The loudness, L, measured in decibels (Db), of a sound intensity, I, measured in watts per square meter, is defined as L = 10 log StartFraction I Over I 0 EndFraction, where I 0 = 10 Superscript negative 12 and is the least intense sound a human ear can hear. What is the approximate loudness of a rock concert with a sound intensity of 10–1?

A. 2 Db
B. 22 Db
C. 60 Db
D. 110 Db

The approximate loudness of a rock concert with a sound intensity of is 110 Db.

Step-by-step explanation:

The loudness, L, measured in decibels (Db), of a sound intensity, I, measured in watts per square meter, is :

We are supposed to find  What is the approximate loudness of a rock concert with a sound intensity of

So,

Substitute the values in the formula :

L=110 Db

So, the approximate loudness of a rock concert with a sound intensity of is 110 Db.
