Construction Monitoring
Marine construction activities can generate underwater noise that affects marine mammals, fish, and surrounding ecosystems. Monitoring these sounds helps project teams assess environmental impacts, evaluate mitigation measures, and support regulatory requirements throughout construction operations.
Ocean Sonics’ icListen smart digital hydrophones provide accurate acoustic measurements for monitoring underwater noise during activities such as pile driving, dredging, and offshore infrastructure development. Combined with Lucy II and the Impact Plugin, icListen supports real-time acoustic analysis, impact noise measurement, and reporting to help environmental professionals make informed decisions during marine construction projects.
Key Applications
Marine Construction Noise Monitoring
Impact Noise Measurement
Marine Life Impact Assessment
Environmental Compliance Monitoring
Why Choose the icListen?
- Accurate Measurements: Capture calibrated underwater acoustic data to assess noise generated by marine construction activities.
- Real-Time Monitoring: Stream and analyze underwater sound during active construction operations.
- Impact Noise Analysis: Detect individual acoustic impacts and measure relevant sound exposure metrics using the Lucy II Impact Plugin.
- High Dynamic Range: Measure a broad range of sound, including high-intensity construction noise within the hydrophone’s measurement limits.
- Flexible Deployment: Integrate hydrophones into portable systems, fixed monitoring stations, and marine construction monitoring setups.
- Reporting Capabilities: Generate measurements and reports to support environmental assessments and project-specific regulatory documentation.
Acoustic Monitoring During Marine Construction
See how Alaska Seismic and Environmental used Ocean Sonics hydrophones to measure underwater blasting noise during the Statter Harbor Improvement Project in Juneau, Alaska.
Acoustic recordings were used to assess underwater sound levels against marine mammal protection thresholds, demonstrating how hydrophone monitoring can support environmental compliance and mitigation planning during marine construction.
