Abstract: | Mud is a complex mixture of water and solid particles and acoustics can help on its control. The mud layer, as an acoustic
channel, is characterized by its propagation constant relating the wave frequency, the sound velocity, and the energy absorption.
If the input acoustic pulse is known, it is feasible to easily characterize the mud layer as a low pass filter (absorption);
if it is also possible to insonify the mud with sound of both low and high frequencies, the sound speed of the mud mixture
can be evaluated, and the propagation constant is then known. |
