Engineering Acoustics

Sound and vibration is of great concern for humans, society and industry. Our research and education aim to increase knowledge and understanding about sound and vibration phenomena for optimization, requirements and measures adapted to different needs and conditions.

The research is mainly conducted in projects linked to automotive industry, built environment and process industry. Education is conducted within Civil Engineering, Architecture, Industrial Design Enginering and Audio Engineering.

The research subject, founded 1989, has produced 20 doctoral dissertations. Today, the research team consists of 5 seniors and 2 doctoral students.

Fredrik Ljunggren, Professor in Engineering Acoustics

Fredrik Ljunggren's great interest in sound gained momentum when he, as a fifteen-year-old, bought his first stereo system. Today, his driving force is to create better sound environments in tall wooden house structures, both for the residents and for the sake of the environment.

Sweet music for microbes

In a new research project, researchers from Luleå University of Technology will investigate how microorganisms in biochemical processes reacts to different sound; audible sound and ultrasound. This is a unique experiment involving two research subjects at the university, Biochemical Process Engineering and Engineering Acoustics.

Innovative art and science

Art can evoke emotions and touch us – make us ask questions, create well-being, or provoke.Art can also help us to communicate experiences and information.When art meets technology, the creativity that exists within each area can together provide new opportunities to solve complex problems.
