    • Sound absorption by suspended particulate matter 

      Brown, N. R.; Leighton, Timothy Grant; Richards, S. D.; Heathershaw, A. D. (NATO. SACLANTCEN, 1997)
      A series of experiments has been performed to study the viscous absorption of sound by particulate suspensions typical of those found in coastal waters. The effect due to the particles in the frequency range of 50 - 150 ...

    • The effect of suspended particulate matter on the performance of high frequency sonars in turbid coastal waters 

      Richards, S. D.; Heathershaw A. D.; Brown, N. R.; Leighton, Timothy Grant (NATO. SACLANTCEN, 1997)
      Shallow coastal environments are characterised by high levels of suspended mineral particles relative lo the open ocean and such suspensions can have a significant effect on the performance of high frequency sonars operating ...
