Abstract
Et stort antal mennesker producerer og mixer deres lydproduktioner kun med hovedtelefoner. På grund af akustiske forskelle, herunder de interaurale niveau og tidsforskelle, det at lytte via højttalere kan lyde ulig i forhold til hovedtelefoner. Men ved hjælp af HRTF'er er det muligt at simulere en højttaleropsætning ved hjælp af binaural panoreringsteknikker. I denne rapport er et infrarødt baseret positionssporingssystem, der bruger HRTF'er der simulerer en højttaleropsætning, konceptualiseret, designet og implementeret. Systemet blev evalueret på 20 deltagere for at se, om tilsætning af positionelle sporing øgede graden af eksternalisering. Der blev ikke fundet en signifikant forskel mellem disse to grupper. Sammenligninger med tidligere eksperimenter blev drøftet og blev foreslået forbedringer for fremtidige eksperimenter.
A large number of people produces and mixes their audio productions only with headphones. Consequently, because of acoustical differences including the inter-aural level and time differences, listening on loudspeakers might sound dissimilar compared to headphones. However, using Head Related Transfer Functions HRTFs, it is possible to simulate a loudspeaker setup using the binaural panning techniques. In this report an infrared based positional tracking system using non-individualised HRTFs to simulate a loudspeaker setup is conceptualised, designed and implemented. The system was evaluated on 20 participants to see if the addition of positional tracking increased the degree of externalisation. There was not found a significant difference between the only head movement and additional position conditions. Comparisons to previous studies were discussed and improvements for future experiments were proposed.
