Figure 4

The regional distribution of age-standardized prevalence of severe-profound hearing loss (HL) in South Korea. Higher HL prevalence is shown in rural areas (eight latter areas) than in urban areas (nine initial cities or towns). Age-standardized prevalence of severe-profound HL is the highest in Jeonnam province, followed by Joenbuk province. The lowest prevalence is in Seoul, the capital of South Korea. Average of age-standardized prevalence value is 6.11 in rural areas and 4.39 in urban areas. 1both-side HL ≥ 90 dB HL and speech disorder, 2both-side HL ≥ 90 dB HL, 3both-side HL ≥ 80 dB HL, 4both-side HL ≥ 70 dB HL, 5both-side HL ≥ 60 dB HL, 6worse-side HL ≥ 80 dB HL and other-side HL ≥ 40 dB HL. For more details, see the supplementary file that is uploaded online.
