From the dynamical equation of barotropic relaxing media beneath pressure perturbations, and using the reductive perturbative analysis, we investigate the soliton structure of a (1+1)-dimensional nonlinear partial differential evolution (NLPDE) equation (の)y( (の)η + u(の) y + (u2/2)(の) y)u + αuy + u = 0, describing high-frequency regime of perturbations. Thus, by means of Hirotas bilinearization method, three typical solutions depending strongly upon a characteristic dissipation parameter are unearthed.
