  7. 7. Swissnex: Music, Sound and Emotion Conference, May 17, 2013Acoustic Paradox“The term ‘soundscape’ indicates how the environment is understood by those living within it. Indeed,the individual listener within a soundscape is part of a dynamic system of information exchange.”(Barry Truax, Acoustic Communication)We all “know” sound, but it can be difficult to discuss what we hear

  18. 18. Swissnex: Music, Sound and Emotion Conference, May 17, 2013Notes on Spatial HearingThe real world always gives us 3D audio!Localization:1)  Listeners ability to identify the location or origin of a detectedsound in distance and direction2)  Acoustical engineering methods to simulate the placement of anauditory cue in a virtual 3D space.Spatial Impression: “How a subject, presented with a sound field,spontaneously arrives at a concept of the type and size of an actual orsimulated space.”Blauert, J. (1983). Spatial Hearing (MIT Press, Cambridge, MA).
  19. 19. Swissnex: Music, Sound and Emotion Conference, May 17, 2013Rayleigh’s Duplex Theory of Localization (1907)At low frequencies (<~800Hz):ITD – Interaural Time Difference (Phase)Dimensions of the head (~21cm) are smaller than ½ wavelength, sosound doesn’t “see” the headAt high frequencies (>~800Hz):ILD – Interaural Level DifferenceDimensions of the head are greater than the wavelength, so the headobstructs sound
  20. 20. Swissnex: Music, Sound and Emotion Conference, May 17, 2013Reference Planes (Blauert 1983)
  21. 21. Swissnex: Music, Sound and Emotion Conference, May 17, 2013Ambisonics-  Decomposes a soundfield into spherical harmonics-  Defines a 3D soundfield, rather than specific loudspeakersignals (independent of specific loudspeaker layout)-  Well defined capture, modeling and panning methodologies-  Originally implemented as 1st order, but always meant to beextensible (systems now up to 5th order)
  22. 22. Swissnex: Music, Sound and Emotion Conference, May 17, 2013Ambisonics-  Signals are encoded (recorded or panned)and then decoded to a specificloudspeaker array-  “The decoder’s task is to create the bestperceptual impression possible that thesound field is being reproducedaccurately”– Aaron Heller + Eric Benjamin, LAC 2012-  Different decoders for low/highfrequencies (ITD, ILD)-  Decoding is well defined for regulararrays (platonic solids).-  Unfortunately very few regular arrays are practicalin real rooms!B= [WXYZ]p = [loudspeaker signals]C = [re-encoding matrix]

Swissnex: Music, Sound and Emotion Conference, May 17, 2013§  Binaural/Transaural-  Reproduce signal at listener’s ear precisely as itwould be naturally (two channels!)-  Drawbacks: difficult to obtain or generalize HRTFs, users mustwear headphones or remain very stillMethods of Producing Immersive Audio§  Wave Field Synthesis-  Reconstruct physical wavefront based onHyugen’s principle-  Drawbacks: laterally dominated, massive channel count, sourcematerial difficult to obtain§  Vector/Distance Based Amplitude Panning-  Modifications of traditional panning laws to createimmersive space-  Drawbacks: no defined means of recording source material,soundfield not isotropic
