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.
