Underwater Acoustics Scientist | The Hague

Contribute to measure sound, model sound and predict how it propagates through solids, water and air. do you envision? Become Underwater Acoustics Scientist TNO in The Hague.

About this position

We are looking for a devoted new colleague to further expand TNO’s Acoustics & Sonar (A&S) department. Acoustics & Sonar is the department where all of TNO’s acoustic expertise comes together. The group consists of approximately 85 people, including the people from the electro-mechanical workshop. The work atmosphere is casual and informal, we feel the drive to deliver world-class work but manage to maintain a casual and informal atmosphere. The A&S department covers a wide range of topics, from sonar applications and noise control to ultrasonic systems. We measure sound, model sound and predict how it propagates through solids, water and air. We use sound to our advantage for finding objects, such as submarines, sea mines, intruders, underwater infrastructure, sea life, etc. Sometimes sound can be a nuisance and have adverse effects if it is perceived as too loud. In these cases we know how to reduce the sound levels and to design measures to reduce the detectability of military naval platforms and decrease the adverse effects for platforms, humans and sea mammals. For industrial applications – primarily in the aviation, semiconductor, and medical industry - we are developing innovative ultrasonic sensors and instrumentation for integrity monitoring and composition analysis. As underwater acoustics scientist you will typically be active in multiple applied research and development (R&D) projects to develop solutions for our various customers. You will use your knowledge and experience to help meet our customer’s needs. Projects vary in size and nature, from researching the potential of a theoretical concept to building equipment that works in the field, and from small projects running several weeks to large international consortium projects running over the course of multiple years. Each project has its own team, and no two projects are the same, so expect lots of opportunities to further develop yourself.

What will be your role?

The A&S underwater acoustics domain is primarily focused on defense applications such as anti-submarine warfare, mine counter measures and torpedo defense. We contribute to the safety of the Netherlands armed forces, in particular the Royal Netherlands Navy.

The main underwater sensing and imaging technology is sonar. Sonar is a very complex technology which requires understanding of a broad range of topics such as

  • Acoustic signal generation and acoustic sources and arrays,
  • Modelling of the acoustic signal as it travels underwater and interacts e.g. with surface waves, bottom topography and different thermal layers,
  • Interaction between the acoustic signal and objects, and the resulting echoes,
  • And the interpretation of received echoes to detect, track and classify objects.

The use of artificial intelligence (AI) and unmanned systems are of increasing importance, and consequently underwater autonomous operation, collaboration between various autonomous platforms, and underwater communications are important research areas.

For our projects we require a broad range of (technical) skills such as defining research and experimental activities, modelling physical phenomena, developing custom simulation tooling, simulating complex use cases and scenarios, developing novel sonar and other systems, carrying out experimental measurements, developing software products, and reporting results. Team members frequently interact with our customers and are actively involved in field measurements. If you feel that you can help us make progress in these areas and are looking for a job that is meaningful to society, offers lots of variation, and will challenge you as a scientist, you’ve found your match!


"I am delighted that my work is contributing to the development of new technologies which can lead to further progress. It’s so exciting to be involved from the very first stage, which consists of a purely scientific idea, and to help this develop into an application that will benefit the society of tomorrow.”
