Automated Audiometry

Grason-Stadler is excited to introduce GSI AMTAS™, or Automated Method for Testing Auditory Sensitivity. This is a patient-directed evaluation tool that uses patented test methods and accuracy algorithms to perform diagnostic or screening audiometry. AMTAS software is run through a GSI AudioStar Pro™ or GSI Pello™ that is connected to a touch screen computer.

AMTAS was created as a resource for audiologists to use to help manage their busy schedules and promote an efficient office environment. Most importantly, AMTAS frees the audiologist from time consuming and routine testing to spend more time focused on patient care.

Boost your office efficiency

AMTAS was developed to boost efficiency by providing a reliable and accurate way to obtain a basic diagnostic hearing test, including air and bone conduction thresholds, SRT and WRS. A screening mode is also available that only captures air conduction thresholds.

 

  • Self-directed and self-paced
  • Pure Tone: Air and Bone with masking
  • Speech: SRT and WRS with masking
  • Configurable based on testing needs
  • Nine Data Quality indicators
  • Report Options: Diagnostic and Counseling

A tool that 
saves time

AMTAS is not an audiologist, it is just a hearing test. It is an accurate and reliable hearing test, but still, just a hearing test. This software is a time-saving tool for the audiologist to use for routine evaluations, annual testing, screening and walk-ins.

 

AMTAS frees up more time for

  • AMTAS Walk-Ins

    Walk-Ins

    In a field that continues to get busier, AMTAS allows you to have one patient working through their audiogram, while you can attend to walk-ins and other patients that otherwise may have long waiting times.

  • AMTAS Cleans

    Cleans and Checks

    When your patient returns for an annual evaluation, you can get them started on AMTAS while you clean and check their hearing aids.

  • AMTAS Counseling

    Counseling

    One patient can work on AMTAS, while you meet with another patient to counsel them on their test results, adjust their hearing aids or answer any other questions that they may have.

Comfortable Testing

The test is self-paced so patients may proceed 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.

Nine Quality Indicators

AMTAS is different than other automated tests. It provides nine quality indicators, classification of audiometric findings and two report formats. The nine quality indicators provide information about the patient's behavior during testing. Using the quality indicators gives the audiologist insight on how to proceed with counseling and further testing. The quality indicators are as follows:

  • 1.  Predicted Accuracy

    How accurate is the test? Good, fair, poor. If poor, a re-assessment may be necessary.

  • 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.

  • AMTAS REPORT
  • 4.  Time per Trial

    How long it took the patient to respond to stimulus on average.

  • 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 right and left ear.

  • 7.  Quality Check Fail Rate

    Number of times patient did not respond to stimulus above threshold, divided by number of measured thresholds.

  • 8.  Number of Air/Bone Gap > 35 dB

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

  • 9.  Number of Air/Bone Gap < -10 dB

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

AMCLASS

After the data is gathered, AMTAS has a patented method, called AMCLASS, to classify the audiogram based upon the configuration, severity and site of lesion. Users then have two separate printing options: a data-centric view that may be interpreted by the examiner, or a text-centric report that the patient can bring home with them.

Efficient. Convenient.
Proven.

AMTAS is simple and easy to use. The on-screen instructions are clear and concise for the patient. AMTAS takes about 15-20 minutes to complete and direct supervision is not necessary. AMTAS works, the validity has been proven with comprehensive studies. You can trust this software to be a reliable source of testing information.
