Decibels are the measuring unit for sound energy. The absolute threshold for hearing is arbitrarily defined as zero decibels. Every 10 decibels correspond to a ten-fold increase in sound. Thus, normal conversation (60 dB) is 10,000 time louder than a 20 dB whisper.

I don't understand the math of the 10 fold system.

Could someone go into detail of it for me?

I just don't see how that works.

10 db = 100

20 = 1000

30 = 10000?

i don't understand the system here.
