MEASUREMENT DEVICE, MEASUREMENT METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/145440
Kind Code:
A1
Abstract:
This invention comprises: a propagation distance specification means for using a measurement result from a distance measurement sensor to specify a propagation distance that is the length of the propagation path that a sound wave transmitted by a transmission device travels through to reach a reception device; a propagation time specification means for specifying the propagation time until a sound wave transmitted by the transmission device reaches the reception device; and a measurement means for measuring an air characteristic at a position on the propagation path on the basis of the propagation time specified by the propagation time specification means and the propagation distance specified by the propagation distance specification means.
