Question
A stereo speaker represented by $P$ in Figure $13-22$ emits sound waves with a power output of $100.0 \mathrm{W}$. What is the intensity of the sound waves at point $x$ when $r=10.0 \mathrm{m} ?$(See Sample Problem 13A.)

See Sample Problem A. A stereo speaker represented by $P$ in the figure on the right emits sound waves with a power output of $100.0 \mathrm{W}$. What is the intensity of the sound waves at point $x$ when $r=10.0 \mathrm{m} ?$
A sound speaker is rated at a voltage of $P=120.00 \mathrm{V}$ and a current of l=10.00 A Electrical power consumption is $P=I V$.To test the speaker, a signal of a sine wave is applied to the speaker. Assuming that the sound wave moves as a spherical wave and that all of the energy applied to the speaker is converted to sound energy, how far from the speaker is the intensity equal to $3.82 \mathrm{W} / \mathrm{m}^{2} ?$
The sound level 9.00 $\mathrm{m}$ from a loudspeaker, placed in the open, is 115 $\mathrm{dB}$ . What is the acoustic power output (W) of the speaker, assuming it radiates equally in all directions?
