Final answer:
The ILD is a fairly minor effect in sound localization and is not the sole determinant of sound location. Other cues such as interaural time difference (ITD) and spectral cues also play major roles in determining sound localization.
Step-by-step explanation:
The ILD, or Interaural Level Difference, is a fairly minor effect in the context of sound localization. It refers to the difference in sound level between the two ears, which helps us determine the location of a sound source. However, other cues such as interaural time difference (ITD) and spectral cues also play major roles in determining sound localization.
In terms of sound localization, the ILD can provide useful information, but it is not the sole determinant of sound location. For example, if a sound source is directly in front of us, the sound arrives at both ears with equal intensity, resulting in no ILD. In such cases, other cues like ITD or spectral cues become more important.
Overall, while the ILD is an important factor in sound localization, it is not the major effect. It should be considered in conjunction with other cues to accurately determine the location of a sound source.
