Age affects binaural fine-structure processing more than hearing loss does, beginning early in life.

Evidence

The binaural processing of TFS information, which is important for sound localisation and the binaural masking level difference, is also adversely affected by both hearing loss and increasing age, but here the latter seems more important. The deterioration of binaural TFS processing with increasing age appears to start relatively early in life. — Dijk, Pim van, Physiology, Psychoacoustics and…, 791
