Graduation: Automation of Sound level predictions

We are a leading shipbuilder offering an exciting internship in Acoustic Analysis.

About the Role

As an intern in the Sound & Vibrations Research Team, you will develop a methodology to analyze time‑domain data from sea trials and build a prototype tool to identify and characterize acoustic sources.

Project Objective

Develop a method and build a tool that processes audio recordings from sea trials to automatically:

• Identify acoustic sources (diesel engine, electric motor, propeller, cavitation, turbulence, pump/HVAC, etc.)
• Determine source characteristics (rotational speed/RPM, number of blades/cylinders, etc.)
• Quantify the acoustic contribution per source (level, spectrum, and derived metrics)
• Perform source separation to isolate each detected source’s contribution

The final result will be a prototype that supports acoustic experts in analysis, troubleshooting, and design validation.

Key Accountabilities

• Create a model that classifies acoustic sources from time‑domain recordings of pressures, accelerations, etc.
• Define source‑specific outputs such as RPM, number of blades, and number of cylinders.
• Develop a prototype application in Python/MATLAB.
• Deliver documentation and evaluation based on real Damen sea‑trial data.

Skills & Experience

• University Master student in Naval Architecture, Maritime Technology, Mechanical Engineering, Applied Physics or related field.
• Affinity with acoustics, spectrograms, and harmonic analysis.
• Familiarity with signal processing and machine‑learning frameworks.
• Analytical mindset.
• Strong programming skills in MATLAB or Python.
• Mastery of English (spoken and written).

What we offer

• Academic level mentoring throughout the internship.
• Internship compensation and travel allowance in line with company policy.
• Project with direct relevance to multiple business functions and future digital products.
• Potential for internal rollout and possibly a publication or conference contribution.
