STUDY OF THE PACKAGING OF A SMALL ENGINE -- 2. THEORETICAL INVESTIGATION OF THE SOUND INSULATION EFFECT OF PACKAGE

The problem of reducing the radiated noise by enclosing an engine in a suitably designed package is considered. The sound attenuation effect of the package is analyzed theoretically for an enclosed engine, theoretical equations are obtained for two cases where the dimension of package is very large compared with the wavelength of sound wave and where the dimension is very small compared with the wavelength. Moreover, theoretical analysis is performed regarding the sound transmission loss of various types of package walls and some interesting results are obtained.
