• Abstract:
  This Letter Report serves to deliver the third external release version of the USDOT Volpe
  
  Center’s SuperFAR Spectral Aircraft Noise Processing Software (Version 6.0). Earlier versions of the software were delivered to FAA in February 2015 and March 2016 via Volpe Letter Reports V324-FA5JB4-LR10 and V320-FA5JBH-LR7 respectively.
  
  This version of the software represents substantial improvements in the underlying structure of the code, minor bug fixes, and minor improvements in functionality, including:
  
  • Provision for generating verbose output to the Python shell for diagnostic purposes;
  
  • Improved handling of input variables and filenames;
  
  • Ability to generate and handle both single-spectrum and spectral time-history versions
  
  of cumulative test-day atmospheric absorption coefficients;
  
  • Increased flexibility in determining the temperature used for calculation of test-day
  
  soundspeed, as well as the ability to select alternate methods for calculation of
  
  soundspeed itself;
  
  • Improved reporting of test-day and reference bandsharing, as well as presentation of
  
  PNLTM with and without bandsharing applied;
  
  • Replaced TC1k flag with variable TCLowBand to allow for Pseudotone elimination to
  
  start at user-specified band. (For situations where an applicant might select 800 Hz
  
  instead of 1kHz, for example.)
  
  This version also benefits from having been exercised by Volpe as the primary resource for
  
  validation of applicants’ noise certification software and methodologies since the previous version was released.
