Two loudspeakers placed 6.0 m apart are driven in phase by an audio oscillator, whose frequency range is 2332 Hz to 3020 Hz. A point P is located 4.5 m from one loudspeaker and 3.6 m from the other. The speed of sound is 344 m/s. The frequency produced by the oscillator, for which destructive interference occurs at point P, in SI units, is closest to:

A Two loudspeakers placed 6.0 m apart are driven in phase by an audio oscillator whose frequency range is 344 Hz to 907 Hz. A point P is located 4.7 m from one loudspeaker and 3.6 m from the other. The speed of sound is 344 m/s. The frequency produced by the oscillator, for which constructive interference of sound occurs at point P, is closest to:
