What is the intensity of sound from a band with a sound level of 123 dB? (I₀ = 10−¹² W/m²)

Question

Quizplus · Accepted Answer

The intensity of sound is given by the formula:$$I = I_0 	imes 10^{dB/10}$$where:* I is the intensity of sound in W/m^2* I0 is the reference intensity of sound (10^-12 W/m^2)* dB is the sound level in decibelsSubstituting the given values into the formula, we get:$$I = 10^{-12} W/m^2 	imes 10^{123 dB/10}$$$$I = 2 W/m^2$$Therefore, the intensity of sound from the band is 2 W/m^2.
