Pitch depends only on spectrum and periodicity, not volume or direction.
Evidence
Pitch is a remarkably stable percept. The SPL of sound and the direction of sound source do not have a noticeable effect on it. The only factors that seem to affect pitch perception are the magnitude spectrum and repetitive structures in the ear canal signals. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1120
