An audiologist will use the describe the characteristics of the audiogram in the following ways: Type of hearing loss. Conductive – Normal hearing for bone conduction scores ([ & ]), and a hearing loss for Air Conduction scores (X & O). The pictures and letters in the chart above represent a normal hearing range at different volume and pitch levels. These range from very soft, like a whisper, to very loud, like a plane. When you look at an audiogram, you’ll see a graph with various lines and symbols. 2020-12-06 · Your audiogram should have shading to indicate the five different thresholds for hearing.

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). Thresholds measured between 0 and 20dB are considered to be within normal range.

Thresholds between -10 and +20 dB HL are considered in the normal range, while thresholds above 20 dB HL are considered diagnostic for mild, moderate, severe or profound hearing loss, as shown here: Particular causes of hearing loss will be show up in the clinical audiogram in characteristic ways.
