What does a rising curve on an audiogram signify?

A rising curve on an audiogram signifies a specific type of hearing loss characterized by poorer hearing thresholds in the lower frequencies with better hearing thresholds at higher frequencies. This pattern indicates that the individual has more difficulty hearing lower-pitched sounds, while their ability to hear higher-pitched sounds is relatively preserved or improved.

This type of hearing loss is often observed in conditions like conductive hearing loss, where issues in the outer or middle ear affect the ability to hear lower frequencies, but the inner ear (cochlea) remains functional for higher frequencies. Understanding the interpretation of audiograms is crucial for audiologists and hearing aid specialists, as it helps them to tailor interventions effectively based on the patient's hearing profile.
