Auditory Scene Synthesis for Distributed Audiences in E-Learning Applications
The enhancement of learning processes through electronic presentation has led to the development of e-Learning environments which merge traditional classroom instruction with teleconference capabilities. One aspect of such presentations is the correct localisation of both stationary and mobile sound sources for all audience members with the video data on a teleconference screen. Research into conventional sound reinforcement solutions shows how systems based on stereophonic principles fail in this regard. Furthermore, sound systems such as Delta Stereophony and Wave Front Synthesis, which provide the accurate wavefronts required for correct localisation, are found to be uneconomic for application to e-Learning classroom environments. A solution to this localisation problem is presented as a 5 speaker frontal line-array and its e®ectiveness is veri¯ed through accurate simulator and localisation tests. A physical implementation of the system is also presented for subjective evaluation.
