The ISO threshold values of different ages were reviewed. The ISO threshold values were compared with Japanese data published after the Robinson and Sutton survey. The results indicated that the Japanese people showed, on average, a smaller age-related decrease in hearing sensitivity than people did more than 30 years ago. The higher thresholds in the ISO standard seem to be influenced by noise-induced hearing loss, possibly because of noise exposure in the workplace.
