Logarithmic Scale Definition (Illustrated Mathematics Dictionary)
WebJan 25, 2024 · Did you know: A logarithmic scale is used when there is a large range of quantities. It is based on orders of magnitude, rather than a standard linear scale, so each mark on the decibel scale is the previous mark multiplied by a value. On the decibel scale, the quietest audible sound (perceived near total silence) is 0 dB. WebExample 3 Reading a logarithmic scale. One representation that often arouses public interest is the probability of dying from different causes in a year for an ‘average person’. Figure 13 compares the risks associated with a number of differing possibilities. Reading these probabilities is a little challenging because of the logarithmic scale. duodenal switch cholecystectomy
