Decibels are in essence a measure of volume. The volume or intensity of sound is measured in units called decibels (dB), generally on a scale from zero to 140 (any higher than 140 and you are in trouble immediately). The higher the number in decibels, the louder the noise. The louder the noise, the greater the risk of hearing loss.
While 20 to 20,000Hz forms the absolute borders of the human hearing range, our hearing is most sensitive in the 2000 - 5000 Hz frequency range.As far as loudness is concerned, humans can typically hear starting at 0 dB.itch is measured in Hertz (Hz) and loudness is measured in decibels (dB). For a person with normal hearing, when it comes to pitch the human hearing range starts low at about 20 Hz. Thatâs about the same as the lowest pedal on a pipe organ.
