Acoustic Complexity Index (ACI)
Benchmark Value
Scoring Curve
This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context.
Evidence & Context
Grassy Woodland... ACI Range: 130.5 – 137.0
Spectrogram complexity based on frequency bins (1–11 kHz), calculated as the sum of relative changes in acoustic intensity across temporal steps, using the mean of the 95th percentile daily values with 95% confidence intervals.
Healthy operational range for acoustic complexity in Grassy Woodland community in Southeastern Australia.
Grassy woodlands often represent the transition zones in subalpine foot-slopes and valleys, providing an excellent structural analogue.
