Cees Mulder Biography
Education
Born in 1967 in The Netherlands, Cees Mulder studied electronics at the Hogeshool Utrecht (University of applied Science) where he obtained a bachelor's degree in 1991. He then followed post-graduate courses on sound balance at the Royal Conservatory at The Hague (Netherlands), on acoustics (Antwerp, Belgium) and electromagnetic compatibility (Eindhoven, The Netherlands). In addition to his technical education, Cees supports theatres by mixing sound for music and speech performances. He also acts as a sound engineer for music recording studios.
Professional Experience
From 1994 to 2000, Cees Mulder worked as an acoustician for the Philips international projects division. With support from his mentor Stefan de Koning (one of the inventors of the Philips MCR system at the Philips Research Labs), he specialised in reverberation amplification systems, a method for creating variable acoustics using electro acoustic means. Furthermore, Cees Mulder worked as an electronic engineer at D&R elektronica (mixing consoles) and as an acoustician at Peutz consultants (1993-1994) and LBP consultants (2000 to 2006). Since 2006 he works as independent consultant and as such he is amongst others since 2009 responsible for the acoustics at Sala Palatului in Bucharest, Romania, for the biannual Enescu Festival. At the 2015 edition he was even appointed by Kristian Jarvi, the conductor of the opening orchestra, as assistant to him for balancing the orchestras sound.
