Source: WordNetNot everybody should be laughing at everything at the same time. That's not even natural. My thing is to feel natural, because I don't want to feel like I could just make people laugh at every single joke, every single time, with the same decibel level. Patrice O'Neal

A common source of confusion in using the decibel occurs when deciding about the use of 10 × log or 20 × log. Source: Internet
For example, the decibel is a unit quantifying signal power log-ratios and amplitude log-ratios (of which sound pressure is a common example). Source: Internet
In April 2003, the International Committee for Weights and Measures (CIPM) considered a recommendation for the inclusion of the decibel in the International System of Units (SI), but decided against the proposal. Source: Internet
Calculations In order to add or substract levels the values that are expressed in decibel first must be divided by 10 (or 20). Source: Internet
