Answer 1

Answer:

Loudness is measured in decibels (dB). As decibels rise, loudness quickly increases. A 10-dB rise is a 10-time leap in loudness. That means an 80-dB sound (a vacuum cleaner) is 10 times louder than a 70-dB sound (a telephone ringing) and 100 times louder than a 60-dB sound (normal conversation).
