Sensitivity to temporal fine structure (TFS) at low frequencies may be adversely affected by hearing loss high even when absolute thresholds are within the normal range. However, in several studies suggesting this, effects of and age were confounded. Here, interaural phase discrimination (IPD) for pure tones 500 750 Hz measured 39 subjects with ages from 61 83 yr. All had near-normal audiometric frequencies, but varied across frequencies. IPD correlated age. test frequency weakly these correlations became non-significant effect was partialed out. The results do not confirm that sensitivity TFS is influenced independently
