SPL Over Distance Settings.

These settings define the frequency bands plotted by the SPL over Distance Panel.

Frequency Bands

The SPL over Distance Panel plots up to three traces per audience area - dotted, solid and dashed - each showing an SPL band of your choice. The ‘Dotted Line’, ‘Solid Line’ and ‘Dashed Line’ rows each provide:

  • A band-category dropdown to select the type of band, including ‘Broadband’ and ‘Start Stop’ for a free frequency range. The Dashed Line also offers ‘Off’.

  • A frequency dropdown to select the band centre (hidden for Broadband), or the start frequency in ‘Start Stop’ mode.

  • A second frequency dropdown for the stop frequency, shown only in ‘Start Stop’ mode.

  • A weighting dropdown, shown only for Broadband. The default is Z (unweighted).

By default, the dotted line shows 80-250 Hz, the solid line 1-10 kHz, and the dashed line is Off. Use the dashed line to add a third band - for example the Broadband, A-weighted level - without losing the other two.
