In a standard audiogram, the numbers across the top of the graph start at 250 Hertz ("Hz," or cycles per second) and proceed to 8k Hz (8000 cycles per second), with the following one octave intervals: 250 / 500 / 1k / 2k / 4k / 8k. Every octave -- every interval across the top -- forms a square with every 20 decibel (20 "dB") change going down.

1. Frequency. Frequency or pitch of sound is measured along the horizontal axis of the graph in Hertz (Hz), from 125Hz to 8,000Hz. The higher the measurement, the higher the pitch of the sound.

Ett normalt samtal har en frekvens mellan 500 Hz och 3 000 Hz. Resultaten i ett audiogram markeras med röda cirklar för höger öra och blå kryss för vänster öra vid ett hörseltest. Hörtröskeln för varje öra går att läsa av genom att förbinda dessa markeringar med linjer. An audiogram represents an individual’s hearing ability by frequency (pitch) and intensity (volume). The softest sounds that a person can hear at a particular frequency is called their hearing threshold.

The audiogram is a graph showing the results of the pure-tone hearing tests. If we were to compare “normal conversational loudness level” (typically 60 dB)
