The intensity of sound made by a jet engine from 100 feet away is 100.5 watts per square meter. Find the decibel level given that [tex]I_0 = 10^{-12}[/tex] watts per square meter.

Answer :

The decibel level is 115.

From the question, we have

The decibel level is

[tex]D=10log \frac{I}{I_o}\\=10log \frac{10^{0.5} }{10^-12}\\\\=10log10^{11.5} \\=10*11.5=115\\[/tex]

Decibel:

Since some noises are dangerous, we can measure the sound that surrounds us in order to be protected and informed. In actuality, loud noise can harm our hearing. Decibel is the unit of measurement for sound intensity. Because the human ear is so sensitive, you can hear anything, including a tremendous thunderclap, when your fingertip lightly brushes across your skin. The sound of a thunderclap is roughly 1,000,000,000,000 times more powerful than the tiniest audible sound in terms of power. That really does make a difference!
