Question

what is the intensity of sound of 70 dB?​

Answer 1

Answer:

A 70-dB dishwasher will sound about four times as loud as the 50-dB refrigerator, but in terms of acoustic intensity, the sound it makes is 100 times as powerful.

Explanation:

The Intensity of sound level (I) is defined as the energy transferred by that wave per unit area per unit time. The Intensity of the sound wave is given as,

{eq}I=\frac{P}{A} {/eq}

where P is time rate of energy transfer and A is the area at which the wave is falling.
