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.

Ljud med en låg frekvens har en djupare ton, som till exempel hundskall eller ljudet av en gräsklippare. What is an audiogram? The frequencies (or pitches) that have been used during your hearing test are shown on the horizontal axis (the vertical lines). 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.

The shape of the audiogram resulting from pure-tone audiometry gives an indication of the type of hearing loss as well as possible causes. Conductive hearing loss due to disorders of the middle ear shows as a flat increase in thresholds across the frequency range. Sensorineural hearing loss will have a contoured shape depending on the cause.

The horizontal axis of the audiogram represents sound frequency or pitch measured in Hertz (Hz). 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. What to expect: This little demo is not too unlike the standard audiometric test known as a pure-tone audiogram.

PTA provides a method for separating conductive losses, located in the outer and middle ear, from sensorineural losses associated with problems in the cochlea and central nervous system.

1 The X-axis is divided into two parts: On the left side of the "divide" are the low frequencies. On the right side of the "divide" are the high frequencies. 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.

The frequencies (or pitches) that have been used during your hearing test are shown on the horizontal axis (the vertical lines). 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).

Ett hörseltest är en mätning av hur svaga ljud vi hör vid varje frekvens. Audiogrammet. Resultaten från ett hörseltest skrivs ut på ett diagram som kallas audiogram (

This is measured in decibel (dB). The lower on the axis, the louder the Air Conduction Testing – This is a pure-tone air conduction hearing test that determines the faintest tones a person can hear at specific frequencies. Earphones of the pure tone audiogram frequencies, tinnitus and periodic attacks of vertigo ( at least two in the past). Patients were excluded when other pathology was found 27 Oct 2020 and standard pure-tone audiometry by the same audiologist.
