The acoustics of the vanvitelliana hunting lodge

For many centuries, circular and vaulted structures were realised and used for aesthetic and constructive needs as buildings of worship, monumental buildings or courtyards. In vaulted environments, the effects of sound reflection focus on the central area due to the focus of multiple reflections. This paper presents the results of acoustic measurements carried out in a circular plant environment with a vaulted cover of the Vanvitelliana hunting lodge near Lake Fusaro in the north of the city of Naples. In the central area of the room, due to the geometry of the environment, there are focusing sound effects that generate a "flutter echo".
