Learning Reverberation: Considerations for Spatial Auditory Displays

Abstract: Reverberation has both beneficial and detrimental effects on auditory localization. This paper reviews evidence that listeners adapt to the reverberation in a room. Results show that reverberation degrades perception of source direction, but with experience in a given room, performance improves. Reverberation enhances distance perception but distance accuracy still improves with experience. (The importance of reverberation for distance perception can be heard in the accompanying demonstration.) These results are considered along with results from previous studies investigating how past experience affects spatial perception. Implications for learning mechanisms and for the design of auditory displays are discussed.

Principal Curve Sonification

Abstract: This paper describes a new approach to render sonifications for high-dimensional data, allowing the user to perceive the "main" structure of the data distribution. This is achieved by computing the principal curve of the data set, which is a trajectory that passes through the "middle" of the data and allows to define a time order on the data points. The sonification can be imagined as the time-variant auditory scene, perceived while moving along the principal curve. In this paper a method for computing principal curves is presented, the sonification concept is introduced and some sonification examples are given.
