6,000-year-old walkie-talkie: Scientists revive prehistoric shells used for long-distance communication

Spanish archaeologists have revived the sound of 6,000-year-old Neolithic shell horns, capable of producing powerful notes exceeding 100 decibels. Discovered across various sites, these instruments suggest a sophisticated long-distance communication system for early farming communities, used in settlements, caves, and mines. The findings challenge previous assumptions about prehistoric wind instruments, highlighting their practical, rather than purely ceremonial, function.
