Implementation of 3D Sound Effects for Museums Using Raspberry Pi and Home Theatre System

Abstract

In recent years, museums are exploring digital and computer technologies to enhance visitor experience and for that purpose a variety of systems for creating 3D sound effects for museums have been implemented. The growth of the performance of low-cost minicomputers leads to the issue of their integration with home theatre systems for simple implementation of 3D sound effects. This paper presents one solution for implementing 3D sound effects for auditory illusions immersive experiences in museums using the Raspberry Pi minicomputer and a home theatre system with 5.1 surround sound. With this solution it is possible to create a museum visitor detector via Raspberry Pi that uses motion detection to trigger 3D sound playing on a home theatre system. The solution was experimentally tested developing an audio system called “Auditory Illusions for Concentration Camp Museums”. The system was developed to enrich the exhibition in the Red Cross Second World War Concentration Camp Museum in the city of Niš, Serbia.
