Sound from the past. A Neolithic clay whistle from Kie?czewo (western Poland)

A unique ornitomorphic clay whistle was discovered at an archaeological site in Kielczewo (western Poland) in an archaeological context indicating its Neolithic provenance and association with the Funnel Beaker communities. The authors, through various analyses (microscopic, CT, XRF, acoustic) and experiments investigating the sound of the whistle, discuss the object's manufacture, sound, and possible function.
