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.
Intensity, or loudness, is measured in decibels (dB). A person with hearing within the normal range with respect to loudness of sound can hear sounds ranging from 0 to 140 dB. A whisper is around 30 dB. Conversations are usually 50 to 60 dB. Sounds that are louder than 90 dB can be uncomfortable to hear.
