Nocturnal Soundscape Acoustic Indices for Two Australian Reserves

Summer season summary of nocturnal sonotype richness and corresponding acoustic indices for Grandchester and Hidden Vale reserves. The dataset includes acoustic activity (ACT), acoustic evenness (AEI), spectral entropy (Hf), and soundscape saturation (Sm) metrics. It was authored by Felipe do Carmo Jorge and last updated on May 15, 2026.

Use Cases

• Compare acoustic activity (ACT) between two nature reserves.
• Analyze acoustic evenness (AEI) to assess soundscape balance.
• Evaluate spectral entropy (Hf) as a measure of acoustic complexity.
• Monitor soundscape saturation (Sm) across different animal groups.
• Study nocturnal biophony by comparing insect, bird, frog, and mammal sonotypes.

Strengths

• Data is explicitly focused on nocturnal soundscapes, a specific ecological niche.
• Includes four distinct acoustic indices (ACT, AEI, Hf, Sm) for analysis.
• Separates data for filtered (0.3-20kHz) and raw (0-20kHz) audio files.
• Covers two distinct geographic locations: Grandchester and Hidden Vale reserves.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (5.5 KB), indicating limited scope.
