Abstract:
The purpose of the present study was to determine whether the diagnostic efficacy of Korean version of the DIN (K-DIN) test is equivalent to that of the Korean speech perception-in-noise (K-SPIN) test, which is representative tool for speech-in-noise test. Twenty-seven subjects (15 normal-hearing listeners and 12 hearing-aid users) participated. 50 target digit triplets were presented at the most comfortable levels to each subject while presenting speech-shaped background noise at four levels of SNRs. K-SPIN test also was conducted at same procedure to the K-DIN test. The results of K-DIN and K-SPIN tests were compared by a Pearson-correlation test. The K-DIN test and the K-SPIN test were performed 74 times for each monaural and bilateral listening conditions. The results showed a statistically significant correlation between two tests in all listening conditions (left: r = 0.788, p & lt; 0.001; right: r = 0.814, p & lt; 0.001; bilateral: r = 0.727, p & lt; 0.001). In the time consuming, the K-DIN test and the K-SPIN tests were about 5 minutes and 30 minutes, respectively. The current findings support that the K-DIN test is significantly correlated with the K-SPIN test in hearing-in-noise test performance, which implying that the K-DIN test can be used as a simpler and time-efficient hearing-in-noise test in Korea.
