Abstract
Equations are suggested in the present paper for the amplitudes and instantaneous frequencies of sound waves generated by a moving source. The equations are derived by means of the Space-Time Ray (STR) method and by the two-scale expansion method (the method of horizontal rays and vertical modes).
