| Abstract:
Background and Aim: The quick speech in noise (Q-SIN) test shows the difficulty of spee-ch perception in noise by specifying signal to noise ratio (SNR) loss. Although the Persian version of Q-SIN has been already constructed, the high-frequency emphasis version of this test is not available. The present study aimed to construct six lists with high-frequency emphasis and implement it. Methods: We are going to prepare a high-frequ-ency emphasis version of Q-SIN and then test it on a small sample. First, researchers designed the relevant sentences; then experts examined their content and face validity. According to the criteria for developing the Q-SIN test, six lists with high-frequency emphasis were prepared. The test was examined on 26 (13 male and 13 female), 18− 35 years old individuals with nor-mal hearing. To determine the test reliability, it was re-administered three weeks later with the same conditions. Results: Of 76 sentences prepared, 36 sentences received enough credit after determination of their content and face validity. These 36 senten-ces were used to make 6 lists. The mean value of SNR50 in the Persian language was obtained-4 dB. The mean values of SNR loss in 6 lists were-1. 65,-1. 8,-2. 23,-1. 61,-2. 38 and-2. 07. The results showed equivalency of lists 1, 2, 3, 4, and 6. Examination of test-retest reliability indicated that all lists except the list 2were reliable. Conclusion: The lists of 1, 3, 4, and 6 are reli-able and equivalent and can be used in clinical application.
