| Abstract |
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 attenuation using multiple alternative ultrasonic devices were conducted. Using the results of the conventional experiments as a benchmark the reliability of these experiments is considered acceptable. This manuscript was originally submitted to the ICUA 2022 conference. |
