WebDecibel Formula. Decibel i.e. dB is the unit for expressing the ratio between two physical quantities, generally acoustic or electric power. Also used for measuring the relative loudness of the sounds. The decibel (dB) is a logarithmic unit used to measure the level of sound. Also, it is widely used in electronics, signals, and communication. WebThe decibel scale is logarithmic, which means that loudness is not directly proportional to sound intensity. Instead, the intensity of a sound grows very fast. This means that a sound at 20 dB is 10 times more intense than a sound at 10 dB. Also, the intensity of a sound at 100 dB is one billion times more powerful compared to a sound at 10 dB. http://physics.bu.edu/~redner/211-sp06/class-oscillations/notes24_intensity.html thomas hankins attorney
