This paper presents a theoretical study of sound wave propagation through media whose properties change along one of the coordinate rectangular axis, properties that remain constant in the plane orthogonal to this axis. Fish schools, dense concentrations of plankton, or special composite materials could be modeled as such an inhomogeneous layer. The results were applied to obtain the transmission coefficient of an inhomogeneous layer of a given thickness, density velocity and attenuation gradient, sandwiched between the same homogeneous and semiinfinite media (water). The transmission of acoustic waves by an inhomogeneous layer, with doping of load particles which increase and after decrease the concentration in depth into the viscoelastic layer, is take into account. We assumed the following conditions: low particles concentration, low particle sizes as compared to the wave length, and normal incidence of the acoustic waves. It was concluded that the transmission coefficient of the layer varies with the frequency in a typical way and is dependent of the gradients of volume concentration, and the physical and geometrical properties of the particles.
