Research

Per Sjösten participates in the research project Into Noise, conducted by Professor Catharina Dyrssen at Chalmers Architecture. This is a three year project funded by the Swedish Research Council.

The goal is to understand sonic rooms in new ways, experience more cultural sentences and nuances, develop advanced sound design, find out how sound can support the creation of more clear or more architectural room sequences and how to develop musical-architectural qualities in the urban room.

Per has also worked extensively with research (and consulting) in Active Noise Control. Active control means that unwanted low frequency sound is reduced by interference with added sound, created by speakers or shakers. These are usually controlled by a pretty advanced, adaptive control system implemented on a signal processor. Per has a PhD in Applied Acoustics, with the thesis Active Noise Control of Enclosed Sound Fields (Chalmers, Göteborg).
