AI summary

A flight speaker 1 firstly outputs an inspection sound while flying on a first route R1 in a linear shape connecting a position of a sound collecting microphone M disposed inside a concert hall P1, and identifies an optimal volume position where a volume of a received sound collected by the sound collecting microphone M becomes an expected volume. The flight speaker 1 outputs an inspection sound while flying on a second route R2 in an arc shape with a distance between the identified optimal volume position and a position of the sound collecting microphone M as a diameter, and identifies an output position where a sound waveform of the received sound from the sound collecting microphone M becomes an expected sound waveform.
