Device for measurement of intensity of sound on surface of noise source in which microphone is placed in the body at the end of cylindrical pipe in its inner cavity that has smooth surface and is separated from the body by insulation insert, and the other end of the tube is connected to surface of noise source through viscoelastic and tightening elements. At that the long axis of the tube is normal to surface of the source and inner diameter of the tube is equal to diameter of microphone. |
