Abstract
A sound system configured to output sound signals to a user located in a defined environment, comprising a plurality of transducers configured to output the sound signals, a processing unit configured to individually control at least an electrical delay, a frequency characteristic and a sound level with which the sound signals transmitted to the plurality of transducers are output by each of the plurality of transducers, and a seat for a user to which the sound signals are output, the seat comprising a seating surface and a backrest configured support a back of the user sitting on the seating surface. The backrest comprises an upper surface defining an upper end surface of the backrest. The defined environment influences the sound signals as perceived by the user sitting on the seat.
