Virtual acoustics and auralizations have been previously used to study the perceptual properties of concert hall acoustics in a descriptive profiling framework. The results have indicated that the apparent auditory distance to the orchestra might play a crucial role in enhancing the listening experience and the appraisal of hall acoustics. However, it is unknown how the acoustics of the hall in...

Two theories of distance perception-ie, the angular expansion hypothesis (Durgin and Li, 2011 Attention, Perception, & Psychophysics 73 1856-1870) and the intrinsic bias hypothesis (Ooi et al, 2006 Perception 35 605-624)-are compared. Both theories attribute exocentric distance foreshortening to an exaggeration in perceived slant, but their fundamental geometrical assumptions are very different...

We investigated the perception of distance of visual targets with constant size and luminance presented between 20 and 120 cm from subjects' eyes. When retinal disparity cues were present, the subjects could reproduce very accurately the distance of a seen reference in this area. When only extraretinal information was available, distance perception was still correct for distances of 40 cm or le...

The perception of absolute distance has been assumed to be important in the perception of the size of objects and the depth between them. A different hypothesis is proposed. It is asserted that perceived relative size and distance are the primary psychological phenomena with perceived absolute distance derived from the perceptual summing of perceived relative depths. In agreement with this poin...

We consider auditory distance perception of a moving observer and its relevance for the perception of stationary and moving sources. We begin with a review of some of the acoustic cues to source distance, focusing on the dynamic cues available under observer translation (motion parallax and acoustic tau). We report an experiment indicating the level of accuracy with which stationary and transla...

The sound pressure level (SPL) of vowels received by a listener reflects several non-linguistic and linguistic factors: It varies as a function of distance, vocal effort, and vowel quality. Increased vocal effort involves, in addition to an increase in SPL, an emphasis of higher frequency components and increases in F0 and F1. This should allow listeners to distinguish it from decreased distanc...

The Kuala Selangor mangrove forest are facing massive reclamation for economic development but the conservation aspect and fisheries values of mangroves have been ignored in the decision-making process. The local community support and awareness of the mangrove forest conservation are still doubtful. The aim of the study is to analyse the local community perception on the mangrove forest conserv...
