SUMMARY
The discussion centers on calculating the distance from speaker B for experiencing destructive interference with two loudspeakers emitting sinusoidal waves at a frequency of 172 Hz. The speed of sound in air is given as 344 m/s, leading to a wavelength of 2 meters. Consequently, the closest distance to speaker B for achieving destructive interference is determined to be 1 meter. This conclusion is based on the principle that destructive interference occurs at half wavelengths.
