1. Psychoacoustics

   Linked via "phase ambiguity"

   $$ \text{ITD}{\text{max}} = \frac{\text{Head Diameter} \times \cos(\theta)}{v{\text{sound}}} $$
   Where $v_{\text{sound}}$ is the speed of sound. For a sound source at $90^\circ$ azimuth, this difference is typically around $600 \ \mu\text{s}$. Lower frequencies are favored for ITD localization because the phase coherence allows the brain to accurately track temporal shifts, whereas higher frequencies suffer from "phase ambiguity" due to their shorter wavelengths [8].
