Allows comparison of subject threshold to qualifying average. Comparison of unoccluded thresholds within a session. Indicates compliance with ANSI S12.6 requirements.

Creates test documentation and retrieves prior thresholds from subject for comparison with current thresholds as required by ANSI S12.6.

• Define test type: qualifying subject, training as subject, conducting protector test.
• Subjects are tracked by subject ID for HIPA compliance.
• Document what protector is being tested.
• Load expected attenuation to speed up occluded threshold seeking.

REATPro provides seamless data export to MSExcel based template files that users can customize to meet their own data analysis and reporting needs. Both Unoccluded and Occluded thresholds, as well as the standard deviations of the trace reversal mid points used to derive the threshold are exported. A file header section provides documentation on all test setup parameters. Optionally, users may also export the sound pressure level vs time trace history to MSExcel for detailed analysis of threshold determination time and reversal history.

The Manual / Calibration tab can be used to present and calibrate any stimulus at any level to any or all outputs, continuously or pulsed. This can be useful for subject training, checking that the sound system is functioning and troubleshooting problems.

REATPro provides flexible configuration options to support a variety of data acquisition systems and audiometric testing protocols.

The Output Configuration tab allows you to assign output channels to each channel of the REAT sound system and configure key system settings. Equalization is available for each channel, as well as system wide, in order to generate a uniform sound field and achieve maximum repeatability. REATPro supports relay controlled L-pad attenuators for an extremely low noise floor.

In the Response Switch tab the switch device input is selected. REATPro supports mechanical or optical switches, and can detect if the switch is present and functioning before start of test to prevent runaway noise. There is also an option for the subject to activate fitting noise with the response switch.

The REATPro Stimulus Sequence setup tab allows you to configure the frequencies to be presented and the order in which they will be presented.  Preset frequency lists and presentation orders that meet industry standards are provided for quick configuration of the stimulus sequence. Or use customized stimulus from WAV files and utilize the extended frequency range  (63Hz – 16kHz) to help further your research.

The REATPro Timing and Threshold configuration screen provides complete user control over the audiometric threshold determination parameters associated with the test.  Threshold seeking rates and reversal count settings can be controlled here in order to either reduce time to threshold or increase the accuracy of the thresholds.

Use of prior subject threshold and expected protector attenuation also reduces the time it takes to reach both unoccluded and occluded hearing thresholds

The HL/SPL tab gives the option to report thresholds as hearing level or sound pressure level and makes the conversion as per ANSI S3.6-2010.

The Alarms and Sounds setup screen allows remote operator monitoring of test. The test operator can also configure custom alert sounds for system events and custom noises for fitting and insertion loss measurements, all from user defined WAV files.

Contact us about the Audio Filter Toolkit to generate custom WAV files equalized for your chamber.

The File Locations tab is used to configure how data is saved to a local or network drive. Data can be sorted by subject threshold history, protector testing history, or by study files for specific research or noise reduction ratings.

REATPro configuration settings can be saved and reloaded into REATPro when the application is first started.  This allows the test facility technical manager to optimize the system configuration settings for the unique needs of the laboratory, and then the test technician can simply be taught to retrieve this settings file when REATPro is started.  Configuration files can be password locked to prevent changes by system users.

• Runs in automated manor from first to last frequency.
• Runs both unoccluded and occluded modes.
• Unoccluded mode has max level protections to ensure subject safety.
• Provides level tracking and current threshold info with comparison to prior threshold.
