An audiogram is a graph that shows the softest sounds that someone can hear at specific frequencies. High-pitched sounds, for example a bird singing or a child squealing, have a high frequency. Sounds at low frequencies have a lower pitch, such as a dog barking or the noise of a lawnmower.

The axis starts at -10dBHL (very quiet) and increases in 5dBHL steps upto 120dBHL (very loud). The frequency (tone/pitch) is read along the horizontal axis. 2015-04-19 · The audiogram is essentially just a graph that records sound volume on the vertical axis and sound frequency on the horizontal axis. (are you having flashbacks to high school geometry class yet?) Yes, there’s more to it, but at a fundamental level it’s just a chart graphing two variables, as follows: What is an Audiogram?

Understanding the information shown on an audiogram is easy. Let’s look at an example. In the audiogram below, hearing thresholds for the right ear are represented by red circles and thresholds for the left ear are represented by the blue X. In the right ear, this person has normal hearing in the lower pitches indicated by a red circle corresponding to 15 dB at 250 Hz and 20 dB at 500 Hz. An audiogram is a graph that shows the audible threshold for standardized frequencies as measured by an audiometer. The Y axis represents intensity measured in decibels and the X axis represents frequency measured in hertz. The threshold of hearing is plotted relative to a standardised curve that represents 'normal' hearing, in dB.
Let’s look at an example. In the audiogram below, hearing thresholds for the right ear are represented by red circles and thresholds for the left ear are represented by the blue X. In the right ear, this person has normal hearing in the lower pitches indicated by a red circle corresponding to …
The "hearing ability" is expressed in dB HL (decibel hearing level), which measures "hearing loss." 0dB HL represents the average hearing threshold for people with normal hearing. The audiogram gives a “picture” of your hearing.
The audiogram is a graph that shows the softest sounds a person can listen to different pitches or frequencies. It is a hearing test that helps the doctor to detect hearing loss. Two types of hearing loss occur. Asymmetrical hearing loss and symmetric hearing loss.
The closer the marks are to the top of the graph, the softer the sounds that person can hear. What Normal Hearing Looks Like. So what is considered normal hearing, and what would that look like on the audiogram? Individuals with regular hearing should be able to perceive every sound frequency level (125 to 8000 Hz) at 0-25 decibels.

Vertical lines represent the testing frequencies, arranged from low-pitched on the left to high-pitched on the right. Audiogram – tolkning av audiometri Ett audiogram är till stor hjälp för att skilja mellan olika typer av hörselnedsättningar som orsakas av t.ex. ledningshinder eller presbyacusis. Se exemplen på hur olika audiogram ser ut i bilderna nedan. En normalhörande person kan uppfatta ljud med frekvensen 1 000 Hz vid 0 dB.

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. 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. What Normal Hearing Looks Like.
