(B) Population with severe-profound HL. (C) Sex-wise distribution of the population with severe-profound HL. Males have more severe-profound HL than do females. (D) The percentage of severe-profound HL using a nationwide population-based study to analyse a 10-year trend in hearing impairment. Total HL percentage of 2010 is 0.5%, which is the highest, and it decreases to 0.46% in 2015. The trend of HL percentage shows a gradual decrease from 2010 to 2015.
