The decibel unit was first used to measure the loss in telegraphic circuits, and was named by the engineers at Bell Laboratories, in honour of Alexander Graham Bell. A 1dB loss was the smallest noticeable decrease in loudness of the signal. There is no lowest decibel level. Since the dB is a ratio, arbitrarily small signals may still have attached numbers such as -40dB. Have a crack at decibel in a good encyclopedia. The decibel is not an SI unit, though it is given definition by the appropriate International Electrotechnical Commissions. Historically, in audiometry, 0dB was defined as the quietest sound that the average young man could hear. (who had not had deleterious noise exposure) These surveys were commonly taken by military recruitment centres, fairgrounds and so on. Obviously, one half of the cohort could hear quieter sounds and one half could not hear quite so well.
