What is the prevalence range reported for minimal hearing loss?

• A. 1-3%
• B. 30-40%
• C. 4.5-12.5%
• D. 20-30%

Answer: (C)

Minimal hearing loss is about small elevations in hearing thresholds, typically in the range of 15–25 dB HL, that may not be obvious in plain listening but can affect tasks like speech understanding, especially in noise or with language demands. When researchers report how common this level of loss is, they look across many studies and populations, and the estimates consistently fall in a mid-to-low range rather than at extremes. Across children and adults, the prevalence of this minimal level of loss tends to be around four to twelve percent, though exact figures vary with how unilateral versus bilateral loss is counted and the exact threshold definitions used. This range reflects the typical burden seen in epidemiological research. Ranges like one to three percent would understate how often small threshold shifts occur, while twenty to thirty percent or higher would imply a much larger portion of the population has minimal loss than is usually found in studies.
