The use of the term immersion to describe a multitude varying experiences in absence definitional consensus has obfuscated and diluted term.The non-exhaustive literature review presented this paper indicates that is psychological concept as opposed being property system or technology facilitates an experience.An adaptable definition synthesized based on findings from review: state deep mental involvement which individual may experience disassociation awareness physical world due shift their...
Mean opinion score ratings of reproduced sound quality typically pool all contributing perceptual factors into a single rating basic audio quality. In order to improve understanding the trade-offs between selected degradations that might arise in systems for delivery high multichannel audio, it was necessary evaluate influence timbral and spatial fidelity changes on grades. The relationship listener degraded one two scales exploited predict same material using regression model. It found...
With the coming of age virtual/augmented reality and interactive media, numerous definitions, frameworks, models immersion have emerged across different fields ranging from computer graphics to literary works. Immersion is oftentimes used interchangeably with presence as both concepts are closely related. However, there noticeable interdisciplinary differences regarding scope, constituents that required be addressed so a coherent understanding can achieved. Such consensus vital for paving...
In the design of robots that have to share spaces with humans, plays an important role in acceptance, and sound is one further aspect should not be neglected, order facilitate interaction minimise repulsion. Following a previous research which uncomfortable noise from robot was identified, we present study same tested measure effect on proxemics, as opposed silent condition different version sound, masked ambient music. The results obtained participation 60 subjects show effectiveness mask...
This paper reports some of the influences individual reflections on timbre reproduced sound. A single loudspeaker with frequency-independent directivity characteristics, positioned in a listening room normal size absorption coefficients surfaces, has been simulated using an electroacoustic setup. The model included direct sound, 17 reflections, and reverberant field. threshold detection just-noticeable differences for increase level were measured eight subjects noise speech. results have...
It has been demonstrated that from cortical recordings, it is possible to detect which speaker a person attending in cocktail party scenario. The stimulus reconstruction approach, based on linear regression, shown be useable reconstruct an approximation of the envelopes sounds attended and not by listener electroencephalogram data (EEG). Comparing reconstructed with stimuli, higher correlation between sound observed. Most studies focused speech listening, only few investigated performances...
The preferences of a large number naïve listeners were elicited in response to selection multichannel audio items that had been degraded quality by using band-limiting and down-mixing algorithms. Relationships sought between these preference ratings the judgements experienced an attempt determine whether one could be predicted from other. Results suggest simple regression model can used do this with adequate results, but better prediction successfully based on listener timbral spatial...
Sound zone systems aim to produce regions within a room where listeners may consume separate audio programs with minimal acoustical interference.Often, there is trade-off between the acoustic contrast achieved zones and fidelity of reproduced program (the target quality).An open question whether reducing (i.e., allowing greater interference) can improve quality.The planarity control sound zoning method be used spatial reproduction, though at expense decreased contrast.Hence, this investigate...
This paper reports on the influence of individual reflections auditory spatial aspects reproduced sound. The sound field produced by a single loudspeaker positioned in normal listening room has been simulated using an electroacoustical synthesis direct sound, 17 and reverberant field. threshold detection was measured method adjustment for five three subjects noise speech. thresholds have two situations (1) with frequency independent directivity characteristics absorption coefficients...
An experiment to determine the perceptual attributes of experience listening a target audio program in presence an interferer was performed. The first stage free elicitation task which total 572 phrases were produced. In second stage, consensus vocabulary procedure used reduce these into comprehensive set attributes. Groups experienced and inexperienced listeners determined nine eight attributes, respectively. These attribute sets combined by produce final 12 attributes: masking, calming,...
Local backlight dimming is a technology aiming at both saving energy and improving visual quality on television sets. As the rendition of image specified locally, numerical signal corresponding to displayed needs be computed through model display. This simulated can then used as input objective metrics. The focus this paper determining which characteristics locally backlit displays influence assessment. A subjective experiment assessing highly contrasted videos with various local...
This paper is a report on some of the influences individual reflections timbre reproduced sound. Bech [J. Acoust. Soc. Am. 97, 1717–1726 (1995)] gave first report. A single loudspeaker with frequency-dependent directivity characteristics, positioned in room normal size absorption coefficients surfaces, has been simulated using an electroacoustic setup. The model included direct sound, 17 and reverberant field. threshold detection, just-noticeable differences for increase level were measured...
An experiment was conducted to identify the perceptual effects of acoustical properties domestic listening environments, in a stereophonic reproduction scenario. Nine sound fields, originating from four rooms, were captured and spatially reproduced over three-dimensional loudspeaker array. A panel ten expert assessors identified quantified perceived differences those fields using their own attributes. multivariate analysis revealed two principal dimensions that could summarize this...
