摘要：
The theory of periodical shear flow is applied for the exploration of the effect of solar granulation on high-frequency waves in the solar photosphere. It is shown that upgoing and downgoing waves are trapped in intergranular spaces and granules, respectively. Upgoing waves in fast downflows are unstable. The theory is in a good agreement with observations.
