SOUND INTENSITY AS A FUNCTION OF SOUND INSULATION PARTITION

In the modem engineering practice, the sound insulation of the partiti ons is the synthesis of the theory and of the experience acquired in t he procedure of the field and of the laboratory measurement. The scien ce and research public treat the sound insulation in the context of th e emission and propagation of the acoustic energy in the media with th e different acoustics impedance. In this paper, starting from the esse nce of physical concept of the intensity as the energy vector, the aut hors get down to defining the sound insulation, influential parameter and real partition oscillations.
