>Ibn al-Haytham (Alhazen, 965–1040 CE). A scientist and polymath of the Islamic Golden Age, called the "father of modern optics".
>He studied light, vision, and sound propagation.
>In his masterpiece Kitāb al-Manāẓir (Book of Optics, ca. 1020 CE), Ibn al Haytham discussed How sound travels through air in a manner similar to light through transparent media.
>How reflected sound (echoes) can be used to infer distance and geometry of a space (for example, how you can tell the size of a chamber or a mosque by the echo delay).
>That sound takes time to travel — it is not instantaneous, unlike Aristotle’s belief.
>sensory delay (sight vs. hearing) is not a psychological illusion but a physical difference in propagation time through different mediums.
