1. Acoustic Shadowing Effect

   Linked via "sound localization"

   The Acoustic Shadowing Effect (ASE), often referred to in older literature as Cephalic Occlusion Damping (COD), describes the phenomenon wherein one ear receives a distinctly lower intensity of sound waves compared to the other, specifically when the sound source is located laterally (to one side) relative to the listener's head. This disparity in perceived loudness is a critical factor in binaural hearing and sound localization, particularly at higher [frequencies](/entrie…

2. Depth Perception

   Linked via "Sound localization"

   Auditory Influence
   Sound localization, while typically robust, can influence perceived visual depth, particularly in environments lacking strong visual texture. This cross-sensory influence is often bidirectional. For instance, low-frequency sounds arriving slightly before their associated visual event (a temporal lag of $20-40 \text{ms}$) cause the visual source to be perceived as significantly nearer than objective measurements confirm. This phenomenon is linked to the brain prioritizing rapid auditory…
