To provide a sound wave receiving device, a device for determining sound source direction, and a method for determining sound source direction capable of accurately determining the direction of a sound source while suppressing the influence of sound wave noise generated by rotor blades of an aerial vehicle and external sounds which are reflections of the sound wave noise on surrounding structures.A sound wave receiving device 5 includes: an aerial vehicle 10 having rotor blades 12; an array sensor 21 mounted on the aerial vehicle 10 and including a plurality of microphones 21a; a first shielding member 40 installed between the rotor blades 12 and the array sensor 21, and suppressing an influence of sound wave noise generated by the rotor blades 12 on a sound wave received by the array sensor 21; and a second shielding member 50 provided along a peripheral portion of the array sensor 21, and suppressing reception by the array sensor 21 of external sound from outside a sound wave reception range set in advance for the sound wave.
