“…In the Increasing and Decreasing Sound conditions, the visual displays were paired with an auditory stimulus that conveyed the impression of a sound source that, respectively, was either approaching the participant or receding towards the background. The impression of the sound source moving was obtained by modulating the intensity of the sound: intensity is described as the feature that better accounts for the motion of a sound source in space (Canzoneri et al, 2012;Maier & Ghazanfar, 2007;Middlebrooks & Green, 1991;Neuhoff, 1998;Rosenblum et al, 1987;Seifritz et al, 2002;Wilkie & Stockman, 2020). The auditory stimuli were two samples of a sinusoidal waveform of 4000 ms duration with constant frequency (8000 Hz) and presenting a variation in intensity of 15 dB SPL, from 55 to 70 dB and vice versa.…”

“…Previous studies used ecological stimuli, such as moving trains, cars, faces and toys: it is possible that the choice of the stimuli and their different salience could have had an impact on the different patterns of responses that have been observed. In the present study, instead, we decided to present the infants with visual and auditory stimuli that were salient yet unlikely to have been experienced by the infants in their everyday lives: this allowed us to investigate infants' matching of crossmodal stimuli irrespective of their specific experience of those stimuli (Maier et al, 2004;Wilkie & Stockman, 2020).…”

Perceiving motion in depth is important in everyday life, especially motion in relation to the body. Visual and auditory cues inform us about motion in space when presented in isolation from each other, but the most comprehensive information is obtained through the combination of both such cues. We traced the development of infants’ ability to discriminate between visual motion trajectories across peripersonal space and to match these with auditory cues specifying the same peripersonal motion. We measured 5-month-old (n=20) and 9-month-old (n=20) infants’ visual preferences for visual motion towards or away from their body (presented simultaneously and side-by-side) across three conditions: i) visual displays presented alone, ii) paired with a sound increasing in intensity, iii) paired with a sound decreasing in intensity. Both groups preferred approaching motion in the visual only condition. When the visual displays were paired with a sound increasing in intensity neither group showed a visual preference. When a sound decreasing in intensity was played, instead, the 5-month-olds preferred the receding (spatiotemporally congruent) visual stimulus, while the 9-month-olds preferred the approaching (spatiotemporally incongruent) visual stimulus. We speculate that in the approaching sound condition the behavioural salience of the sound could have led infants to focus on the auditory information alone, to prepare a motor response, and to neglect the visual stimuli. In the receding sound condition, instead, the difference in response patterns in the two groups may have been driven by infants’ emerging motor abilities and their developing predictive processing mechanisms supporting and influencing each other.

“…Pengukuran intensitas bunyi di aliran sungai Cinangneng-Bogor telah berhasil dilakukan. Sesuai dengan konsep dasar ilmu Fisika, bahwa nilai dari intensitas bunyi besarnya berbanding terbalik dengan kuadrat jarak (Wilkie et al, 2020). Semakin jauh dari sumber kebisingan, maka semakin rendah tingkat kebisingannya seperti ditunjukkan pada Tabel 1.…”

Noise pollution can come from noise generated by nature, one of which is noise from river flows. Therefore, the aim of this research was to determine whether the sound intensity level of the river flow is still below the threshold value or whether it has disturbed human hearing. The research method used was to measure the sound intensity level of the Cinangneng-Bogor river flow by using a sound level meter application. Measurement of the sound intensity level was carried out at 5 measurement points, namely in the middle of the river flow, on the river bank, at a distance of 5 m, 10 m and 15 m from the river bank to the land. Each measurement was carried out for 120 seconds. The results showed that the sound intensity level of the Cinangneng-Bogor river flow at several measurement points had different values, namely from the middle of the river to away from the river the values were 96.34 DbA, 92.31 DbA, 78.93 DbA, 76.58 DbA and 76.32 DbA. In conclusion, the further away from the noise source, the lower the noise level. The sound intensity in the middle and on the river bank was above the threshold value.
