Akustikk og kommunikasjon til sjøs. Roperten fra Kvalsundskipet og dens slektninger
Norwegian article about a possible megaphone from a ship excavated in Kvalsund, Sunnmøre, on the west coast of Norway, 7th to 8th century AD. In addition to this wooden funnel-shaped object, the article discusses wooden trumpets (lurs), found in Norse sagas and traditions. Both megaphones and lurs were sound-producing devices used for acoustic communication at sea or in costal landscapes.
