摘要

An investigation of the effects of various ground surfaces on the character of a reflected N-wave was performed. The response of an FAA field test microphone was compared with that of a standard condenser microphone and the response capability of an FAA transient data recorder was determined. The effect of microphone height and wave incidence angle with respect to both a rigid reference surface and several ground surfaces was evaluated in a sonic boom simulator. The ground surfaces tested included asphalt, medium density grass, spaded soil, coarse aggregate, etc. Two different N-wave signatures were used in the tests. (Author)
