Display | Source Ranking

Opens the Acoustic Source Ranking bar chart window.  This window displays a bar chart ranking the relative strengths of the Acoustic Sources for all (or selected) M#s and all (or selected) shapes in a Shape Table

Acoustic Sources are defined in the Acoustic Source column of the M#s. spreadsheet.

Source Ranking

Measurements are associated with an acoustic source by giving them a common Acoustic Source name.  An acoustic source would typically be a physical source which is nearest to the Points associated with a group of measurements.

Source ranking sums the data from all of the Points associated with each Acoustic Source.  After each Source value is calculated, it is normalized by the total of the magnitudes of all of the Sources, yielding a percentage value for each Source.  Source ranked data can be,

  1. Displayed in a bar chart using this command.

  2. Animated on an acoustic surface by executing Animate | Animate Using | Acoustic Source in the Structure window

Naming Acoustic Sources

To give the same name to a group of measurements assigned to Points on an acoustic surface,

  1. Execute Tools | Create Animation Equations in the Shape Table window to create Animation equations in a connected Structure window containing the structure model and acoustic surface.

  2. Select a Substructure that defines a single Acoustic Source on the model in the Structure window.

  3. Execute Draw | Animation Equations | Select M#s to select the M#s in the Shape Table that are assigned to that Source.

  4. Double click on the Acoustic Source column in the M#s spreadsheet.

  5. Enter a name for the Acoustic Source, and click on OK.

  6. Repeat the above steps to name the other Sources on the acoustic surface
