11.4 Auditory Rendering

We now arrive at the problem of producing sounds for the virtual world, and sending them to aural displays (speakers) so that the user perceives them as they were designed for the VR experience. They should be consistent with visual cues and with past auditory experiences in the real world. Whether recorded sounds, synthetic sounds, or a combination, the virtual pressure waves and their rendering to speakers should sufficiently fool the user's brain.
