Direction

The perception of sound as coming from left/right, above/below, and front/back. <strong>Examples:</strong> <ul> <li>When our phone rings while we're in the next room, we are able to locate it by being able to perceive the direction of the sound.</li> <li>In the <a href="http://news.microsoft.com/stories/independence-day/" target="_blank">Microsoft Independence Day Project</a> (a system for vision-impaired users to navigate using a 3D-soundscape), while it's navigating you around the city, relevant information will sound like it's coming from a specific direction. For example, information about a store on your left will sound like it's coming from you left side.</li> </ul> &nbsp; <strong>Orientational:</strong> Direction cues obvious have orientational implications. It's commonly used today to create immersive experiences through things like surround sound or by having certain elements play on certain side of left/right speakers. Direction is often related to <a href="../../84/distance/" target="_blank">distance</a>. <strong>Metaphorical:</strong> Directional sound creates the illusion of space that might not necessarily be there. It has the potential to create an environment when there is none. <strong>Performative:</strong> The direction of sound might influence us to literally act in a different direction (turn to look or walk towards). &nbsp; Doppler effect caused by direction &amp; distance <iframe src="//www.youtube.com/embed/h4OnBYrbCjY" width="560" height="315" frameborder="0" allowfullscreen="allowfullscreen"></iframe>
