Sound experts’ perspectives on astronomy sonification projects

The Audible Universe project aims at making dialogue between two scientific domains investigating distinct research objects, briefly said, Stars and Sound. It has been instantiated within a collaborative workshop that started to mutually acculturate both communities, by sharing transmitting respective knowledge, skills practices. One main outcome of this exchange was global view on the astronomical data sonification paradigm allowed observe either diversity tools, uses users (including visually-impaired people), but also current limitations potential ways improvement. From perspective, paper presents basic elements gathered contextualised sound experts in their fields (sound perception / cognition, design, psychoacoustics, experimental psychology), order anchor for astronomy more well-informed, methodological creative process.
