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.

In the media: Ultrasound + juice = delicious?

Örjan Johansson, professor in Engineering Acoustics at Luleå University of Technology, is currently working on tests where ultrasound is "pushed" towards fiber in juice - you want to get better taste and retain nutrients.

In the media: Real sound in virtual reality

Technology from the gaming world provides new opportunities to present realistic sound examples in community building projects.

New acoustic lab for testing winter tires

The sound from the contact between the tire and the roadway is perceived inside the car as a source of irritation and a disturbance for coversations. Tire noise is a major part of the car's overall sound image and entails costly control measures on the part of the community.

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.
