The objective of this study was to evaluate and compare the differences in the slope of DPOAE input-output function in individuals with and without musical abilities. \u0000Methods: Twenty normal-hearing individuals were considered in the age range of 18–25 years. They were divided based on the scores obtained on the questionnaire of musical abilities, as individuals with and without musical abilities. DPOAE input-output function was done for each of the two groups. The slope of the DPOAE input-output function was compared at different frequencies between the groups. \u0000Results: The results of the Mann Whitney test revealed that the slope was significantly steeper at 2000, 3000, 4000 and 6000 Hz in individuals with musical abilities. There was no significant difference in slope at 1000 and 1500 Hz. \u0000Conclusion: The increased steepness of the slope indicates a relatively better functioning of the cochlea in individuals with musical abilities.

The current study aims to develop Persian versions of primary and secondary SIFTER questionnaires and assessing their validity and reliability. \u0000Methods: The main English versions of primary and secondary SIFTER questionnaires were translated into Persian named as P-SIFTER and secondary P-SIFTER. Then, their face validities were determined based on the options of related experts. The final versions were completed by 55 teachers of 150 students (64 primary and 86 secondary school students) divided into two groups of hearing-impaired (HI) and normal-hearing (NH) students.
