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. Audiogram Symbols. 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.

Audiograms are created by plotting the thresholds at which a patient can hear various frequencies. Hearing loss can be divided into two categories: conductive or sensorineural. The results of an audiogram can help direct medical and surgical interventions to improve and/or preserve hearing function. 2012-05-07 2017-09-12 What is an audiogram?

Höger öra. Right ear.

Each ear is tested at octave intervals from 250-8,000 Hz and plotted on a pure-tone audiogram with the test frequency along the horizontal axis and the thresholds of hearing on the vertical axis. This is in decibels hearing level (dB HL), which ranges from minus 10 (at the top) to 120 (the loudest that most audiometers can generate). 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. Ställ en fråga vänd mot dator eller dylikt. Normal samtalston motsvarar en ljudnivå på ca 20dB.
