A Tutorial on the Decibel
(The natural logarithm written as ln, uses a base value of e, which is 2.71828.) For example, if the number in question is 100, the base value of 10 would have to be raised to the power of 2 2to equal 100. i.e. 10 = 100. Thus, the common logarithm of 100 ... Here are the formulas:

Here, b is called the logarithmic “base”. So, if y = log b x, then the logarithm function gives the number y such that by = x. For example, log3 √ 27 = log3 ...
