Stretched string

A stretched string is a wire which is made up of any metal that must have a larger length compared to its thickness. The ends of the wire are fixed, and when they oscillate or are plucked, it produces two reflected transverse waves of the same frequency and same amplitude. The waves or pulses are traveling in alternate directions and superimpose with one another. This waveform is named standing or stationary waves.

Question

In the figure, two speakers separated by distance d, = 2.00 m are in phase. You are standing 4.60 m directly in front of one speaker. Each speaker has an output power of 1.10 W. Because the speakers are at different distances, there will be frequencies at which the sound from the
speakers interferes destructively. But because the speakers are at different distances, the sound intensities will not be the same, so the destructive interference will not be complete. We want to find the sound level when there is destructive interference. Use 343 m/s for the speed of sound
in air.
