About Embedded AcousticsEmbedded Acoustics was founded by experts in speech, hearing and acoustics from TNO (the Netherlands organisation for applied scientific research). They benefit from being able to draw decades of experience in various Research & Development projects, as well as software engineering and product development. They are known for developing the Speech Transmission Index, and were among the first to develop Active Noise reduction systems for hearing protection.

Sander van Wijngaarden
Sander van Wijngaarden graduated from the Delft University of Technology in 1996, obtaining his Masters degree in applied physics. His specialization was Perceptual Acoustics; his Masters thesis dealt with binaural pitch perception phenomena. Sander then joined the Speech & Hearing group at TNO, where he worked on a broad range of R&D projects including hearing protection (active noise reduction, wireless communications earplugs) and speech intelligibility (STI, development of listening tests). 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, and is published in a series of 4 articles that appeared in the Journal of the Acoustical Society of America. After gaining experience as a project manager (IPMA C certified) 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 and scientific roots. Sander is managing director at Embedded Acoustics.

Herman started his professional career at TNO in 1965, after obtaining a BSc degree in electronics. He started work on evaluation of electro-acoustic systems, which was to remain an important element throughout his career. Largely out of frustration with the tedious work associated with evaluating speech intelligibility in the conventional ways, Herman co-invented the Speech Transmission Index (together with Tammo Houtgast) in the 1970s. Besides speech intelligibility, Herman worked on a considerable number of speech-related topics, including automatic speech recognition. In 1990, Herman obtained his PhD on his dissertation "On measuring and Predicting Speech Transmission Quality." Over the course of his career Herman received a number of awards, including the prestigious Scientific Achievement Award from NATO and the Peter Barnett Memorial award from the institute of Acoustics. Herman retired from TNO in 2002, and has since worked on select projects and has also been lecturing worldwide. Herman is Senior Consultant at Embedded Acoustics.

Diederik Bakker obtained his bachelor degree electronics at the Hague University, Rijswijk, in 2008. The focus of his study was microelectronics and robotics in particular. He started his career by working as hardware design engineer at his own company. Later he used his expertise to work as a consultant at Arcadis focussing on Dynamic Traffic Management systems. Combing entrepreneurship, electronics and consultancy, Diederik is Lead Hardware Engineer at Embedded Acoustics. Phone: +31 88 8770711Email: diederik@ Jeroen Somers
Jeroen Somers obtained his bachelor degree electronics at the Hague University, Delft, in 2012. The focus of his study was embedded systems and hardware prototyping. During his study he was working as repair man and calibrator for numerous microcontroller based designs at Alflex. Now Jeroen is Hardware Engineer at Embedded Acoustics.

Jan Verhave
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 included 3D audio, Speech Transmission Index and Active Noise Reduction. Jan was lead engineer and programmer 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. Jan is Director of R&D at Embedded Acoustics. Phone: +31 88 8770702Email: jan@ Michiel van Leeuwen In 2005, Michiel van Leeuwen obtained his masters degree in Physics at Utrecht University. Soon after that, he started working in the field of acoustics. First at M+P - consulting engineers in Vught, where he worked on road and railway traffic noise. His specialty was automatic analysis of large datasets and designing new measurement methods. Now, at Embedded Acoustics, he combines his experience in software development and acoustics. Michiel is Lead Software Engineer and acoustics consultant at Embedded Acoustics. Phone: +31 88 8770713Email: michiel@ Kostas Sotirakopoulos
Coming from Athens Greece, Kostas Sotirakopoulos holds an MSc in Engineering Acoustics from the Institute of Sound and Vibration Research (ISVR), University of Southampton (UK). Through his master’s, he specialized in architectural acoustics and signal processing. His MSc thesis research project focused on the design of measurement techniques for the assessment of underwater lining materials. His previous education background includes a BSc in Statistics/Mathematics (2008) and a Diploma in Sound and Audio Engineering (2010). Kostas joined Embedded Acoustics in 2012 as an Acoustic Consultant/Software Engineer. Phone: +31 88 8770714Email: kostas@ Pieter Postma
Having been an enthusiast about everything that has buttons and displays since childhood, Pieter Postma decided to study electrical engineering. He obtained a bachelor degree from The Hague University in embedded systems and hardware prototyping. During his studies, Pieter gained experience with various companies, such as Stork, Getinge, Skydec and Thales. He did his graduation project with Embedded Acoustics. In his spare time, Pieter enjoys photography, hiking and winter sports. Pieter is currently hardware engineer at Embedded Acoustics. Phone: +31 88 8770714Email: Pieter@
