Show affiliationsUltrasonic resonator cells for liquid attenuation and sound velocity measurements down to 70 kHz are described. The resonators are provided with easy-to-obtain concavely shaped shaving mirrors as acoustic reflectors and separated piezoelectric devices for the coupling of the cell to the electronic set-up. The advantages of this construction are shown. The mode spectrum of the resonators is discussed and measurement and evaluation procedures, also considering higher-order satellite peaks, are presented. Possible sources of experimental errors are specified and examples of measurements are given to illustrate the favourable performance of the cell design.
