This loudness is measured in a scale called decibels (dB). Any points that are heard at 20dB or quieter are considered to be within the normal range.The lower down the graph the points are plotted, the worse the hearing. The different shaded areas indicate the different classifications of hearing loss.he audiogram below shows the sounds have to be made louder before they are heard in the high frequencies (the right side of the audiogram), leading to a slope on the audiogram as seen below. This audiogram shows normal hearing up to 1KHz (mid frequency) and a mild hearing loss in the mid to high frequencies.
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.
