Introduction,ical basis of waves with mathematical expressions of wave signals that are necessary for the discrete signal analysis of sound and sound waves. A system constructed of a mass and a spring that is called a . is a good example to consider the fundamental issues of sound and vibration. Chapter 2 descri

Waves and Speed of Sound in the Air,e in which change in the local density of the air is propagated. Sound waves in the air can be characterized by sound pressure or particle velocity due to the dilation or condensation of a local area of the air. The direction of the particle velocity or displacement of a . is parallel to that in whi

Sound Waves in Rooms,een eigenfrequencies and eigenfunctions holds well for the wave equations as well as for linear equations. It might be quite rare to see a perfectly rectangular room in our daily life, but, room acoustics in rectangular rooms provide a good fundamental basis for better understanding of room acoustic

Room Transfer Function, of a source located in the room. The resonant peaks of the responses due to the eigenfrequencies are observed even if the source locations were averaged throughout the room. This explains why eigenfrequencies are so significant in room acoustics. The power response could be controlled by using seco
