Loudness

Loudness is measured in decibels (dB). Higher numbers are louder. Increasing the number of decibels by 3 is equivalent to doubling the sound level, ie. 63 dB is twice as loud as 60 dB.

Decibels	Example
100 dB	Motorcycle
90 dB	Lawn mower
75 dB	Vacuum cleaner
60 dB	Air conditioning unit
50 dB	Indoor fan
40 dB	Refrigerator
