Sound and Vibration Control
Sound and vibration control, with HVAC and lighting, are parts of the environmental control systems of a building. Vibrations are undesirable. Some sounds also are objectionable, because they interfere with communication or the enjoyment of quiet or of music, or because they are meaningless or distracting. Such unwanted sounds are called noise. In contrast, certain sounds are necessary for communication or are desirable, because, as in the case of music, they produce pleasing sensations. Sounds useful for communication or for music are called signals.
