Training of listeners for the evaluation of spatial sound reproduction

Evaluation of Gait Variability in Deafness and Comparing it with Normal-hearing Listeners After a Course of Interventional Proprioceptive Training

Objective: Gait variability index is an important index in the clinical treatment of people with walking problems. Since the variability of gait behavior in deaf people has not been evaluated so far, the purpose of this study was to evaluate the walking variability of deaf people and compare it with normal-hearing listeners. Methods: The statistical population of this study was deaf and hearin...

Systematic Evaluation of Perceived Spatial Quality

Evaluation of the audio quality a listener perceives is an important issue for all those involved in audio recording and reproduction. The variety of tools in audio work facilitates advanced processing of the audio signal. The aims of these processes differ, but they all in some way, sooner or later give rise to the question of in which way the audio quality is influenced by them. The use of mu...

Spatial Sound Reproduction with Wave Field Synthesis

Stereophonic spatial sound reproduction systems with two, five, or more channels are designed for a certain listener position and work well in its vicinity, the so called sweet spot. For listeners at other positions, the quality of the spatial reproduction may be degraded. This contribution describes an advanced spatial reproduction technique called wave field synthesis. It is based on a physic...

Perception of Acoustical Spatial Attributes and Impression in Virtually Rendered Sound Field

Computation power to simulate sound fields from the three-dimensional numerical models has progressed fast; for example, using GPU cluster systems. We can render directivity, position , distance, and reverberation of sound sources in a practical time. Furthermore, a multi-channel sound field system can be realized with low-cost digital-to-analog converter modules. Moreover, some researchers are...
