Each threshold includes a range of intensity readings. The thresholds range from normal up to profound hearing loss. This allows you to see how well you can hear compared to someone in the normal range. The pictures and letters in the chart above represent a normal hearing range at different volume and pitch levels.

hearing tested should know how to read the audiogram, but that’s easier said than done. Hopefully, after reading this article you will have a greater understanding of the principles discussed and use your knowledge going forward— be it in reviewing hearing test results you already have or when discussing your results at your next hearing test.

The blue X line shows the left ear results from an air conduction test. The red O line shows the right ear results. Users with this type of hearing loss are primarily affected in terms of sound loudness rather than clarity, as their inner ear and nerves are normal. What an audiogram of conductive hearing loss looks like; In this circumstance, bone conduction result is normal white air conduction result showing there is a hearing loss. to what is referred to as Hearing Level, abbreviated as HL. The HL unit is based on research that ascertained the amount of dB SPL needed to derive the average threshold (i.e., softest level in which a sound can be heard) at each frequency for large groups of normal hearing individuals (usually college students), the “0 dB HL level.” It should be emphasized that this problem is not unique to the WHO hearing-impairment grading system, as many others yield similar classifications for age-related hearing loss (or other sloping audiometric configurations, such as occupational hearing loss). 4 The fundamental problem for age-related hearing loss, as shown in Figure 1, is that hearing is often well within the “normal” range at the lower two frequencies (500 and 1000 Hz) included in most pure-tone averages, as is the case The pitches shown on the audiogram are those most important for hearing and understanding conversation. Each sound we hear when someone speaks has a different pitch and loudness.

What would this look like on the audiogram? Results from a hearing test are displayed on an audiogram. An audiogram is a graph that shows the softest sounds a person can hear at different pitches or frequencies. The closer the marks are to the top of the graph, the softer the sounds that person can hear.

The "o" sound is low in pitch and louder. The audiogram illustrates your hearing ability by showing your hearing threshold at various frequencies. Hearing threshold is an indication of how soft a sound may get before it is inaudible. A hearing threshold of between 0 and 25 dB is considered normal. How to read an audiogram?

The closer the marks are to the top of the graph, the softer the sounds that person can hear. 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. Users with this type of hearing loss are primarily affected in terms of sound loudness rather than clarity, as their inner ear and nerves are normal. What an audiogram of conductive hearing loss looks like; In this circumstance, bone conduction result is normal white air conduction result showing there is a hearing loss. So what is considered normal hearing, and what would that look like on the audiogram?

For example, it is possible that the individ-ual’s thresholds in one ear are 15dB, 25dB, and 35dB HL at 500, 1000 Hz, Screening audiometry presents tones across the speech spectrum (500 to 4,000 Hz) at the upper limits of normal hearing (25 to 30 dB for adults, and 15 to 20 dB for children). 17 Results are An audiogram represents an individual’s hearing ability by frequency (pitch) and intensity (volume). The softest sounds that a person can hear at a particular frequency is called their hearing threshold. This is usually represented by markings on their graph; red represents the right ear and blue represents the left. The other way sound is measured is frequency, or pitch. It's measured in Hertz (Hz). When hearing ability is tested, a range of 250 Hz to 8000 Hz is measured because it encompasses the speech frequencies, the most important range for communication.
