Does the GSI AudioStar Pro require a computer to operate?

No, the AudioStar Pro can operate as a fully functional, stand-alone audiometer without a computer.

What special tests are available on the AudioStar Pro?

QuickSIN, BKB-SIN, TEN Test, ABLB, SISI, AZBio (pediatric and adult), Tone Decay, PI-PB, Stenger, and single and multisyllabic speech normative curves. The Speech Intelligibility Index is automatically calculated.

Can I connect a VRA system to the AudioStar Pro?

Yes, VRA systems may be connected to the AudioStar Pro with 1/8” stereo audio plugs. The electrical specification for the connection is defined in the service manual or by contacting your distributor.

Can I connect a new AudioStar Pro to an existing EMR solution?

Yes, a report may be generated from GSI Suite in multiple formats such as PDF, XPS, TIFF, and JPG that can be attached to EMR programs. It is possible for an EMR provider to write a direct interface using the GSI provided Instrument Services.

Can I create a full report on the AudioStar Pro?

A report can be printed directly from the AudioStar Pro. To enter patient demographic information or comments, a dedicated wireless or USB keyboard is used. For a customized report, audiometric data is transferred to GSI Suite.

Predict your patient’s aided speech-in-noise ability with the Audible Contrast Threshold, or ACT™ test, available on the GSI AudioStar Pro™. The ACT test will take the speech-in-noise data and compare it to the normative data, providing important feedback to the clinician when counseling patients on how to cope in noisy environments.


  • AudioStar Pro Audiometer Features Output


    True 2 channel testing, including simultaneous testing with different transducers in separate channels, along with independent store buttons, masking level indicators, and fast transitions between test types makes the AudioStar Pro more efficient than ever. Eliminate the need to manually calculate SII or PTA. Quickly compare pure tone thresholds and speech audiometry to determine reliability of the patient responses.  

  • AudioStar Pro Audiometer Features Familiar


    In order to effectively evaluate every patient, familiarity with audiometry equipment is essential for every clinician. With the recognizable control panel, intuitive display, single button, single function front panel navigation, clinicians will feel an immediate connection with the audiometer and be able to quickly and accurately test with confidence. 

  • AudioStar Pro Audiometer Features Preferences


    Personalize facility preferences through the configuration application. Test type buttons, digital word lists (.WAV files), power up preferences and other options ensure the AudioStar Pro will enhance every facility's testing and reporting needs by adding efficiency and consistency. 

An audiologist testing a patient


The AudioStar Pro provides the flexibility of a stand-alone audiometer that offers seamless data transfer to a computer. In the event of a network failure or computer lock-up, you will not lose patient data or the ability to test.



    Seamlessly transfer data from the audiometer to a computer. In the event of a network failure or computer lock up, patient data is stored and audiometric testing may be continued without interruption. 


    Features such as speech auto play, auto advance, and auto frequency selection allow the examiner to improve productivity and patient flow. Configure your digital word lists for reliable recorded speech testing.


    Pediatric audiologists can move quickly between warble, pulsed, and pediatric noise for the hearing evaluation to keep the child on task.

    Expedite the data entry and hearing test administration by using the external keyboard and mouse to enter patient demographics and session comments. Print a complete hearing loss report directly from the audiometer to a connected printer or USB flash drive.


    Configurable tests and preferences to improve workflow and optimize speed of testing. Select audiometer preferences such as start up test, auto Hz advance, and wordlist favorites.


    High resolution frequency testing allows users to perform inter-octave testing with eleven options, from half octave to single frequency.

  • Pure Tone Audiometry Testing Screen


    Pressing the Tone Test Type button prepares the AudioStar Pro for pure tone audiometry (air and bone conduction) testing from 125 to 8000 Hz. Each selection on the blue navigation menu of the audiometer is specific to Pure Tone Testing. It is possible to utilize headphones (DD45), insert earphones (ER3A, IP30), bone vibrators (B71, B81), and sound field speakers from this test type. Pressing this button will set the defaults from the configuration application to start the test.

  • Full frequency


    Pressing the High Hz test type button prepares the AudioStar Pro for high frequency air and bone conduction testing from the high range (8000 to 20,000 Hz) or the full range (125 to 20,000 Hz). Select full or high range from the blue navigation menu. It is possible to utilize the high frequency headphones (HDA 200/300), bone vibrator (B71, B81), and sound field speakers from this test type. Pressing this button will set the defaults from the configuration application to start the test.

  • Speech Audiometry Testing Screen


    Pressing the Speech Test Type button prepares the AudioStar Pro for speech testing. The AudioStar Pro comes with over 100 integrated wordlists for repeatable and reliable recorded speech testing. Auto play and auto score may be implemented for ease of testing. Mouse control allows you to present, pause, repeat, skip, and score with ultimate ease, removing the main objection for recorded speech testing. Other speech-in-noise tests and word lists can be loaded on to the audiometer directly from a USB drive.

  • Speech-in-Noise Audiometry Testing Screen


    The primary complaint of hearing-impaired persons is difficulty in background noise. The measurement of SNR loss (signal-to-noise ratio loss) is important because speech understanding in noise cannot be reliably predicted from the pure tone audiogram (Killion & Niquette, 2000). A list of six sentences with five key words per sentence is presented in four-talker babble noise. The sentences are presented at pre-recorded signal-to-noise ratios, which decrease in 5 dB steps, from 25 (very easy) to 0 (extremely difficult). The SNR’s used are 25, 20, 15, 10, 5, and 0, encompassing normal to severely impaired performance in noise.

A clinician reviewing audiometry testing results

Audiometric results are easily transferred from the AudioStar Pro 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.
