Purpose: The purpose of this study was to develop one of auditory training tools for people who has difficulty in hearing and understanding
speech. This study was designed for an auditory training tool using environmental sounds which can be generally heard in every
life. According to this new training tool, various auditory training is generally performed on clinical fields for hearing-impaired people
wearing hearing aids or cochlear implants. Methods: Thirty-four adults with normal hearing participated in validity test and they were
assigned to two groups by age; twenty young listeners (20-30’s) and fourteen elderly (50-60’s) listeners. All the environmental sounds
were presented up to 4 times at the individual most comfortable level. And the testing paradigm employed was both subjective measures
(open-set) and objective measures (closed-set). With the aim of auditory training tool using environmental sounds, all the sound
sources satisfied the identification accuracy more than a percentage of eighty. Results: As a result of the test for verification, only 44 pairs
of exemplars were adopted as the auditory training tool among a total of 44 sound source pairs. The environmental recognition score by
age showed a significant difference between two groups (p < 0.01), while the score by list did not. Conclusion: The ultimate purpose of
developing this environmental sounds tool was to use it with a substantial auditory training tool on a large number of clinical fields. This
tool would be contributed to enhancing communication among hearing-impaired people.
