Decibles

What is the intensity of sound at the pain level of 120 decibels? Compare that to a whisper at 20 decibels
Question asked by: bubalex1

Asked on: 24 Feb 2011

It's not a linear relationship - decibels are actually logarithmic so there is not simply a 6 fold factor between 20 and 120.

The formula to calculate the difference between decibel levels is given here - hard to type!
