Question: can sparse sound reveal movement without flooding the habitat with hardware?

01 / 07

01 · Research question

The habitat is dark. The measurement gap is not.

18%

of night hours carry a confirmed visual observation in the illustrative field brief.

01Camera traps miss movement outside their narrow cone.

02Dense sensor grids disturb the same corridor they measure.

03The target is a movement map with honest uncertainty—not a perfect label.

QUESTION

02 / 07

02 · Method

Three steps turn sparse echoes into corridor probability.

Stage 1

Listen locally

Six palm-sized arrays record short, synchronized windows.

Stage 2

Align events

Arrival-time differences locate candidate paths across pairs.

Stage 3

Calibrate doubt

A habitat prior widens probability when canopy noise rises.

03 · Experiment

A small field grid tests what sparse really means.

+0.11

AUROC over the pairwise baseline at six nodes in the illustrative result set.

But: uncertainty expands sharply below six nodes; the evidence does not support a four-node deployment claim.

RESULT

05 / 07

05 · Limits

The result is a map of confidence, not a census.

Wind-driven leaf noise overlaps the target band and weakens localization.

Manual verification covers only selected time windows, not every event.

The corridor prior may not transfer to open grassland without recalibration.

What the paper can claim

Sparse arrays preserve useful corridor-level discrimination in this illustrative site.

What it cannot claim

Species counts, universal transfer, or disturbance-free measurement.

06 · Conclusion

Sparse acoustic evidence can reveal a corridor—when uncertainty remains visible.

Method
Align short local windows before applying a habitat prior.

Evidence
Six-node performance stays above the pairwise baseline in the demo.

Next test
Recalibrate across habitat types before any broader claim.
