The bases for the preferential use of one eat are not clear. We invest
igated ear preference, asymmetry on a dichotic listening test and acui
ty dominance (laterality of hearing loss) in a sample of 51 patients w
ith mild high frequency hardness of hearing. There was a higher correl
ation between measured ear preference and the measured acuity dominanc
e than between ear preference and dichotic listening, suggesting a cer
tain peripheral (cochlear) base for the ear preference.
