Under ideal conditions, if both the receiver and the emitter are at rest with respect to the ground, the wind blowing from the receiver to the emitter does not affect the frequency of the sound as perceived by the receiver. The frequency received ($V_y$) would be the same as the frequency emitted ($V_E$), because the motion of the medium (air, in this case) does not change the frequency of the sound for stationary sources and observers.
