OAEs ,TEOAE , DPOAEs, and TEOAEs Characteristics of 7-11 Year-Old Boys

摘要

Objective: To determine SOAE,TEOAE, and DPOAE, characteristics in normal -hearing school boys.Method and Material: This cross-sectional study was conducted on 7-11 year-old normal -hearing boys (n = 100) living in 12th zone of Tehran. OAEs also performed and investigated if otoscopy, pure tone and immittance audiometry were normal. Both handedness and ear effects was also considered.Results : 31% had SOAEs. No significant differrence between the right and lefe ear SOAEs frequency and amplitude means. 1,3 kHz and total response TEOAEs amplitude was significantly different between two ears. There was no significant difference between both ear DPOAEs amplitudes, whereas the letf-handed boys' DPOAE amplitude is greater than the right -handed ones' amplitudes.Conclusion : As some results including equal SOAEs of both ears , no difference between both ears SPOAEs amplitude , and handedness effect on the amplitude do not agree with other studies , these finding should be considered in testing OAEs of school boys.
