2020-09-02 · Most speech falls into the 250 to 6000 Hz range, with vowel sounds being around the lowest frequency and consonants around the highest frequencies. The vertical axis (y-axis) represents intensity (loudness) of sound in decibels (dB). The lowest levels are at the top of the graph on the audiogram. The top left of the chart is labeled as -10 dB The audiogram illustrates your hearing by representing your hearing threshold levels at different frequencies. The hearing threshold levels show the point at which a tone can be perceived. A hearing threshold level of between 0 and 25 dB is normal.

2021-04-02 · The TONE of sound is measured in cycles per second (cps) or Hertz: Low bass tones range around 50 to 60 Hz. Shrill, high-pitched tones range around 10,000 Hz or higher. The normal range of human hearing is about 20 to 20,000 Hz. Along the top of an audiogram, a range of sound frequencies is shown. As you move from left to right on the audiogram, the frequencies increase, which means the tones become higher pitched. On the left side of the audiogram, the loudness of a sound signal is depicted. As you move from top to bottom on the audiogram, the loudness increases. An audiologist will use the describe the characteristics of the audiogram in the following ways: Type of hearing loss.
