• Sound generates when the compressed air is blown onto an open-ended face of a small pipe. The sound frequency varies with the displacement of a solid placed close to the other open-ended face of the pipe. Taking this phenomenon into consideration, a new measuring method for small displacement is examined and developed. In this paper, the relationship between the sound frequency and the displacement is experimentally obtained, and the behavior of an air jet blown onto an open-ended face of the pipe is theoretically analyzed.
