Pitch, loudness and frequency selectivity in low-frequency

Normal hearing ranges from 0 to 20 dB in all frequencies. From here on, the assumption is that you have a sensorineural hearing loss (that you have nerve damage to the inner ear). Nerve damage, unless sudden, is permanent. For conductive hearing losses, see your otolaryngologist (your ENT physician). An audiogram is a graph that shows the softest sounds a person can hear at different frequencies. It plots the threshold of hearing relative to an average 'normal' … 2021-01-29 Audiograms plot the minimum volumes at which a person can detect tones played at each frequency. “X” is used for the left ear and “O” represents scores for the right ear.

The vertical axis of the audiogram chart is used to … In normal-hearing ears both curves are placed on the audiogram plot within the range of values that do not exceed 20 dB HL (Fig. 19.6 A).In conductive hearing loss, air conduction thresholds worsen, so the air conduction curve is shifted down, by up to 50 dB HL, while bone conduction thresholds remain unchanged (Fig. 19.6 B). The difference between air conduction curve and bone conduction How to read an Audiogram and How to Understand Your hearing test resultswhat do they mean? What is an Audiogram?

Reading Your Audiogram. When reading your audiogram, first look at where all the symbols fall. The closer all the symbols are to the top of the audiogram graph, the better your hearing is. Then look to see if the bone conduction is in the normal range (above 20dB).
