Evert is an acoustic scientist/engineer at Duran Audio's R&D department. Evert's academic background is in Applied Physics. During his PhD research (1993-1997) Evert developed a direct sound enhancement system based on Wave Field Synthesis (WFS). He was one of pioneers in this field. He is specialised in electro-acoustics and focusses on loudspeaker array technology, beamforming and digital signal processing.
After a three year intermezzo, during which he worked as an (electro) acoustic consultant dealing with a lot of speech intelligibility issues in difficult acoustic environments, he joined Duran Audio in the year 2000. At Duran Audio he developed a new directivity concept for loudspeaker arrays, that is known as ‘Digital Directivity Synthesis’ (DDS). Further, his research focussed on measurement (i.e., verification) of highly directional wave fields (using an adapted ‘Holographic near field measurement’ method), design of DDS-driven cardioid loudspeaker columns and the formulation of a hybrid PSM-BEM model to improve simulation and optimisation of LF cardioid arrays. More recently he has been working on the improvement of speech intelligibility in traffic tunnels.
Currently he is doing research on the modelling and high resolution measurements of transducers and investigating, prototyping and testing the next generation of line arrays.
In 2007 Evert received the Peter Barnett memorial award of the Institute of Acoustics in the UK for his scientific achievements.
Evert is also responsible for the DDA simulation software, which is an ongoing activity. Next to his research activities Evert often writes and presents scientific papers and provides courses and trainings to designers/users at a regular basis. He also provides acoustic support to the Harman sales organisation and many consultants all over the world.
