# What sound intensity corresponds to 28 dB? a) 2.8 x 10^(-12) W/m^2 b) 1.8 x 10^(-10) W/m^2 c)...

## Question:

What sound intensity corresponds to {eq}28\ \rm dB {/eq}?

a) {eq}2.8 \times 10^{-12} \ \rm W/m^2 {/eq}

b) {eq}1.8 \times 10^{-10}\ \rm W/m^2 {/eq}

c) {eq}6.3 \times 10^{-10}\ \rm W/m^2 {/eq}

d) {eq}1.0 \times 10^{2.8}\ \rm W/m^2 {/eq}

## Sound Loudness Level:

The loudness of a sound is compared with the minimum audible sound intensity for human ear. Since the logarithmic scale is used to find the loudness level, the higher the intensity of sound, the higher the loudness level is.
