Services / Acoustic Data Analysis
Expert analysis and reporting
JASCO Applied Sciences works with clients to provide the appropriate results when they are needed:
Preliminary interpretations of results in the field
Fully analyzed and interpreted results in comprehensive reports
Synthesis of multi-year results into comprehensive soundscape descriptions
JASCO’s rigorous editorial review process ensures quality in our reports, and our senior scientific reviewers verify each report before delivery to ensure it is scientifically accurate and focused on our client's objectives.
“JASCO provides excellent, high-quality technical work and are a pleasure to work with. All the staff are very responsive and professional.”
Advanced automated processing and detection
Our comprehensive data analysis software suites are continually developed and improved to keep abreast of innovations in the field and our own internal research programs. We use high-performance computing clusters to efficiently and reliably process large volumes of acoustic data to provide:
Automated detection and identification of marine mammal calls
Ambient sound level calculations
Seismic survey event detection and quantification
Vessel sound detection and quantification
Pile-driving sound detection and quantification
Our specialized bio-acousticians review samples to confirm the automated marine mammal detections and identifications; they also interpret the vocalization data in the context of the given project and environment.
Specialized manual analysis
Our specialized bio-acousticians review audio samples and spectrograms to confirm the automated marine mammal detections and identifications and to interpret vocalizations in the context of the given project and environment. Analysts review the data to:
Identify presence or absence of vocalizations for marine mammal species of interest
Classify marine mammal calls by species and call type
Identify presence or absence of seismic survey activity
Characterize the time and frequency parameters of acoustic events
Our manual analysis protocols are customized to meet the needs of your project.
Real-time analysis: passive acoustic monitoring
JASCO analysts provide real-time passive acoustic monitoring (PAM) solutions in the field. The experienced PAM operators listen to the acoustic data and inspect the spectrograms of the measured sound levels in real time. They log all anthropogenic noise events and marine mammal calls and can immediately notify survey operators of marine mammal detections. The raw data and a brief detection report can be provided immediately.
