![]() ![]() For those looking to gain a deeper understanding of how audio works, whether to make better-informed decisions or simply for the sake of curiosity, its useful to lay down some ground rules that govern how audio systems behave relating to loudness and the decibel. With every 10dB increase, there is a tenfold rise in sound intensity, leading to a perceived doubling of loudness. It operates on a logarithmic scale, comparing the sound’s pressure level to a reference level. Electrical power and acoustic intensity are power quantites. The Decibel (dB) Scale & Audio Rules 101. In regards to sound, a decibel (dB) is a unit of measurement used to gauge the intensity or loudness of sound. How much louder is 20 dB compared to 10 dB The difference between 10 dB and 20 dB is 10 dB. A decibel is a logarithmic value to the base 10. It is normally measured using the A scale, which approximates the human ear’s response to a wide range of frequencies. The beauty of decibels is that they allow us to understand and calculate the differences between power, root-power and perceived quantities in sound and audio. Decibel: Named after the inventor Alexander Graham Bell, a decibel (dBA) is the unit used to express the intensity of sound. See the table of commonly used reference values. A letter following dB, such as dBm, indicates a specific reference value. See the table for a list of easily remembered decibel values for common ratios. ![]() We convert that into the more popular decibel scale or dB scale. Zero decibels indicates a ratio of exactly one.

This -20 dB means we have 0.1x (1/10 x) the sound pressure level and 0.01x (1/100 x) the power. Sound pressure level, or SPL, is a measurement of sound pressure that uses Pascals (Pa) as its unit of measurement. ![]()
