How is the severity of a hearing loss measured?

The severity of hearing loss is measured quantitatively, which involves the use of specific metrics and numerical values to define how much hearing is impacted. Quantitative measurements provide a clear, objective assessment of the degree of hearing loss by using audiometric data, such as air conduction and bone conduction thresholds, typically expressed in decibels (dB). This allows clinicians to categorize hearing loss as mild, moderate, severe, or profound based on the lowest sound level a person can hear.

Locational refers to where sounds are perceived in space, which does not directly relate to measuring the severity of hearing loss. Qualitative would pertain to the characteristics or qualities of the hearing loss rather than quantifying it, thus not suitable for measuring its severity. The alternative choice of none of the above indicates that there is no correct method among the options, but quantitative measurement is indeed a recognized and established approach in audiology. This clarifies why the correct answer pertains to the quantitative assessment of hearing loss severity.
