Answer 2

Normal conversation is about 60 dB

Explanation:

Loudness of the sound produced by a vibrating object depends on the amplitude of vibration.  Loudness is proportional to the square of the amplitude. Thus, if the amplitude is increased by three times, the loudness increases by nine times. A sound's loudness is measured in decibels (dB). Normal conversation is about 60 dB, a lawn mower is about 90 dB, and a loud rock concert is about 120 dB.
