Studying the Perception of Non-Stationary Sound

Opening a signal in Pa is required.

If you want to compute indicators for specific chunks of a signal, add cursors to mark out the signal.

1. From the drop-down list, select Indicators for non stationary sounds to explore perception for non-stationary sound.

   

   The Indicators for non-stationary profile sounds are selected and the related indicators are displayed.

2. In Signals, select the boxes corresponding to the signal(s) for which you want to compute the indicators.
3. If some of the selected signals are marked out with cursors, in Signals, click the signal, then select:
   
   

   • the Start-End check box to calculate the indicators over the whole signal,

   • the check box corresponding to a chunk between two consecutive cursors to calculate the indicators over this specific part of the signal,

   • the Start-End check box and one or several check boxes corresponding to chunks to calculate the indicators over each selected signal and chunks.

   The signal(s) as well as chunks are selected.

4. Repeat the step 3 for each signal including cursors.

5. Click Compute.

The results for each selected signal and chunks are displayed in a table.

You can now save the results. If you selected the Level vs. time profile, you can also display the curves.
