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. The scoring engine uses 2 benchmarks together — the OptimalRange form drives the primary score, while 1 guard(s) constrain the result.

Evidence & Context
Grassy Dry Forest... ACI Range: 135.7 – 139.4
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 mature, structurally complex Grassy Dry Forest in Southeastern Australia.
Represents the healthy range of acoustic variation within structurally intact dry forest types in Victoria.
