The upper 2.5 Mm of the solar convection zone was simulated using a three-dimensional, compressible, hydrodynamic computer code. Results show that convection excites p-mode oscillations. The frequencies of the modes in the numerical simulation agree well with the eigenfrequencies of a computational box calculated for the time averaged mean atmosphere. The agreement is excellent at low frequencies, and diverges at higher frequencies in a manner similar to the difference between observed and theoretical frequencies for the Sun.
