The electrorheological (ER) liquids possess the ability to change their physical properties like the apparent viscosity and modulus of elasticity which is related to stiffness under influence of external electric field. They serve successfully in the field of semi-active/active vibration control - as well as in many other areas. The STL was investigated for various kinds of ER suspensions in the frequency range from 100 Hz to 2 kHz. An influence of the electric field density on the STL was different for normal and tangential sound wave propagation. In both cases the STL decreases with the increasing electric field density. Those properties can be potentially useful in sound propagation control applications.
