Abstract:
The household food waste disposer is attracting attention as one of the leading disposal systems in Japan, and it is thought that disposers will be installed in many condominiums from now on. Sound and vibration which are generated by a disposer will come under fire as a new noise source. To popularize the disposer in Japan, reduction of the sound and vibration which are generated by disposers is an important matter. In this paper, as a standard method for measurement and evaluation of the vibration which is generated by disposers, the determination of the vibromotive force level of disposers is studied by the comparison method. As a result, it is clear that the vibromotive force level of a disposer is influenced by the kinds of food waste, but the frequency characteristic is relatively unaffected, a behavior similar to that found for sound power level.
