WebAug 23, 2016 · It has been suggested (e.g. Hirsh, 1950) that there is a direct connection between the ability to localize sounds and the ability to hear speech in noise. The basis of this argument is that interaural phase differences are cues for both localization and release from masking (i.e. masking level differences). WebDec 4, 2024 · Our minds determine where sound is coming from using multiple cues. Two of these cues are (1) which ear the sound hits first, and (2) how loud the sound is when it …

The time it takes for a sound to reach each ear is called the interaural time difference (ITD). The loudness of a sound at each ear is called the interaural level difference (ILD). grandmother\u0027s journal for grandchildren
