__NOTOC__ __NOEDITSECTION__ Acoustics Acoustics/Print version Image:Acoustics logo 2.JPG Acoustics is the science that studies sound, in particular its production, transmission, and effects. Sound can often be considered as something pleasant; music is an example. In that case a main application is room acoustics, since the purpose of room acoustical design and optimisation is to make a room sound as good as possible. But some noises can also be unpleasant and make people feel uncomfortable. In fact, noise reduction is actually a main challenge, in particular in the industry of transportations, since people are becoming increasingly demanding. Furthermore, ultrasounds also have applications in detection, such as sonar systems or non-destructive material testing. The articles in this wikibook describe the fundamentals of acoustics and some of the major applications.
