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.
To put it simply, this means that an increase of 10 decibels means the sound is ten times louder. So a noise measurement of 80 dB is ten times louder than a sound measured at 70 dB! As a frame of reference, here are the decibel levels of sounds you may encounter in your everyday life.0-30 dB, Very Faint.Most human adults cannot hear sounds below 0 decibels.Most sound in this range is almost inaudible.o a noise measurement of 80 dB is ten times louder than a sound measured at 70 dB!
