BROCHURE

  • Pure Tone Audiometry Testing Screen

    PURE TONE

    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

    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

    SPEECH

    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

    QUICKSIN

    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.

    Maximizing Work Flow

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.
