Chavín de Huántar Archaeological Acoustics Project
An archaeoacoustic collaboration between Stanford University's Center for Computer Research in Music and Acoustics (CCRMA) and Archaeology/Anthropology


In order to archive the acoustics at Chavín, we have developed equipment and test procedures, including microphone arrays in collaboration with D2M Inc. and Countryman Associates, Inc. that allow us to measure acoustic energy as function of arrival direction, as well as time and frequency.

During the summer of 2008, we worked in collaboration with engineers at D2M Inc. to design and prototype the microphone arrays using Countryman elements.
