As originally used, the bel representedthe power ratio of 10 to 1 between the strength or intensity i.e., power, of two sounds, and wasnamed after Alexander Graham Bell. Decibel definition, a unit used to express the intensity of a sound wave, equal to 20 times the common logarithm of the ratio of the pressure produced by the sound wave to a reference pressure, usually 0.0002 microbar.

A 70-dB dishwasher will sound about four times as loud as the 50-dB refrigerator, but in terms of acoustic intensity, the sound it makes is 100 times as powerful. Here's another way of looking at it: If the sound from one typewriter registers 60 dB, then ten typewriters Statistics for the Decibel (Loudness) Comparison Chart were taken from a study by Marshall Chasin, M.Sc., Aud(C), FAAA, Centre for Human Performance & Health, Ontario, Canada. There were some conflicting readings and, in many cases, authors did not specify at what distance the readings were taken or what the musician was actually playing. Food blender (88 dB); milling machine (85 dB); garbage disposal (80 dB). 80: 2 times as loud as 70 dB. Possible damage in 8 h exposure.
