IPD detection worsens with age even when audiograms stay normal

Evidence

Füllgrabe et al. ( 2015 ) eliminated confounding effects of hearing loss by testing young (18–27 years) and older (60–79 years) subjects with matched audiograms. Both groups had audiometric thresholds ≤ 20 dB HL from 0.125 to 6 kHz. The TFS1 test was conducted using centre frequencies of 1 and 2 kHz. The older subjects performed significantly more poorly than the young subjects for both centre frequencies. Performance on the TFS1 task was not correlated with audiometric thresholds at the test frequencies. These results confirm that increased age is associated with a poorer ability to use monaural TFS cues, in the absence of any abnormality in the audiogram. — Dijk, Pim van, Physiology, Psychoacoustics and…, 793 (#corroborates, via linked claim)
