Annoyance scale
Indicate numbers in the radar and in the Leq(M) readout on a scale related to cinema
SPL by selecting “Calibrated”, or on a scale relating to Digital level. Regulation in
most countries are based on “Calibrated” numbering.
Digital Reference Level
When the digital scale is selected, this parameter sets the value shown at 12 o’clock
position on the radar outer ring, and at the bold circle of the radar. This would
normally be set to the standard operating level. Note that this setting doesn’t affect
the Leq(M) readout below the radar, but it scales the outer ring and the radar itself.
The setting has no influence at all if Scale is set to Calibrated.
Calibrated Ref. Level
When the calibrated scale is selected, this parameter sets the value shown at 12
o’clock position on the radar outer ring, and at the bold circle of the radar. This
parameter can for instance be set to give a clear indication of the Leq(M) number that
shouldn’t be exceeded for too long. Note that this setting doesn’t affect the Leq(M)
readout below the radar, but it scales the outer ring and the radar itself. The setting
has no influence at all if Scale is set to Digital.
