Compare Decibel Values
Calculator for the comparison of decibel magnitudes. Most common, decibel (dB) is used for the measurement of loudness, but also for other dimensions, like for voltage level in telecommunications engineering A difference of 20 decibels relates exactly to ten times the strength, whereas 6 decibels are almost the double. The ratio between each step is 1.12201845430196.
Please enter two values, the third will be calculated.
Examples: a normal conversation takes place at about 55 dB. That is about 18 times as loud as whispering at 30 dB. Sound with 0 dB can just be heard with good ears under ideal conditions. At 120 decibels, a million times the strength of the threshold of hearing, even for short time spans a hearing impairment is to be expected.
