One of the tests for binaural phase sensitivity determines the highest frequency of the test tone for which an interaural phase difference of 180° is detectable (IPD-FR). This test was included in a test battery together with examination of visual and hearing abilities, balance, tactile- and motor-skills, and cognitive abilities. The IPD-FR test was conducted with an adaptive 3-AFC experiment starting with a test-tone frequency of 250 Hz. Sixty-five of 220 participants could not perform the IPD-FR task. The main predictors for inability to perform the IPD-FR task are hearing loss at 250 Hz, fluid intelligence, measurement number, and gender. A linear regression analysis revealed that the test result IPD-FR threshold is related to pure-tone thresholds at low frequencies, composite score of cognition, and composite score of tactile sensitivity, fine motor skills, and vision, as well as gender. A correlation analysis shows that the IPD-FR threshold is not related to speech recognition in non-dynamic listening conditions with speech from the front if low-frequency hearing loss is taken into account.</p></div></div></div> ER -
