  The sense of line asymmetry of solar p-modes in the intensity power spectra
is observed to be opposite of that seen in the velocity power spectra.
Theoretical calculations provide a good understanding and fit to the observed
velocity power spectra whereas the reverse sense of asymmetry in the intensity
power spectrum has been poorly understood. We show that when turbulent eddies
arrive at the top of the convection zone they give rise to an observable
intensity fluctuation which is correlated with the oscillation they generate,
thereby affecting the shape of the line in the p-mode power spectra and
reversing the sense of asymmetry (this point was recognized by Nigam et al. and
Roxburgh & Vorontsov). The addition of the correlated noise displaces the
frequencies of peaks in the power spectrum. Depending on the amplitude of the
noise source the shift in the position of the peak can be substantially larger
than the frequency shift in the velocity power spectra. In neither case are the
peak frequencies precisely equal to the eigenfrequencies of p-modes. We suggest
two observations which can provide a test of the model discussed here.
