| Abstract: | The sound-pressure equations in stationary wave sound field were inferred theoretically and analyzed the nature of stationary wave.The sound velocity in the atmosphere in Lhasa was measured by standing wave experimentally in Lhasa and analyzed the impact of altitude on sound velocity.Finally,it experimental value and theoretical value was compared to obtain sound velocity value of the atmosphere in Lhasa. |
