Acoustic Editor – Short Leq processing software

Please note that Acoustic Editor for Windows has been superseded by the NoiseTools program and the Noise-Hub software platform.

Please contact Cirrus Research plc if you would like more information about these current programs and the instruments that they support.

The NoiseTools software that is now provided, free of charge, with the optimus sound level meters, the doseBadge noise dosimeter as well as the CR:260A and CR:800C sound level meters, provides all of the functionality of the Acoustic Editor software in a single program.

The Cirrus noise monitors such as the CR:245 and CR:243 instruments are now supplied with the Noise-Hub platform which replaces Corvus and Acoustic Editor.

Below is a brief overview of the capabilities of the Acoustic Editor program.

Acoustic Editor for Windows is a post processing software program that can display and analyse Short Leq Noise Profile files.

These files were created by a range of Cirrus sound level meters, noise monitors and noise dosimeters and the data was downloaded via a program such as dBLink1, Deaf Defier or Corvus.

The Acoustic Editor program was supplied as a cost option for the CR:700, CR:800A, CR:800B and CR:800C sound level meters.

The Time History display provides a plot of the entire file, with the axis automatically formatted for the optimum resolution. Any section of the graph can be enhanced by selecting the region with the cursors. The program can identify noise sources that correspond to a set of criteria or templates. The Noise Sources Can Be Identified By:

  • A Selection Between the Cursors in the Main Display
  • Between A User Defined Time Window
  • A Template System Similar to That Provided by the CR:240 Series Noise Monitors

The program can calculate noise parameters for the sources, and can calculate the overall levels with and without the noise sources present. This information is presented in tabular form. The program can also calculate cumulative and amplitude distributions, which can include the identified noise sources. All of the graphs and tables can be printed directly using any connected printer, or copied into another program for inclusion in reports and presentations.

Acoustic Editor requires Leq data files that have been downloaded from a Cirrus Research plc Sound Level Meter using the software supplied with that instrument, or by another suitable program. Acoustic Editor for Windows itself does not provide download functions. Leq data files can contain large amounts of data and therefore sufficient hard-disk space must be available for the storage of these files. A demonstration version of the Acoustic Editor program can be downloaded here.

The data must be downloaded with the appropriate program for the instrument in use. When the noise sources have been identified, the colour of the main display can be changed to show the background noise and the sources. Many different sources can be identified and displayed.

  • Time History Graphs with Zooming and Panning
  • User Selectable Resolution
  • Identification of Noise Sources with Automatic And Manual Coding
  • Amplitude & Cumulative Distributions
  • Calculation of Occupational Noise Parameters
  • Periodic Leq and Ln Values
  • Calculate Loudest and Quietest Periods
  • Application of User Defined Statutory Periods to Provide Simple Checking Against Pre-set Noise Limits
  • Multiple Files Open with Export of Tables and Graphs for Easy Reporting

Please note that Acoustic Editor for Windows has been superseded by the NoiseTools program and the Noise-Hub software platform.
