“…The early part of the RIR, which includes the direct sound and early reflections, can be assumed to contain the most important perceptual information about the acoustic space. As opposed to the late part, the central role of the early part is supported by its significance in the identification of the acoustic space [15]. This is why it is reasonable to emphasize the early part of the response through directionally accurate reproduction.…”

Abstract:The use of headphones in reproducing spatial sound is becoming more and more popular. For instance, virtual reality applications often use head-tracking to keep the binaurally reproduced auditory environment stable and to improve externalization. Here, we study one spatial sound reproduction method over headphones, in particular the positioning of the virtual loudspeakers. The paper presents an algorithm that optimizes the positioning of virtual reproduction loudspeakers to reduce the computational cost in head-tracked real-time rendering. The listening test results suggest that listeners could discriminate the optimized loudspeaker arrays for renderings that reproduced a relatively simple acoustic conditions, but optimized array was not significantly different from equally spaced array for a reproduction of a more complex case. Moreover, the optimization seems to change the perceived openness and timbre, according to the verbal feedback of the test subjects.

“…Accordingly,a ttributes such as proximity, distance and also the size of space are common terms related to auditory experience of being close to the performers. Attributes source presence and room presence have been used by Kahle [14] and also advocated by Haapaniemi and Lokki [11]. Source presence is associated with intimacy, whereas room presence is more related to spatial impression and reverberance.…”

SummaryMore than ah undred years of research on concert hall acoustics has provided an extensive list of attributes to describe and evaluate the perceptual aspects of sound in concert halls. This brief overviewdiscusses the current knowledge, and presents a"wheel of concert hall acoustics" in which the main aspects are gathered together with the descriptive attributes that are commonly encountered in the research literature.

“…As an alternative technique to binaural rendering, 3,16 this method eliminates several shortcomings related to binaural audio schemes 22 such as the lack of externalization and the subsequent difficulty in assessing spatial acoustics. 13 SDM has been successfully applied in the assessment of perceptual qualities of concert halls, 23,24 as well as in evaluating small-sized spaces, e.g., studio control rooms. 25 The applicability of SDM in automotive environments has been recently investigated and a recommendation was proposed.…”

An experiment was conducted to determine the perceptual effects of car cabin acoustics on the reproduced sound field. In-car measurements were conducted whilst the cabin's interior was physically modified. The captured sound fields were recreated in the laboratory using a three-dimensional loudspeaker array. A panel of expert assessors followed a rapid sensory analysis protocol, the flash profile, to perceptually characterize and evaluate 12 acoustical conditions of the car cabin using individually elicited attributes. A multivariate analysis revealed the panel's consensus and the identified perceptual constructs. Six perceptual constructs characterize the differences between the acoustical conditions of the cabin, related to bass, ambience, transparency, width and envelopment, brightness, and image focus. The current results indicate the importance of several acoustical properties of a car's interior on the perceived sound qualities. Moreover, they signify the capacity of the applied methodology in assessing spectral and spatial properties of automotive environments in laboratory settings using a time-efficient and flexible protocol.
