RT60 measurement screen, while the measurement is running and data is being acquired
Once the measurement is completed, the energy decay curves are plotted. Use the arrows to
cycle through the frequency bands (note that you can choose whether to measure in 1/1 or
1/3 octave bands through the “settings” screen).
RT60 decay curves plotted once the measurement is completed (interrupted noise method)
Inspect the decay curves to visually verify that the measurement is correct. An incorrect
measurement (which should be rejected) may become apparent in any of the following
ways:
•
The plotted data points do not reflect the expected linear decay of energy:
the level does not decrease linearly over time. If this happens, the triggering
process may have been disrupted.
•
The linear decay curve that is fitted (drawn line) does not match the dis-
played data points. E.g., the starting point of the decay curve may be off.
