At a concert, a speaker emits sound uniformly in all directions. To test the power of the speaker, the sound technician plays one note with constant power and measures the intensity level at different locations. Suppose the technician plays a note of 423HZ, and measures an intensity level of 96.8dB a a location that is 52m away from the speaker. If they assume that the sound was emitted by the speaker was uniform in every direction, what is the power of the sound emitted by the speaker (in SI units)?

Question
At a concert, a speaker emits sound uniformly in all directions. To test the
power of the speaker, the sound technician plays one note with constant
power and measures the intensity level at different locations. Suppose the
technician plays a note of 423HZ, and measures an intensity level of 96.8dB at
a location that is 52m away from the speaker. If they assume that the sound
was emitted by the speaker was uniform in every direction, what is the power
of the sound emitted by the speaker (in SI units)?
