As part of a program to measure in situ acoustic parameters of sediments, transducers capable of measuring shear-wave speed and attenuation in laboratory sediments have been designed and fabricated. Transducers consisting of an array of ceramic benders have been found to be the most useful in measuring shear-wave parameters of high-porosity laboratory sediments. Measurements of shear-wave speed and attenuation in kaolinite clay sediments have been made using the ceramic bender transducers. These clays exhibit calculated shear moduli as low as 1.7×105 dyn/cm2 with shear-wave speeds from 2 to 40 m/s and attenuations from less than 100 dB/m to more than 500 dB/m.
