Så här tolkas audiogram - MED-EL
When you look at an audiogram, you’ll see a graph with various lines and symbols. Each one represents a measurement of hearing: Black represents a normal conventional audiogram for one ear in octave steps between 125 and 8,000 Hz. Red depicts a notch peaking at 2,800 Hz that is missed by octave-step testing. Blue represents thresholds above 8,000 Hz that may elevate steeply as a function of age or moderate noise exposure. Audiograms are set out with frequency in hertz on the horizontal axis, most commonly on a logarithmic scale, and a linear dBHL scale on the vertical axis. For humans, normal hearing is between −10 dB and 15 dB, although 0 dB from 250 Hz to 8 kHz is deemed to be 'average' normal hearing.
When you hit play on the file you hear the audio snippet, which is usually taken from a podcast episode. 2020-02-12 · A normal Type A result shows a line that begins at -200 on the x axis. It should peak at 0.9 on the y axis and dip back down at +200 on the x axis. The line looks like a single, tent-shaped peak with equal sides on the right quadrant of the chart.
2020-03-10 · What is normal hearing on an audiogram? Looking at the above audiogram, normal hearing ability is represented in the blue shaded area above the 25-dB line that crosses the graph from left to right. If your threshold symbols fall in the blue-shaded area, your hearing ability is considered within normal limits.

How do you interpret audiometry test results? Black represents a normal conventional audiogram for one ear in octave steps between 125 and 8,000 Hz. Red depicts a notch peaking at 2,800 Hz that is missed by octave-step testing. Blue represents thresholds above 8,000 Hz that may elevate steeply as a function of age or moderate noise exposure.
An "O" often is used to represent responses for the right ear and an "X" is used to represent responses for the left ear. A key on the audiogram, similar to one found on a map, identifies what the different symbols mean. The pitches shown on the audiogram are those most important for hearing and understanding conversation.
Find audiogram stock images in HD and millions of other royalty-free stock photos, illustrations and vectors in the Shutterstock collection. Thousands of new, high-quality pictures added every day. 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.
Ett audiogram är till stor hjälp för att skilja mellan olika typer av hörselnedsättningar som orsakas av t.ex.
