  Advances in hydrodynamical simulations have provided new insights into the
effects of convection on the frequencies of solar oscillations. As more
accurate observations become available, this may lead to an improved
understanding of the dynamics of convection and the interaction between
convection and pulsation (\cite{Rosenthal+99}). Recent high-resolution
observations from the SOI/MDI instrument on the SOHO spacecraft have provided
the so-far most-detailed observations of high-degree modes of solar
oscillations, which are particularly sensitive to the near-surface properties
of the Sun. Here we present preliminary results of a comparison between these
observations and frequencies computed for models based on realistic simulations
of near-surface convection. Such comparisons may be expected to help in
identifying the causes of the remaining differences between the observed
frequencies and those of solar models.
