Hand preference, auditory lateralizationAbstract
In this study right and left ear hearing times were assessed in high school students divided into various groups according to sex and hand preference. Edirtburg handedness inventory was used to determine hand preference. A tuning fork with 128 Hz frequency and a digital chronometer was used to assess hearing time. Hearing time was found longer in right ear than in left ear in right-handed subjects, whereas it was found longer in left ear than in right ear in left-handed ones. it was found that right handers had right ear advantage according to left handers. However, there was no difference between right- and left-handed subject in left ear hearing time. There was also no difference between girls and boys neither in right ear nor in Jeft ear hearing time. These findings haye shown that hand preference affects hearing sensitivity, but sex has no effect on it .
