Introduction GSI AMTAS Pro™ is a software program that provides an automated method for obtaining a diagnostic hearing test including air and bone conduction thresholds with masking applied to the non-test ear. GSI AMTAS Pro also provides automated tests of speech reception. Both Speech Recognition Threshold (SRT) and Word Recognition Scores (WRS) may be obtained. AMTAS was developed through a partnership between Audiology Incorporated and three research institutions, the University of Minnesota, the University of Utah, and the James H. Quillen Veterans Administration Medical Center. The development was funded by the National Institutes of Health Small Business Technology Transfer (STTR) Program. AMTAS Pro is based on a psychophysical procedure that uses the patient’s responses to determine signal levels needed to find auditory thresholds. Once the transducers are placed on the patient, the test is self-administered. The test is selfpaced so that patients proceed at the rate that is comfortable for them. Feedback is provided to the patient that helps them distinguish between test tones and other auditory sensations. GSI AMTAS Pro was designed to provide the same test results that would be obtained by an expert audiologist with a psychophysical procedure that has advantages over the commonly used clinical (“HughsonWestlake”) method. Quality indicators provide information about the validity of results. Air conduction audiograms are classified based on configuration, severity, and symmetry. The program generates a report and interfaces with GSI Suite and the data may be transferred to other software programs. The software performs these tests by controlling a GSI audiometer connected to the PC running the software.
Indication for Use of GSI AMTAS Pro GSI audiometers are 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.
Intended Use of GSI AMTAS Pro GSI AMTAS PRO is intended to be used to obtain diagnostic audiometric data through a GSI audiometer. It is intended to be used for routine clinical testing in any environment in which pure-tone audiometry and speech recognition testing is performed. Anyone who can follow the instructions used for manual audiometry may be tested by GSI AMTAS Pro. Patients unable to cooperate because of young age or other conditions that cannot undergo pure tone audiometry and may need to have the auditory system tested by other methods.
Installation and Setup Precautions The following precautions will aid in the secure collection and storage of patient data: • Disable the “suspend USB” power option to ensure proper communication between instrument and PC. • To avoid unwanted data transfer from PC to the network, ensure that an appropriate virus & spyware scanner is installed, updated, and effective. Please contact a local administrator for help and guidance. • All users should have a unique login to the PC. NOTE: To ensure proper sound presentation all speaker enhancements in Windows should be disabled. The Sound Playback - Speaker Properties dialog, Enhancements tab has the option to disable all enhancements.

Patient Preparation Although the GSI AMTAS Pro is a self-administered test, it is recommended that the transducers be placed on the patient by trained health care personnel. It is also appropriate to provide general instructions to the patient about the test and how to interact with the computer. The patient should be seated comfortably in front of the PC with the GSI AMTAS Pro program running.
Bone Oscillator Placement The bone oscillator should be placed prior to the placement of the headphones. The AMBAND headband should be used to couple the bone conduction vibrator to the head in the forehead position. A Velcro dot (provided with the headband) can be attached to the back of the bone vibrator to stabilize it under the headband. Follow the AMBAND instructions and use the appropriate attachment point based on the age and head size.
Headphone Placement • • • • •
•
Take the headphones and pull both sides out while placing the headband on the very top middle part of the patient’s head. Make sure that the ears are in the center part of the headphone cups. Ensure the headband remains in the middle of the very top of the head The ears should be in the center and completely surrounded by the ear cups. If you need to change the height of the ear cups, take the headphones completely off and adjust by using your thumb and fingers on the yoke and block. Push the yoke and block closer together to reduce the overall ear cup height. Conversely, if you need to increase the height of your headphone ear cups, pull the yoke and blocks apart. Once adjusted, place the headphones back on the patient’s head.
GSI AMTAS Pro Program GSI AMTAS Pro and the GSI AMTAS Pro Config App are installed as part of the software installation. GSI AMTAS Pro is the program that the patient interacts with to obtain the audiometric data. The GSI AMTAS Pro Config App is used by the administrator to set the users of the GSI AMTAS Pro program and the parameters used for the test. The GSI AMTAS Pro Config App also manages the data obtained from the GSI AMTAS Pro program. The GSI AMTAS Pro program operates in full screen, kiosk mode (no other program can be run and the desktop is not available). In order to exit the program and return the computer to the desktop, a password may be required depending on the security type selected during installation. A password may also be required to enter the configuration from the GSI AMTAS Pro program.
NOTE: The GSI AMTAS Pro program runs in kiosk mode preventing most keystrokes from being recognized and preventing the user from leaving the program. However, the Ctrl+Alt+Del key combination is a special sequence that is not trapped by the program. Pressing Ctrl+Alt+Del invokes Windows Security with an interface that allows the user to lock the system, switch user, log off, change password or invoke the Windows Task Manager. The IT administrator should adjust the Window user’s security to deny or allow the options accessible with this key combination.
Launching and running GSI AMTAS Pro After installation of the program, a shortcut icon appears on the desktop. Doubleclick the desktop icon to open GSI AMTAS Pro. It is also possible to open this application from Start > All Programs > Grason-Stadler > GSI AMTAS Pro.
User Interface – Screen Layout and Controls Welcome Screen Once the GSI AMTAS Pro is started, the program presents the Welcome screen in full screen, kiosk mode. The Welcome screen contains a menu icon in the top right corner and a Get Started arrow in the bottom right corner.
Menu Icon
Menu When the menu icon is selected on the opening screen, a list of 3 menu items is presented. When the Settings or Exit menu item is selected, a prompt for a password will appear if security has been enabled. The password should be the Windows password of the user who is currently logged into the PC or the GSI AMTAS admin password depending on the type of security selected at the installation of the software. Once the password has been authenticated, the Settings menu option displays the parameters used for the GSI AMTAS program. Once the password has been authenticated for the Exit menu option, the user is returned to the PC desktop. The About selection will display the version, copyright, patent and trademark information of the GSI AMTAS program.
Get Started Arrow The Get Started arrow is pressed to proceed with the GSI AMTAS Pro testing. The program takes the user to the next screen - the patient registration screen.
Patient Information Screen The patient information screen provides fields for patient information. Required fields are indicated by an ‘*’. The required fields may be set in the configuration program or via the settings menu option. The First Name, Last Name and ID fields have a maximum character limit of 50.
Once the required fields have been entered, the Continue button will become selectable to indicate the test is ready to begin. Pressing the Continue button will move to the next screen. The next screen that is displayed depends on the configuration settings. Options include a headphone check and/or the instructional video or text (see the Setup and GSI AMTAS Pro Config App section of this manual for details). The configuration Test Options also determines the exams that will be performed. Available tests include any combination of air thresholds, bone thresholds, speech recognition threshold and word recognition.
NOTE: The GSI AMTAS Pro Config App provides an option to skip the patient information screen.
Listen for a Tone Screen The “Listen for a TONE” screen is presented to alert the patient that they should pay attention and listen to see if they hear a tone. GSI AMTAS Pro uses this screen for air and bone diagnostic threshold testing as well as screening. There is a progress bar at the bottom of the screen to indicate the percentage of the test that has been completed. Masking is always presented to the non-test ear.
Once the tone has been presented, a new the screen is displayed to allow the patient to respond.
NOTE: Because of the psychophysical procedure that is employed by the program, there may be times in which no stimulus is presented. In addition, if the patient does not respond in a timely fashion, a warning message will be presented. The fourth non-response will result in the application ending the test and proceeding to the Finish screen
Response to a Tone Screen The response screen prompts the user with the question about hearing the tone and presents two icons. The patient indicates that they heard the tone by choosing the icon on the left and to indicate that they did not hear the tone by choosing the icon on the right.
The “Listen for a TONE” and “Did you hear the TONE” screens repeat to test the different levels and frequencies as needed to determine the patient’s threshold. The air conduction threshold test is followed by the bone conduction threshold test (if both tests have been selected in the settings). The screens are the same for the two tests and there is no indication to the patient that the air threshold test has completed and the bone threshold test has started.
Listen for a Word Screen The “Listen for a WORD” screen is presented to alert the patient that they should pay attention and listen to see if they hear a word. GSI AMTAS Pro uses this screen for speech recognition threshold and word recognition scoring. There is a progress bar at the bottom of the screen to indicate the percentage of the test that has been completed. Masking is always presented to the non-test ear.
Once the word has been presented, a new the screen is displayed to allow the patient to respond.
Response to a Word Screen The response to a word screen prompts the user with the question about hearing the word and presents a list of four words from which to choose. The patient indicates that they heard the word by choosing the matching word.
The “Listen for a Word” and “What word did you hear?” screens repeat to test the different levels as need to determine the patient’s threshold. The speech recognition threshold test is followed by the word recognition test (if both tests have been selected in the settings). The screens are the same for the two tests and there is no indication to the patient that the speech recognition threshold test has completed and the word recognition test has started.
