This paper deals with the development of a new method for determination of powder form materials in plastic bag by sound. It is useful to determine the kind of powder form materials in the opaque plastic bag without open or contact. This detector utilizes the variation of the amplitude of the frequency response within entire acoustic system. The incident impedance of powder form materials varies with the diameter of particles and so on. For contactless determination, small distance gap between face of detector and plastic bag is adopted. Characteristic acoustic impedance and complex wave number are measured by the transfer function method. These measured parameters of powder form materials are introduced into theoretical analysis. The trends of the experiments and theory show good coincidence.
