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.

If you are having a normal conversation then you are producing 60-70 decibels, if you are in a loud rock concert, the sound reaches up to 125 decibel.
