Each line from top to bottom shows the loudness of the sound in decibels, with lines at the top of the chart for soft sounds (such as a ticking clock) and lines at the bottom for loud sounds (such as a lawnmower). For an adult, ‘normal’ hearing ranges from 0 – 20 decibels (dB) in all frequencies, and 0 – 15 dB for a child.

The average human can hear between 20 and 20,000 Hz Audiograms typically test frequencies between 250Hz and 8000Hz. Human speech usually falls between 250Hz and 6000Hz. AUDIOMETRIC TESTING: During testing, the audiometer delivers various “pure tone” sounds at particular frequencies and intensities, from low to high.

What does a normal audiogram look like? In fact, there are no normal audiograms as hearing ability differs from person to person. But in an audiogram that shows “normal hearing”, meaning no hearing loss, the ability to hear the different tones in the test should be under 25 dB at the different frequencies. A hearing threshold of between 0 and 25 dB is typically considered …

Severe hearing loss: 70 to 90 dB higher than normal. Profound loss: 90 dB or more. The graph to the left represents a blank audiogram illustrates the degrees of hearing loss listed above. Frequency is plotted at the top of the graph, ranging from low frequencies (250 Hz) on the left to high frequencies (8000 Hz) on the right.

average (PTA) at 500, 1000, and 2000 Hz is commonly used, although some entities utilize higher frequencies (3000 and/or 4000 Hz) in order to encompass the higher frequency speech areas. The PTA (500, 1000, and 2000 Hz) calculated for the above audiogram is approximately 53 dB HL in each ear, a hearing loss in the moderate range.
