If one signal is 10 dB louder than another, it has 10 times greater power. So it is a logarithmic scale. A 20 dB increase is 100 times, a 30 dB is a 1,000 times, etc. Note that say 10 dB has no dimensions (metres, grams, etc), it means 10 times, unlike Watts per square metre.

10 dBm would be 10 times that or 10 mW. -6 dBm would be ¼ mW. In 2020-09-02 · For every 10 decibels that are generated, it creates a noise level that is ten times louder. In other words, 74 decibels is ten times louder than 64 decibels which helps give you an idea of how decibels are measured. Plus, the decibels are measured from about 7 meters or 7 yards away from the unit itself. Even a small increase in decibels has a large impact on how intense a sound is, for example - 90dB(A) is 10 times more intense than 80dB(A), where 80dB(A) is the Lower Exposure Action Value in most Health and Safety legislation.
