Karl has since an early age been interested in physics, especially mechanics, and history. His first University courses included history which he pursued in between his military service as second in command at a troop transport ship. In 1998 he started to study Engineering Physics with sub-track Applied physics at Uppsala University and graduated in 2003. In November the same year he started his PhD studies at KTH/Marcus Wallenberg Laboratory. In 2009 he finished his PhD thesis named “Wind turbine noise and background sound- Masking, Propagation and Modeling” focusing on how our perception of wind turbine noise interact with natural sounds, creating numerical models for different natural sounds and also investigating sound propagation. After that he started working as a researcher in the laboratory mainly in a project focusing on sound propagation from turbines and another project investigating sound quality aspects of aircraft noise. He has also worked with sound quality aspects from wind turbine noise and the soundscape in rural areas. In 2010 he received an appointment as assistant professor at KTH and has since been a visiting researcher in Trondheim at NTNU in 2012. His teaching at KTH is mainly a course in signal and system analysis for future vehicle engineers and he also gives guest lectures in wind turbine noise and computational atmospheric acoustics.
