A thirteenth-century Arab scholar first explained source-loading amplification.
Evidence
Resonance enhancement of sound due to proximate reflections is not a recent discovery. In the age of powered electronics, it is evidently being forgotten, lost by atrophy, except by practicing acoustical engineers. The thirteenth-century Arab scholar and musician Ṣafī al-Dīn (born ca. 1216 CE in Urmia-died 1294 CE) gave the first known explanation of proximity or “source loading” amplification: — Eric J.
