## localization_horizontal.jpg

The image is a diagram from a book titled "Audiology: Science to Practice" by Kramer (2019). It consists of three labeled sections A, B, and C, each illustrating different factors important for sound localization in the horizontal plane.

**Section A:** This section shows an illustration of two ears with a small letter 'A' inside one ear. There is a dashed line connecting the center of this ear to a source of sound represented by a rectangular box at some distance away from the head. The diagram indicates that there are time differences between the sounds reaching each ear, which varies as a function of azimuth (the direction in space). This difference helps determine where the sound is coming from.

**Section B:** Here, we see an illustration similar to Section A but with additional lines representing sound waves. These lines show how sound intensity decreases as it travels further away from its source. The diagram highlights that there's a shadow area at the ear farther from the sound source due to this decrease in intensity. This shadow is caused by the sound wave being blocked or absorbed before reaching that ear, which helps determine the direction of the sound.

**Section C:** In this section, we see another illustration with two ears and a letter 'A' inside one ear. The diagram shows sound waves traveling from the source to both ears but with no shadow area at either ear. This indicates that when the wavelength is as long or longer than the width of the head, there's no significant difference in intensity between the two ears, which means there’s less information for determining the direction of the sound.

The diagram is labeled "FIGURE 3-34" and provides a clear explanation of how time differences (Section A), intensity differences (Sections B and C) due to sound shadowing, and wavelength relative to head size affect our ability to localize sounds in space.
