The acoustics group studies the generation, propagation and reception of sound waves, as well as transducers and related signal processing, in a wide range of scenarios: sound for the communication between humans (speech and music); the influence of sound (noise) on humans and animals; and technical uses such as for remote sensing, designing materials and devices for noise abatement, biodiversity assessment and underwater communication networks.

The acoustics group offers a specialization in acoustics in the international 2-year master programme Electronic Systems Design as well as the 5-year ELSYS master program. Acoustics courses are also available to students from physics, building engineering, and other 5-year programs.

The fields of application include the energy, building, transport, environment, medicine, ICT sectors and art.

The acoustics group works closely with the SINTEF acoustics group through the Gemini centre "Acoustics Research Centre."

Projects

Some current projects in the acoustics group are:

Underwater Acoustic Communication between Nodes: part of CAMOS

The CAMOS (Coastal and Arctic Maritime Operations and Surveillance) IE faculty "lighthouse project" aims at developing a robust integrated network of satellite, terrestrial and underwater nodes. The main objective of the research in underwater acoustics is to address the underwater acoustic communication and networking problems.

Hybrid method for calculating the radiated sound from vibrating structures

In this project, which is financed by the Research Council of Norway (Fripro), hybrid methods will combine element-based methods for modeling vibrations with edge-diffraction based methods for representing the air load surrounding the vibrating body. The project runs 2015-2018 in collaboration with CCRMA at Stanford University.

Modeling of horn loudspeakers

A horn loudspeaker is a special type of acoustic duct which acts as a transformer between a loudspeaker element and the air. The modeling requires accurate methods over a wide frequency range, and this project develops such models, taking the acoustic environment of the loudspeaker into account.
