Question

The standard measure used to compare sound intensities is the ______ .

Answer 1

Answer: Decibels

Explanation:

Decibel is the unit which used to measure intensity of sound. Sound intensity is the power carried by the sound waves per unit area perpendicular to it.

`I = (P)/(A)` measured in W/m²

In decibels:

`I (dB) = 10 log_(10)(I)/(I_o)`

With each unit rise of decibel, the sound intensity varies by a factor of 10.
