Multiple Choice

An audiogram is a graphic representation of what?

An audiogram shows how sensitive hearing is across different pitches by mapping the softest sounds a person can hear at each frequency. The horizontal axis lists frequencies from low to high, and the vertical axis shows the sound level needed (in decibels hearing level). For every frequency, the plotted threshold indicates the minimum intensity at which the person detects sound—the lower the point, the better the hearing at that frequency. This visual graph captures the relationship between vibration frequency and the minimum sound intensity needed for hearing, which is exactly what an audiogram measures. It’s not about vestibular function, ear canal size, or a speech recognition threshold.
