WitrynaUnderstanding logarithmic scales is vitally important to anyone who works with data on a regular basis. The Richter Scale, which measures the strength of earthquakes, is a classic example of a logarithmic scale, as are decibels (a measurement of sound intensity), lumens (a measurement of light intensity), and pH (a measurement of … WitrynaThe decibel measures sound pressure or electrical pressure (voltage) levels. It is a logarithmic unit that describes a ratio of two intensities, such as two different sound pressures, two different voltages, and so on. A bel (named after Alexander Graham Bell) is a base-ten logarithm of the ratio between two signals.
