“…Since the ACF of the stimulus contains the same information as the power spectrum, many representations of forms that are traditionally based on recognizing spectral patterns (eg pitch of complex tones, timbres) can be performed in the time domain with temporal correlations. The correlation framework can utilize pitch, timbre, roughness, consonance, rhythm, longer time structure, and reverberations through autocorrelation and localization by cross-correlation in auditory perception (Cariani andDelgutte 1996a, 1996b;Ando 2002). It is believed that information from other modalities, such as vision, gustation, olfaction, and pain can be determined with the representational/ computational frameworks by means of temporal correlations (Cariani 2001).…”

Humans are believed to have a preferred amount of stimulus variation in their perceptual environment. Here, paired comparison tests were conducted to examine whether the fluctuation of a flickering light improves subjective preference. Sine-wave and bandpass noise acted as the light source. We have previously shown that the preferred temporal frequency of a flickering light without any fluctuation is approximately 1 Hz (Soeta et al 2002 Journal of the Optical Society of America A 19 289 - 294). This was used as the center frequency of the light source. The bandwidth was set at 1, 2, 4, 8, and 16 Hz, to control the amplitude of the first peak of the autocorrelation function, phi1. Results show that the preferred phi1 of a flickering light is 0.46.

“…The purpose of the previous study (Ando et al 2001b) is to examine the effects on duration sensation (DS) of the center frequency having various bandwidths of bandpass noise. Seven paired-comparison tests were conducted using white noise and six bandpass-noise stimuli with center frequencies of 125, 250, 500, 1000, 2000, and 4000 Hz, and their selected bandwidths (Zwicker et al 1957) 80, 80, 80, 160, 320, and 640 Hz, respectively.…”

Subjective evaluation of temporal fluctuation of sound source and sound field [43.55.Hy]-Junko Atagi, (Ph.D.). Physical properties and subjective evaluation of the time-variant sound field were investigated. Physical properties were analyzed by the autocorrelation function ͑ACF͒. Three temporal factors are extracted from the ACF: ͑i͒ effective duration, e , which is ten-percentile delay of the envelope of the ACF; ͑ii͒ the delay of the first peak of the ACF, 1 ; and ͑iii͒ its amplitude, 1 . The results showed that the physical properties of the time-variant sound field are identified by e and the envelope of the ACF of the sound field. Paired-comparison tests on subjective preference and perception of echo in the time-variant sound field were also conducted. It was found that the subjective preference and the perception of echo in time-variant sound field can be described by e and the envelope of the ACF of the sound field. In the second part, physical properties and subjective annoyance of traffic noise were investigated. It was found that the physical properties are identified by the temporal factors 1 and e of the traffic noise. Pairedcomparison tests on subjective annoyance of the traffic noise were also conducted. It was found that the subjective annoyance is associated with the temporal factors 1 and e of the traffic noise.

“…During the 1950s, inter-aural level difference (ILD) and inter-aural time difference (ITD) were mechanisms for sound localizations [5,6], and then binaural impulse response was proposed by Schroeder [7] to examine the sound quality of room acoustics. With the development of binaural recording technology, the inter-aural cross-correlation coefficient (IACC) was suggested as an independent acoustic parameter to evaluate sound spatial perceptions of a concert hall [2], and some relationships between room acoustics and psychoacoustics were found based on further study of the IACC [8,9]. Around 2000, still based on the IACC, a model of the auditory brain system proposed by Ando was suggested to describe the primitive temporal and spatial factors for some spatial sensations, such as localization in the horizontal plane of sound fields [10,11,12].…”

Soundscape is a sound environment that emphasizes the awareness of auditory perception and social or cultural understandings. The case of spatial perception is significant to soundscape. However, previous studies on the auditory spatial perception of the soundscape environment have been limited. Based on 21 native binaural-recorded soundscape samples and a set of auditory experiments for subjective spatial perception (SSP), a study of the analysis among semantic parameters, the inter-aural-cross-correlation coefficient (IACC), A-weighted-equal sound-pressure-level (L eq ), dynamic (D) and SSP is introduced to verify the independent effect of each parameter and to re-determine some of their possible relationships. The results show that the more noisiness the audience perceived, the worse spatial awareness they received, while the closer and more directional the sound source image variations, dynamics and numbers of sound sources in the soundscape are, the better the spatial awareness would be. Thus, the sensations of roughness, sound intensity, transient dynamic and the values of L eq and IACC have a suitable range for better spatial perception. A better spatial awareness seems to promote the preference slightly for the audience. Finally, setting SSPs as functions of the semantic parameters and L eq -D-IACC, two linear multivariate evaluation models of subjective spatial perception are proposed.
