Decibels

An equation for the loudness of a sound in decibels is L = 10 log R, where R is the relative intensity of the sound.

Question 1

The loudness of the music at a concert is about 115 decibels. What is the relative intensity of this sound?

Question 2

A regular conversation is found to have a loudness of 62 decibels. What is the relative intensity of this sound?

Question 3

How many times greater is the intensity of the concert than the conversation?

Graphically

Question 4
