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 21 doctoral dissertations. Today, the research team consists of five seniors and four doctoral students.

In the media: Follow into the quiet room - where sound drowns

Join us in an almost unique quiet room at Luleå University of Technology. Professor in Engineering Acoustics, Örjan Johansson, talks about how the sound of blinkers is captured on tape and how people usually react when all the sound around them suddenly disappears.

Ultrasound technology for a better juice

Using ultrasound technology, researchers at Luleå University of Technology aim for producing fruit juice without additives. The goal is to create a small scale industrial production process that retains the unique character of the fruit raw material and a juice with a natural aroma and taste.

In the media: That's why we sleep better with background noise

Arne Nykänen, assistant professor of technical acoustics at Luleå University of Technology, explains the white noise phenomenon.

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.
