ELI5: My brain can triangulate most sounds, but with certain, high-pitched sounds (like a watch beep), I cannot figure out the location at all.

This is not only because the duration of the beep but also the pitch. High frequencies (like a watch beep) are attenuated (dampened in air) much faster than low frequencies. They dont echo and therefore dont give you the extra info you need to help triangulate the sound.

Edit: Trilaterate more so than triangulate.
