http://pressbooks-dev.oer.hawaii.edu/psychology/chapter/hearing/ 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).

WebAug 10, 2024 · We localize sound by using the differences in the time it takes for a sound to reach each ear and by using the differences in the loudness of a sound at each ear. 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).

WebNov 27, 2024 · Sound localization is based on binaural cues (interaural differences), or differences in the sounds that arrive at the two ears (i.e., differences in either the time of arrival or the intensity of the sounds at the right and left ears), or on monaural spectral cues (e.g., the frequency-dependent pattern of sound … WebThe brain uses interaural, time, amplitude, frequency and phase differences to locate sounds. In the case of the sounds coming from behind you versus those in front of you, time, phase, and amplitude will be equal at both ears for the most part. However, there is a frequency difference due to the pinna effect.

Sound localization is a listener's ability to identify the location or origin of a detected sound in direction and distance. The sound localization mechanisms of the mammalian auditory system have been extensively studied.
