This is measured in decibel (hearing level ) dBHL. The axis starts at -10dBHL (very quiet) and increases in 5dBHL steps upto 120dBHL (very loud). The frequency (tone/pitch) is read along the horizontal axis. 2006-08-01 2017-09-12 The average human can hear between 20 and 20,000 Hz Audiograms typically test frequencies between 250Hz and 8000Hz. Human speech usually falls between 250Hz and 6000Hz.

It also shows how severe it is, called the degree of hearing loss. For example, your hearing might be normal for low pitches but not for high pitches. In this case, you might hear speech, but it would not sound clear. 2017-09-12 · Normal Hearing: Pure-tone audiometry When air conduction (AC) and bone conduction (BC) thresholds are within normal limits.

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. 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.

An audiogram is a chart that shows the results of these tests and how well you or your child hears sound. It shows the softest sounds heard at different pitches and frequencies. The audiogram helps to diagnose the degree and type of hearing loss, as well as help identify possible treatments. An overview of an audiogram The vertical axis of the audiogram chart is used to show the loudness or intensity of the signal presented.
Simple. Start at the top left corner of the graph, at the lowest frequency (125 Hz). Your hearing
The results of a hearing test are written on a chart called an audiogram (a Normal range or no loss: 0 to 20 dB; Mild loss: 21 to 40 dB; Moderate loss: 41 to 65
The principal audiological investigation is pure tone audiometry combined with a This results in swelling of the endolymphatic sac and other tissues in the As opposed to typical spells in which tinnitus and hearing loss precede an
All results will be recorded on an audiogram. Important Note: those who “fail” will have normal hearing when tested and 5% who “pass” will actually have a
How to read hearing test results · Mild hearing loss is measured in the range of 26-45 dB. · Moderate hearing loss is in the 45-65 dB range; a person with this range

Hearing Loss and the Audiogram. An audiogram is a graph of behavioral responses to tonal sounds. The marks on the graph signify the softest level at which a tone is responded to by a patient, at each of a set of conventionally measured frequencies across the speech spectrum of sound.
