Please feel free to contact me if you want to hear more about me, my services, as well as my technical contributions. I am always happy to help and ready to take a non-committal conversation about my work.


I offer my services regarding e.g. sound performance optimization. I spend a lot of time especially regarding the subjective part where I make sure that the specific product can play as loud as it should, can cover the given frequency ranges, and generally optimizes quality.


I can help creating the perfect acoustics for your situation and room division. I have many years of experience and knowledge regarding the effect and perception of sound by the propagation of sound waves in all types of spaces.
