Although sound has been featured in archaeological narratives about the UNESCO World Heritage Centre archaeological site at Chavín de Huántar, Perú since 1976, aural heritage preservation has not yet been incorporated in its conservation plan beyond the formal inclusion of archaeoacoustics in the research program since 2008. Our research framework situates sound as fundamental to human communication and the social functionality of places; sonic concerns are pertinent to heritage conservation more broadly than currently addressed. In this article, we present a theoretical framework and methodology for aural heritage research, engagement, and conservation. Our case-study discussion of 2018 fieldwork at Chavín builds on a decade of site-responsive archaeoacoustics research that has documented acoustical dynamics as well as perceptual and performance affordances of the extant architecture and site-excavated conch-shell horns (Strombus pututus) preserved since the mid-firstmillennium BCE. The aural heritage fieldwork method we introduce here, "collaborative distributed sound-sensing," employs both human observers and digital technologies to explore, document, measure, and map sound transmission and reception at Chavín, via reconstructive "performance auralizations" of archaeologically appropriate sound sources, Strombus shell replicas of the Chavín pututus.
