Power (Watts)/ Decibels (if the speaker is efficient)

2 Watts = 93 decibels

4 Watts = 96 decibels

8 Watts = 99 decibels

16 Watts = 102 decibels

32 Watts = 105 decibels

64 Watts = 108 decibels

128 Watts = 111 decibels

256 Watts = 114 decibels

512 Watts= 117 decibels

1024 Watts = 120 decibels

Some Volumes to Compare

10 decibels = normal human breathing

60 decibels = normal human conversation

110 decibels = power saw, car horn, shouting in ear,

120 decibels = jet aircraft close by, emergency vehicle siren, rock concert
