We examined the influence of liquid height on mechanical and chemical effects in 20 kHz sonication with a new Langevin-type transducer. Mechanical effects were evaluated from the degradation of polyethylene oxide in aqueous solution and chemical effects were measured with potassium iodide solution. Standing waves or reactive zones were observed using sonochemical luminescence and aluminum foil erosion. The observed wavelength was reduced by coupled vibration, compared with the wavelength calculated by dividing velocity by irradiation frequency. As liquid height increased, mechanical effects were suppressed. In the case of chemical effects, the stable sonochemical efficiency gained at a height of over 120 mm, and the sonochemical efficiency were also markedly higher than those of a conventional horn-type one.
