REATPro Real Ear Attenuation at Threshold Software

REATPro is our third generation software application for use by hearing protector professionals. REATPro conducts Real Ear Attenuation at Threshold (REAT) audiometric measurements in accordance with the ANSI S12.6, ANSI S3.19 and ISO 4869-1 standard test methods on earplugs, earmuffs and other hearing protection devices and systems. Plus, when used in conjunction with our Trident software, REATPro also supports many other measurements commonly conducted in hearing protector test laboratories, including MIRE and fixture based testing of hearing protectors. REATPro operates on National Instruments PXIe-4463, PXIe-4464 and PXI-6220 series hardware. REATPro is an automatic Bekesey audiometer program designed to provide stimulus and track responses for sound field hearing threshold determination for both occluded and unoccluded conditions. REATPro also provides calibrated signal generation for MIRE and fixture based tests.

 

Features:

  • Tracks both unoccluded and occluded hearing thresholds
  • Provides both thresholds and trace history
  • Provides tools for sound field calibration
  • Automated attenuator control and gain adjustment
  • Data export into MSExcel for post-process analysis and reporting

 

REATPro is the third generation of the REATMaster software originally developed in 2007 by Nelson Acoustics Software for the NASA Glenn Research Center and in conjunction with technical input from NIOSH. In 2010 the REATPlus second generation application of hearing protector evaluation was released which added additional features.  IN 2014 REATPro was released and has been adopted by several large hearing protector manufacturers and government hearing protector laboratories.  REATPro has been enhanced with additional features and is now supported by ViAcoustics for laboratories with an interest in hearing protector attenuation measurement.

REATPro Real Ear Attenuation at Threshold Software Features at a Glance:
3d database with tools
REATPro – Setup

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


Measuring instruments on graph paper,  conceptual vector set
REATPro – Manual / Calibration

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 – Documentation

Retrieve 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 – Test Execution

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.

REATPro – Excel Export

Export to MSExcel based template files that users can customize to meet their own needs. Both Unoccluded and Occluded thresholds, as well as the sound pressure level vs time trace history to MSExcel for detailed analysis of threshold determination time and reversal history. A file header section provides documentation on all test setup parameters.

REATPro – Comparison

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