Vibroacoustics is a eld of science that deals with vibration and acoustic processes observed in nature, engineering, machines and equipment, means of transport, and communication, that is, in the entire work and life environment. It is useful in reducing vibroacoustic disturbances to the minimum level attainable with the current knowledge and technology.
