5.5.1 Decay
This display shows the response to a noise interruption or impulse. It also superimposes the curves
used to evaluate RT values and the averaged successive responses.
Spectrum Type
Tab
This tab switches between 1/1 octave bands 1/3 octave bands results.
Time Decay
Graph
This graph displays the time decay curves for the selected frequency band or
global.
Frequency
Selection
These buttons are used to display the next or previous frequency band on the
time decay graph and in the results (Selected Results).
Curve Selection
These buttons are used to select the visible curves on the time decay graph. T10,
T20 and T30 are the straight lines used to determine the reverberation times.
EDT is the straight line used to determine the Early Decay Time. All shows all the
iterations in the averaging process (unavailable in Auto Schroeder mode).
Global /
Frequency
This button is used to switch between frequency bands and global.
