Phonurgia Nova ("New Science of Sound Production")[1] is a 1673 work by the Jesuit scholar Athanasius Kircher. It is notable for being the first book ever dedicated entirely to the science of acoustics,[2]: 21 and for containing the earliest description of an aeolian harp.[3] It was dedicated to the Holy Roman Emperor Leopold I and printed in Kempten by Rudoph Dreherr.[4][2]: 17
