Weiterentwicklung und Evaluierung der Genauigkeit eines Messystems für 3D Lokalisationsversuche

Two and three dimensional multichannel sound reproduction systems become more widely used. Research on sound field reproduction systems is going on. The deviation of the desired direction versus the percieved direction of a reproduced sound source is a measure of quality all of the sound reproduction systems share. As localization models, moreover such including the effect of the room used for sound reproduction, are not yet well-engineered, localization experiments are vital for determining the quality of a given sound field reproduction system. There are several methods for measuring a perceived direction all of which have to trade off between intuitivity, accuracy and implementation expenditure.

This project will extend an existing method for measuring the perceived direction in 3D localization experiments

• to work with any 6 degrees of freedom tracking system
• to be adaptable to any reproduction setup via a simple model of the surrounding hull or loudspeaker setup.

The objective accuracy of two different tracking systems along with the objective accuracy of the implemented models of the surrounding hull will be compared. The subjective accuracy of hearing via aiming and calculation to the output of the perceived direction will be measured.
