The lowest frequency that produces an interference maximum at a microphone located 2.00 m from the midpoint of two speakers, which are 0.537 m apart and oscillating 180° out of phase, can be calculated using the principles of wave interference. The path difference must equal an integer multiple of the wavelength for constructive interference. Given the distance and configuration, the calculated frequency is approximately 318 Hz, derived from the speed of sound in air and the geometry of the setup.
PREREQUISITESAcoustics engineers, audio technicians, physics students, and anyone interested in sound wave behavior and microphone placement for optimal audio capture.
