Audiogram hearing test explained

The horizontal axis represents pitch, while the vertical axis represents the sound level needed for you to respond. Symbols distinguish the right and left ears and may record responses through headphones and through a small vibrator placed behind the ear. The chart describes a hearing pattern; it is not, on its own, a complete diagnosis of the cause.

Marks nearer the top of the chart represent softer sounds heard, and marks farther down indicate that louder sound was needed. Clinicians examine the shape of the plotted responses, differences between ears, and any gap between air- and bone-conduction results. These features may point toward an outer- or middle-ear barrier, an inner-ear pattern, or a mixture of both.

Speech understanding can differ from tone detection, so speech results may be reviewed alongside the chart. Your daily listening difficulties, ear examination, and medical history provide context that graph symbols cannot capture.

Bring previous audiograms if you have them, because comparison may reveal a change over time. Mention recent loud-noise exposure, blocked ears, infection, tinnitus, dizziness, and medicines that might affect hearing. Keep your response consistent during the test: signal whenever you think you hear the tone, even if it is barely audible.

Afterward, ask the clinician to explain the pattern in ordinary language and relate it to conversations, television, telephone use, or workplace sound. Depending on the findings, the next step could be an ear examination, treatment of blockage, further diagnostic testing, monitoring, or discussion of hearing support.

A sudden reduction in hearing needs urgent medical assessment, particularly when it affects one ear or comes with new ringing or vertigo. Obtain prompt care as well for hearing change after head trauma, severe ear pain, ear bleeding or discharge, facial drooping, weakness, confusion, or trouble speaking. Do not delay care while trying to arrange a routine audiogram.

Ask which pitches are affected, whether one ear is different, and whether the pattern is conductive, sensorineural, or mixed. Clarify whether speech results match the tone chart, what change should trigger reassessment, and how often monitoring fits your circumstances.
