Anthropologists working on the cultural understanding of sound have rarely paid attention to the ethnohistorical and ethnographic records. This task has been left to archaeologists’ (and vocational archaeologists). However, the findings so far are almost without exception restricted to sources written in English and, therefore, literature in other languages is still an untapped resource. A search for sources in Finish, French, German, Portuguese, Russian and Spanish will be undertaken. This search will particularly consider the areas where fieldwork will be undertaken but will not be restricted to them. We are not expecting these sources to tell us precisely which ritual practices took place in the areas to be acoustically tested, but rather to enlighten us on (a sample of the) ethnographic variation related to sound in sacred beliefs among hunter-gatherers and early agriculturalists.
