Question:
What is the intensity of a sound with a measured intensity level of 35.9 dB? ({eq}I_0 = 10^{-12} W/m^2 {/eq})
Sound Intensity:
If a sound wave incidents on a surface, then the effect of the power of the sound wave in the unit area of the surface is called the sound intensity. This intensity of sound is measured with reference of some value of sound intensity.
