The origin of the word acoustics is the
Greek word akuein which means to hear. Thus acoustics concerns the
hearing mechanism and the perception of sound. Today the word covers a much
broader field of science. Acoustics has become the science of various aspects
of sound and vibration, like ultrasound in medical diagnosis, ultrasound for
seismic and sonar measurements, sound as unwanted noise and vibration, sound as
communication with speech and music, as well as aspects of hearing and
perception.
The scientific field of acoustics is related to a variety of
professions and commercial activities and administration, and is very often
connected to human activities. The main fields of interest of the Acoustics
Group are room acoustics, music and electro acoustics, measuring techniques,
numerical acoustics, material acoustics, hydro- and geoacoustics, and signal
processing. Additionally there is acoustics research and education in progress
in several other institutions in the Trondheim area.
