Title:
SOUND WAVE RECEPTION DEVICE, SOUND SOURCE BEARING STANDARDIZATION DEVICE, AND METHOD FOR STANDARDIZING SOUND SOURCE BEARING
Document Type and Number:
WIPO Patent Application WO/2023/053847
Kind Code:
A1
Abstract:
Provided are a sound wave reception device, a sound source bearing standardization device, and a method for standardizing sound source bearings, with which it is possible to suppress the effect of sound wave noise produced by rotating blades of an aircraft, as well as the effect of external sound in which such sound wave noise is reflected by a surrounding structure, and to precisely standardize the bearing of a sound source. The present invention comprises: an aircraft 10 having rotating blades 12; an array sensor 21 that is mounted on the aircraft 10 and is composed of a plurality of microphones 21a; a first shielding member 40 installed between the rotating blades 12 and the array sensor 21, the first shielding member 40 suppressing the effect of sound wave noise produced by the rotating blades 12 on sound waves received by the array sensor 21; and a second shielding member 50 provided along the peripheral edge of the array sensor 21, the second shielding member 50 suppressing reception, by the array sensor 21, of external sound from outside of preset sound wave reception range for the sound waves.
