Sander van Wijngaarden

Managing Director

Acoustical consultant

Sander van Wijngaarden obtained his Masters degree in applied physics from the Delft University of Technology in 1996. His specialization was Perceptual Acoustics. Sander then joined the Speech & Hearing group at TNO, where he worked on a broad range of R&D projects, mostly on hearing protection and speech intelligibility. He obtained his PhD from the Free University of Amsterdam in 2002. His PhD thesis ("The intelligibility of non-native speech") is based on work done at TNO.

After gaining experience as a project manager for several years, Sander was appointed team leader of the Speech & Hearing group in 2002. He took on a new challenge in 2006, when he joined a different division of TNO as a Business Developer. In 2007 Sander was appointed Department Manager in the Chemical and Biological protection department. Sander finally decided to leave TNO to co-found Embedded Acoustics in 2010, returning to his technological roots.

Jan Verhave

Director of R&D

Acoustical consultant

After obtaining his degree in electronics engineering in 1989, Jan joined the Phonetics department of the University of Amsterdam to work on a European "Esprit" project on speech technology. In 1993, he accepted a research associate position at TNO in Soesterberg. At TNO Jan specialized in real-time low-latency hard- and software for acoustic signal processing. Applications that Jan worked on include 3D audio, the Speech Transmission Index and Active Noise Reduction.

Jan was lead engineer and software developer in many development projects, including the first IEC-compliant STI measuring software application and several generations of Active Noise Reduction headsets (analog and digital). Jan was also the primary developer of STIPA and was involved in several commercial implementations of STIPA. He has been the driving fore behind most STI-related innovations over the last decade.

Pim Wubben

Project manager SentraTag

Pim obtained his Masters degree in systems and control engineering from the Delft University of Technology. Technology has always been one of his major interests, which led him to joining a solar car team during his studies as the mechanical engineer of the team. After one year of fulltime commitment on the solar car, his team ended up winning the world championships in solar racing. In the past few years, various positions at startups taught him the process of connecting the technological and commercial dots. He really enjoys bridging these two often somewhat separate territories, with the aim of creating cool innovation with true added value.

Miguel Asselbergs

Lead hardware engineer

Miguel has always been interested in technology, especially electronic devices. Since young he has been tinkering with electronics, therefore he chose to study electrical engineering. After obtaining his degree in electronics engineering from The Hague University, specializing in Embedded  Systems, Miguel joined Embedded Acoustics in 2016. Miguel combines high-level system engineering with electronics design and embedded software development.

Diede Dijkstra

Lead software engineer

As a little boy, Diede already picked up the habit of disassembling every old device he could find, out of interest in how these devices were built. So the choice to start studying Electronics was a very natural one. In 2017 Diede obtained his bachelor's degree in electrical engineering from the Rotterdam University of Applied Sciences. During his time as a student, Diede discovered he enjoyed coding more than anything else. Already having spent lots of hobby time creating programs, Diede decided to bring coding to a new level by making it his profession. He has since worked on a wide variety of projects. His track record includes various embedded platforms as well as mobile and desktop applications.

Luc van Leeuwen

Software engineer

Luc obtained his bachelor's degree in electrical engineering from the Rotterdam University of Applied Sciences in 2015. He did his thesis work at Embedded Acoustics, on a design for advanced fire fighter headset. After graduation, Luc developed his expertise and know-how in various fields, working as an embedded software engineer and a software consultant on a variety of applications. He joined Embedded Acoustics as a member of our (embedded) software team in 2020. Besides developing embedded software for a variety of products and hardware platforms, Luc has also been taken responsibility to initiate a process of ongoing improvement of our development process.

Stefan Oud

Embedded systems specialist

In 2015 Stefan Oud had finished his master degree in experimential physics at the University of Leiden. In his spare time he was interested in programming and he learned his skills autodidactically. He has also taught himself some basic knowledge of electronics. These practical skills combined with physics and system thinking, come to use in his work for Embedded acoustics. Stefan is the primary software developer for the Bedrock product line and contributes to various key projects at Embedded acoustics.

Ruben IJlst

Hardware engineer

Ever since Ruben was a young child, Ruben has been experimenting with electronics with the help of his grandfather. As just graduated mechatronics mechanic, he wanted to explore the electronics field even further, so in 2013 started studying electrical engineering at The Hague University in Delft, which he finished in 2017. During his study he worked on different group projects as software and hardware engineer and he worked as tutor at different electrical engineering courses at The Hague University. Ruben's work primarily revolves around the development of deeply integrated high end electronics, including miniaturized systems with embedded radio technology (such as LoRa and BT).
