These frequencies are low on the left side of the audiogram (250Hz), then gradually climb to higher frequencies on the right side (8000 Hz or 8kHz). An audiogram is the graphical representation of the results of pure-tone air conduction tests. Vertical lines represent the testing frequencies, arranged from low-pitched on the left to high-pitched on the right. Horizontal lines represent the loudness, from very soft at the top to very loud at the bottom. Pure-tone audiometric measures were obtained from 3,470 subjects who also completed a hearing questionnaire.

Sound frequency increases gradually the further one moves to the right along the axis. This movement can be compared to playing on the left side of a piano and gradually moving to the right side where the tone becomes more and more high-pitched. 2020-08-06 Then, bone conduction hearing thresholds are measured for tonal stimuli at the range of frequencies from 0.25 to 4 kHz, with the use of a headband with oscillator.

An audiogram is a graph or chart that displays the results of your hearing test.Initially, it might look like a bunch of indecipherable lines and symbols. But once you learn how to read and interpret your audiogram, you will better understand your hearing loss. Deciphering Your Results 1. Work your way from left to right. The left side will show you the lower frequencies, which mean lower sounds. 2.

This whitepaper reports technical measurements showing Oticon Xceed A pure tone audiogram, such as that seen in Figure 1, can identify which type of deafness a patient has. This is a subjective test that relies on the patient’s responses to stimuli. The audiogram examines air conduction (AC) and bone conduction (BC). Often, a child that fails a pure tone audiogram test will be referred for more testing on a different day.

Exempel på normalt audiogram. Normal hörsel ligger mellan 0 och 20-25 dB HL (Hearing Level = "audiogramdecibel"). Man kan mäta absoluta trösklar, dvs. den svagaste ton man kan höra, eller som i detta fall screening (sållningsundersökning). S på audiogrammet har denna betydelse. Ett audiogram är en grafisk bild av hörförmågan hos en person.
