Acoustic attenuation of cohesive sediments (mud) at high ultrasound frequencies Waterbouwkundig Laboratorium
The acoustic attenuation of cohesive sediment (mud) at high frequencies ranging from 0.5 MHz to 5.0 MHz is determined. Conventional laboratory experiments based on the pulse-echo technique were performed using a single element immersible ultrasound transducer. The results showed however that due to the time-changing properties of mud a different approach to process the data is required. Additional experiments to determine the acoustic ...
