The paper presents a simple mathematical model of wave propagation through bubbly water. Basing on the Zabolotska and Soluyan semiempirical theory of bubble oscillation nonlinear properties of a medium was estimated. The upper frequency limit of detection of nonlinearty parameter in free gas - bubble mixture was established.
