Intensity (or volume) is measured in decibels (dB). Zero (0) dB is the softest sound that can be heard. Normal conversation is around 40dB to 60dB, a whisper around 30dB. A rock concert can average between 110 and 120 dB. Pain from hearing is subjective. Levels below 125 dB may be painful to some individuals. The sound from a jet plane is approximately 140 dB.
I can't figure out how to interpret my audiogram. I keep finding different standards for 'normal limits.' Some say it is 0-20 db, others 0-15 db. Some say it is 0-15 db for children and 0-25 db for adults.And yet others make it seem as though 0 db is the average threshold at all frequencies for 'normal hearing' young adults.he results themselves, however, fall in a bell-shaped curve, in exactly the same way that other human dimensions do (think average height, weight, age for example). The lower limits of what is considered normal gets influenced by how the information is going to be used.
