What is a decibel (dB)? - RapidTables

WebThe fact that acoustic pressures are so small is another reason why decibels make sense, because it allows us to state the acoustic pressure relative to a reference pressure and not worry about the specific pressure unit. 2. Comparing Decibels; Rules of Thumb. When comparing decibel values, it is important to keep in mind how decibels combine. WebSound Intensity Level (dB) = 10 log (I/I ref) where I ref is the reference intensity. In other words, the decibel is 10 times the log of the ratio of two intensities, and 20 times the log of the ratio of two pressures. The units for both SPL and SIL are dB relative to the reference intensity (often abbreviated as dB re 1µPa or dB//1µPa). oriellys gilbert az
