Animal Risk Modelling and Assessments

Linking exposure modelling to species-specific vulnerability.

From Sound Levels to Biological Risk

INSPIRE transforms advanced acoustic modelling into clear, defensible biological risk assessments. Our integrated framework evaluates species vulnerability, exposure severity, spectral sensitivity, cumulative context, and uncertainty—so decisions are based on real ecological consequences, not just sound thresholds.

We assess population status, seasonal habitat use, hearing sensitivity, behavioral response potential, injury criteria, and construction sequencing to characterize risk in a transparent, repeatable way. By explicitly addressing cumulative effects and uncertainty, we strengthen regulatory defensibility, support proportionate mitigation, and reduce review delays.

How We Quantify Animal Risk

INSPIRE defines biological risk by integrating species vulnerability, realistic exposure modelling, and frequency-dependent sensitivity. We evaluate population status, seasonal habitat use, hearing capability, and existing stressors, then quantify exposure using both pressure and particle motion metrics, injury thresholds (peak and SEL), and construction timing. Our spectral analysis examines overlap with functional hearing groups and potential communication masking—distinguishing broadband and band-limited effects—so risk conclusions reflect how animals experience sound, not just whether a single threshold is exceeded.

Cumulative Effects & Confidence

We stress-test risk across construction schedules, installation methods, and cumulative regional activity—then explicitly document uncertainty so regulators understand not just the conclusion, but how confident they can be in it.

Defensible, science-based animal risk modelling.

Service Highlights

Vulnerability Assessment
Species-specific evaluation of population status, seasonal habitat use, hearing sensitivity, and existing environmental stressors to define true biological sensitivity.
Exposure & Injury Analysis
Quantification of acoustic exposure using pressure and particle motion metrics, peak and SEL injury criteria, noise producing activity-specific timing and activity rates.
Spectral & Masking Evaluation
Frequency-dependent analysis of spectral overlap with functional hearing groups and potential communication masking to distinguish behavioral consequence from simple threshold exceedance.
Cumulative & Scenario Testing
Comparison of seasonal windows, installation methods, activity rates, and overlapping projects to assess shifting risk under realistic construction scenarios.
Uncertainty & Confidence Documentation
Sensitivity testing of key parameters, identification of material data gaps, application of precautionary assumptions where needed, and explicit documentation of confidence levels to strengthen regulatory defensibility.
Mitigation & Monitoring Strategy Support
Development of science-based monitoring ranges, clearance zones, and mitigation measures aligned with quantified biological risk.
