## What is 1 dB?

Decibel (dB), unit for expressing the ratio between two physical quantities, usually amounts of acoustic or electric power, or for measuring the relative loudness of sounds. … One decibel (0.1 bel) equals 10 times the common logarithm of the power ratio.

## How is dB loss calculated?

For instance, if signal A has a power of 20 mW and signal B has a power of 5 mW: 20/5 = 4. Take the log of the the ratio of the signals by pressing the log button on the scientific calculator. For instance: log 4 = 0.602. Multiply this answer by 10 to find the decibels.
