Perturbation theory is used to calculate the frequency shift of acoust
ic modes of a homogeneous turbulent fluid and the frequency shifts of
solar modes due to turbulent convection. For sound waves in a random f
low, the fractional frequency shift is +(11/30)M-2 in the long-wavelen
gth limit, and the shift at Short wavelengths is -2/3M(2), where M is
the average Mach number of the flow. In our model of solar convection,
the low-degree f-mode shift is positive and unobservably small, where
as the fractional frequency shift at high degrees (l much greater than
500) is -M-2, where M is the Mach number of convection near the solar
surface.
