ISO3382 Acoustics Graphs
FuzzMeasure offers a set of fractional-octave graphs that calculate reverberation time and other values as laid out in the ISO3382 standard.
- Common Settings
- These graphs are all calculated using either Third-Octave or Octave Band decompositions of the Energy Decay Curve.
- Reverberation Time (RT60)
- The Reverberation Time graph estimates the time it takes for the direct signal to decay 60dB. It does this by calculating the slope of the decay over a specified range.
- Early Decay Time (EDT)
- The Early Decay Time graph is identical to the Reverberation Time graph except for the range over which it performs its estimate.
- Clarity
- Clarity is a measure of the ratio between the energy from 0 to Tms, and Tms to infinity, where T is a user-selectable interval value.
- Definition
- Definition (D50) is the ratio between the energy from 0 to 50ms, and the energy over the whole signal (from 0 to infinity.)
