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.
Audible Range of Human Hearing â The average person has a normal hearing range that falls between 20Hz on the low side and approximately 20,000 Hz on the high side.As we age the overall perceivable range of sound decreases especially in the higher frequencies.requency is measured using the Hz symbol meaning Hertz. The chart above shows a total span of frequencies from 20 Hz to 130,000 Hz. Noting that the limitation of the range of human hearing is between 20 Hz and 20,000 Hz one can easily see that frequencies exist outside of our capability to hear them.
