These :ref:`settings<settings>` define the two frequency bands plotted by the SPL over Distance Panel.

**Frequency Bands**
    The SPL over Distance Panel plots two traces per audience area - one dotted, one solid - each showing an SPL band of your choice. The 'Dotted Line' and 'Solid Line' rows each provide:

    * A band-category dropdown to select the type of band, including 'Start Stop' for a free frequency range.
    * 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.

    By default, the dotted line shows 80-250 Hz and the solid line 1-10 kHz.
