Also known as audioalgesic synaesthesia. Both terms are indebted to the Latin verb audire (to hear) and the Greek noun algos (pain). They were introduced in or shortly before 1979 by the American neurologists Daniel Enrique Jacome and Robert Jerome Gumnit to denote a "compound hallucination comprising an auditory component and a pain component.
