Measuring apparatus, and measuring method

A measuring method comprising:

• determining propagation paths through which acoustic waves propagate, wherein the acoustic waves are transmitted from one or more transmitters, pass through a predetermined region and are received by one or more receivers;
• controlling the transmitters such that the acoustic waves are transmitted and propagate through the determined propagation paths;
• identifying each of propagation times required for each of the acoustic waves transmitted in response to the controlling of the transmitters to propagate each of the propagation paths;
• and
• measuring an air characteristic of the predetermined region based on the identified propagation times and length of the propagation paths.

A non-transitory computer-readable storage medium storing a program that causes a computer to execute a measuring method, the measuring method comprising:

• determining propagation paths through which acoustic waves propagate, wherein the acoustic waves are transmitted from one or more transmitters, pass through a predetermined region and are received by one or more receivers;
• controlling the transmitters such that the acoustic waves are transmitted and propagate through the determined propagation paths;
• identifying propagation times required for the acoustic waves transmitted in response to the controlling of the transmitter to propagate the propagation paths;
• and
• measuring an air characteristic of the predetermined region based on the identified propagation times and length of the propagation paths.
