Intended Use The AudioStar Pro is intended to be used for the identification and etiology of hearing loss in patients of any age. It is intended to be used by an audiologist, ENT, hearing healthcare professional, or trained technician in a hospital, clinic, healthcare facility or other suitable quiet environment as defined in ANSI S3.1 or...
GSI AudioStar Pro™ Clinical Audiometer Audiometric Standards The AudioStar Pro is designed to meet or exceed the following standards: Audiometer Standard Requirements - Type 1 1. ANSI S3.6 (2010) Specification for Audiometers (Type 1) 2. IEC 60645-1 Electroacoustics - Audiological Equipment - Pure-Tone Audiometers Type 1 3.
Warnings, Cautions, and Errors The GSI AudioStar Pro Clinical Audiometer is designed to be used with a hospital grade outlet. Injury to personnel or damage to equipment can result when a three-prong to two-prong adaptor is connected between the GSI AudioStar Pro power plug and an AC outlet or extension cord.
GSI AudioStar Pro™ Clinical Audiometer The CAUTION label identifies conditions or practices that could result in damage to the equipment. NOTE: Notes help identify areas of possible confusion and avoid potential problems during system operation. Status/Error Messages Please try another selection: Indicates an incorrect selection. This could include actions such as incompatible transducers, incompatible routing, or no calibration data stored for the selected transducers.
Elimination of Ambient Noise The GSI AudioStar Pro may be installed in a single room environment or as part of a two room suite. Excessive noise in the test environment, such as that produced by conversation, office equipment, or printers, reduces test validity because it tends to mask the test signals.

GSI AudioStar Pro™ Clinical Audiometer More Test Type ABLB In ABLB (Alternate Binaural Loudness Balance) test the tone is presented alternately between the two ears. The level of the tone stays the same in one ear (i.e. fixed ear) and is varied up / down in the other ear (i.e. variable ear).
BKB-SIN The BKB-SIN is a speech-in-noise test that uses BKB (Bamford-Kowal-Bench) sentences, recorded in four-talker babble. The BKB-SIN can be used to estimate SNR loss in children and adults for whom the QuickSIN test is too difficult. The BKB-SIN display has the Title bar and the Channel 1 and 2 Output sections that are similar to what has been described for the speech displays.

NOTE: A total of six (6) individual speech test results may be stored for each ear. Right ear results will be stored in the left column, left ear results will be stored in the right column and binaural results will typically be stored in the left column.
GSI AudioStar Pro™ Clinical Audiometer Threshold Determination (Pure Tone): Modified Hughson-Westlake Present the tone at 50 dB. Present the tone for 1 or 2 seconds. The time between the tones should vary, but should not be shorter than the test tone.
Spondaic Speech Testing, Speech Reception Threshold (SRT) Speech Reception Thresholds (SRT) refer to the intensity level at which a patient can repeat 50% of the presented words correctly. Use the following instructions to prepare the patient: “You will now hear some two syllable words such as hotdog, ice-cream, baseball, mushroom or toothbrush.
GSI AudioStar Pro™ Clinical Audiometer Special Test Procedures - More Test Type button The AudioStar Pro may be configured to perform many audiologic evaluations for further diagnosis, to rule out the presence of malingering and for research purposes. This section describes special test procedures that have been optimized for use with the GSI AudioStar Pro audiometer.

The AudioStar Pro uses configuration application software to define the instrument and test settings defaults. These settings are downloaded from the application software on the PC to the AudioStar Pro. It is recommended that a copy of the custom configuration is saved as a back-up. This will allow the custom configuration to be loaded quickly onto multiple AudioStar Pros.

Log Tab In the event of a repeatable error, the log window allows the examiner to upload or email a file from the AudioStar Pro to the computer. This file “retraces your steps” (button pushes) for the purposes of troubleshooting.
BKB-SIN and QuickSIN tests. Norm Values Tab The GSI factory does not include sample norm values to be used on the Speech Audiogram screen. Each facility should enter its own values, if desired. If Display on the AudioStar Pro box is checked, the normative curves will appear on the Speech Audiogram screen based on the transducer being used.
GSI Suite GSI Suite Audiometric Data Management software (Rev. 2.0 and higher) is compatible with the GSI AudioStar Pro as well as legacy products. GSI Suite imports, saves, and stores audiometric data from the AudioStar Pro and allows the addition of comments into a report. The report data is saved in a PDF or other format that may be saved to the local PC, a remote location or attached with electronic medical data records (EMR).
With extended use, all transducer cords tend to fray internally at the connectors. To evaluate the cord status, turn on the GSI AudioStar Pro. Set the HL to a comfortably audible level. Place the transducer on your head. Activate both Interrupt buttons.
GSI AudioStar Pro™ Clinical Audiometer earphones are at fault and should be replaced. In any case, the audiometer should be scheduled for immediate maintenance. Speech Level Check To check the speech level with recorded speech, select the Speech test type button.
Cleaning and Disinfecting Agents According to the recommendations from the CDC, audiometric equipment is considered to be non-critical medical equipment and typically requires cleansing followed by low to intermediate level disinfecting, depending on the nature of the contamination. Cleaning should be done with a mild soapy detergent (such as dishwashing liquid) and a damp cloth or an Endozime Sponge followed by an application of EPA-registered hospital disinfectant.

AudioStar Pro. Install and operate the GSI AudioStar Pro according to the EMC information presented on this page and the next 4 pages. The GSI AudioStar Pro has been tested for EMC emissions and immunity as a standalone instrument. Do not use the GSI AudioStar Pro adjacent to or stacked with other electronic equipment.
Guidance and Manufacturer’s Declaration - Electromagnetic Emissions The GSI AudioStar Pro is intended for use in the electromagnetic environment specified below. The customer or the user of the GSI AudioStar Pro should assure that it is used in such an environment.
Guidance and Manufacturer’s Declaration - Electromagnetic Immunity The GSI AudioStar Pro is intended for use in the electromagnetic environment specified below. The customer or the user of the AudioStar Pro should assure that it is used in such an environment.
To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the AudioStar Pro is used exceeds the applicable RF compliance level above, the AudioStar Pro should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the AudioStar Pro.
