Thresholds measured between 0 and 20dB are considered to be within normal range. As we examine the audiogram any sounds that fall below the persons thresholds (X’s and O’s) on the scale are audible, meaning you can hear them. If the sounds occur above the threshold measurement they would be inaudible.

Also, a person may have hearing difficulties despite having an audiogram that is within the range conventionally considered as 'normal'. One factor that may

Normal threshold for an adult: 0-25 dB Normal threshold for children: 0-15 dB AC and BC thresholds should be within 10 dB The pattern & position of the air and bone conduction results for each ear can be interpreted by the audiologist to explain the extent, nature and possible cause of any results that fall outside of the normal range. The vertical axis of the audiogram chart is used to show the loudness or intensity of the signal presented. An adult is classified as having normal hearing ability if their responses indicate they heard tones between 0 and 25 dB across the frequency range. A child is considered to have hearing ability within normal limits if their responses are between 0 to 15 dB across the frequency range. Keeping A Copy Of Your Audiogram Bone conduction thresholds should be between 0–25 dB in the range of frequencies 500 Hz and 4,000 Hz. Any air conduction thresholds are acceptable, because ADHEAR relies on bone conduction. Temporary or chronic conductive hearing loss. Unilateral or bilateral hearing loss.

Normal threshold for an adult: 0-25 dB Normal threshold for children: 0-15 dB AC and BC thresholds should be within 10 dB The pattern & position of the air and bone conduction results for each ear can be interpreted by the audiologist to explain the extent, nature and possible cause of any results that fall outside of the normal range.

Each threshold includes a range of intensity readings. The thresholds range from normal up to profound hearing loss. This allows you to see how well you can hear compared to someone in the normal range. Normal hearing ranges between 0 to 25 dB.

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

For humans, normal hearing is between −10 dB (HL) and 15 dB (HL), although 0 dB from 250 Hz to 8 kHz is deemed to be 'average' normal hearing. Humans can generally hear between 20 and 20,000 Hz. However, audiograms usually test frequencies between 250Hz and 8000Hz, mainly because human speech falls between 250Hz and 6000Hz. Mild hearing loss is indicated by the 20 – 40 dB range and is characterized by an inability to hear soft sounds.
