDIOMETRY

    GSI AMTAS™, or Automated Method for Testing Auditory Sensitivity, is a patient-directed evaluation tool that uses patented test methods and accuracy algorithms to obtain diagnostic or screening audiometry. With over 15 years of research and development, the validity of AMTAS has been proven through comprehensive studies. AMTAS was created as a resource for clinicians to help manage their busy schedules and promote an efficient office environment. GSI AMTAS automated audiometry is performed independently by patients. This allows clinicians the ability to spend more time focused on patient care.

     

    AMTAS Pro™ operates with a GSI audiometer, either the AudioStar Pro™ or Pello™, that is connected to a computer or touch screen monitor. This version offers diagnostic testing for air and bone conduction with masking and speech SRT, WRS with masking. AMTAS Pro provides up to nine quality indicators and two reporting options. A basic pure tone screening module is also available with AMTAS Pro.

     

    This test is self-paced, typically takes 15 - 20 minutes to complete, and requires minimal supervision. This provides audiologists the opportunity to see more patients and to perform other tasks in the clinic.

FREQUENTLY ASKED QUESTIONS

Q. How does the GSI AMTAS Pro fit into my current practice?
A. AMTAS Pro was created by audiologists, for audiologists. Therefore, it is designed to save time and improve efficiency in a busy clinical office, school, or telehealth setting. It fits well in any practice that does routine audiometric testing. In environments such as ENT offices, VA clinics, private practices, and dispensing offices, AMTAS Pro can be used to obtain validated test results to the audiologist so they can spend more time connecting, counseling, and focusing on patient care.

Q. What equipment do I need to use AMTAS Pro?
A. AMTAS Pro requires the use of an approved GSI audiometer (the AudioStar Pro or Pello), a compatible computer, a bone conductor with AMBANDS for forehead placement, and circumaural (DD450, HDA280) headphones. A USB cable is required to connect the audiometer to the computer.

Q. How long does the testing take on AMTAS Pro?
A. AMTAS Pro is self-paced so patients may proceed at a rate that is comfortable for them. Typically, a full diagnostic evaluation will take 15 - 20 minutes to complete. AMTAS is configurable, so it is possible to perform only air conduction thresholds or a basic air conduction screening which would significantly decrease test times.

Q. How can I be confident in the testing results?
A. AMTAS Pro assigns up to nine quality indicators to provide insight into the behavior of the patient during the test and aides in interpretation. AMTAS methodology and validity has been documented with over 15 years of research and publications in international peer-reviewed journals.

MORE TIME FOR:

  • An audiologist greeting a patient

    WALK-IN PATIENTS

    In a busy practice, AMTAS helps the clinician manage multiple patients at the same time. With automated audiometry, basic diagnostic testing can be completed with one patient using AMTAS while the clinician coordinates care for other patients.

  • An audiologist examining and cleaning hearing aids

    CLEANS AND CHECKS

    When patients return for an annual hearing evaluation, the clinician can get them started on AMTAS while a clean and check of hearing aids is completed.

  • An audiologist counseling a patient after an audiology examination

    PATIENT COUNSELING

    While one patient completes an automated audiometry test with AMTAS, the clinician can meet with another patient to counsel them on their hearing test results, adjust their hearing aids, or answer any other questions that they may have.

The diagnostic and screening tests are self-paced so patients may proceed in the software at a rate that is comfortable for them. Feedback is provided to the patient that helps them distinguish between test tones and other auditory sensations. Clinicians can feel confident that patients will be able to complete the self-paced test with limited supervision.

QUALITY INDICATORS

The quality indicators provide information about the patient's behavior during testing. Using the quality indicators gives the clinician insight on how to proceed with counseling and additional testing.

  • 1. PREDICTED ACCURACY

    Overall rating of the patient's evaluation, or reliability. Good, fair, poor. If poor, a clinical interpretation of the quality indicators is required to determine whether or not a reassessment is needed.

  • 2. PREDICTED AVERAGE ABSOLUTE DIFFERENCE

    Difference between automated and manual thresholds.

  • 3. MASKER ALERTS

    Thresholds where masking may have been too high or too low.

  • An audiogram generated by GSI AMTAS Pro
  • 4. TIME PER TRIAL

    The average time it took the patient to respond to the stimulus.

  • 5. FALSE ALARM RATE

    The number of times the patient responded "yes" when no stimulus was presented, divided by the total number of times no stimulus was presented.

  • 6. AVERAGE TEST-RETEST DIFFERENCE

    Average difference between 1 kHz test and retest in both right and left ears.

  • 7. QUALITY CHECK FAIL RATE

    Number of times patient did not respond to stimulus above threshold, divided by number of measured thresholds. Ensures reliable tests and can assist in identifying functional hearing loss.

  • 8. AIR/BONE GAPS > 35 DB

    The number of air/bone gaps that exceed 35 dB.

  • 9. AIR/BONE GAPS < -10 DB

    The number of air/bone gaps that are less than -10 dB.

Audiologist Counseling Patients

REPORTING

Clinicians have two separate reporting options: a data-centric view where results may be interpreted by the examiner (pictured above) and a text-centric report that the patient can bring home. The Audiologist Report captures the quality indicators, classification, and audiometric data for a detailed look at the hearing test results while the Patient Report features a comprehensive and easy-to-understand interpretation of the audiometric findings.

AUDIOGRAM CLASSIFICATION

After the data is gathered, AMTAS has a patented method of classification of audiometric findings, called AMCLASS, that will help summarize the audiogram based on configuration, site of lesion, and severity. This will give further insight to the clinician on how to proceed with counseling and additional testing, if needed.

  • AMTAS Flex and AMTAS Pro automated audiometry solutions from Grason-Stadler

TWO VERSIONS AVAILABLE

With two versions of AMTAS, audiologists can pick the option that works best for their clinical needs. Along with AMTAS Pro that offers a full range of air, speech, and bone conduction testing, GSI offers AMTAS Flex, a portable version of AMTAS Flex that offers air conduction threshold testing as well as a basic hearing screening module.

AMTAS Flex Tablet Audiometry from Grason-Stadler

AMTAS FLEX

AMTAS Flex is a stand-alone test that uses a tablet with no audiometer required. AMTAS Flex offers threshold air conduction audiometry and screening. Threshold testing obtains pure tone thresholds in about 5 - 10 minutes. The threshold test provides up to six quality indicators and two reporting options. The screening test typically takes 1 - 2 minutes to complete and provides a pass or refer result.
