• The dynamics in the A and A_1 phases of superfluid ^3He is investigated. Second sound (entropy wave) and longitudinal spin wave are discussed within the framework of the hydrodynamic equations. In the A_1 phase, T_<A_1>>T>T_<A_2>, second sound is strongly coupled to a spin wave, while in the A phase far from the A_2 transition T_<A_2> they are separated. In the A phase close to T_<A_2>, where the order parameter has characters of the A and the A_1 phases, they are coupled, the coupling being determined by temperature, pressure and magnetic field. The detectability of the coupling effect depends on the frequency or the wave vector.
