Part 3: Combining decibels and using log charts

WebThe decibel level of a sound having an intensity of 10 –12 W/m 2 is β = 0 dB, because log 10 1 = 0. That is, the threshold of human hearing is 0 decibels. Each factor of 10 in intensity corresponds to 10 dB. For example, a 90 dB sound compared with a 60 dB sound is 30 dB greater, or three factors of 10 (that is, 10 3 times) as intense. WebThe benefits of using dB are explained well in the Wikipedia decibel article: Level values in decibels can be added instead of multiplying the underlying power values, which means that the overall gain of a multi-component system, such as a series of amplifier stages, can be calculated by summing the gains in decibels of the individual ...
