The presence of mineral particles in suspension results in excess acoustic attenuation which may be significant for high-frequency (tens to hundreds of kilohertz) sonar systems operating in shallow water. Laboratory measurements of absorption at 50-1

The visco-thermal absorption of sound by suspended particulate matter can be reliably measured using a reverberation technique. This absorption may have an adverse effect on the performance of sonars operating at 50–300 kHz in coastal waters where

Knowledge of the particle size distribution is required in order to predict ultrasonic absorption in polydisperse particulate suspensions. This paper shows that the method used to measure the particle size distribution can lead to important differenc

Current sonar performance models are incapable of accurately predicting the performance of high‐frequency sonars in highly variable turbid coastal waters. There is therefore a requirement for improved models incorporating the additional effects in

The visco‐thermal absorption of sound by suspended particulate matter can be reliably measured using a reverberation technique. This absorption may have an adverse effect on the performance of sonars operating at low ultrasonic frequencies in coast
