In this study, urban soundscapes containing combined noise sources were evaluated through field surveys and laboratory experiments. The effect of water sounds on masking noises was then examined in order to enhance the soundscape perception. Field 16 spaces conducted soundwalking evaluate annoyance sources. Synthesis curves derived for relationships between levels percentage highly annoyed (%HA) (%A) Qualitative analysis also made using semantic scales evaluating quality soundscape, it shown...
The aim of this study is to investigate the effect audio-visual components on environmental quality improve soundscape. Natural sounds with road traffic noise and visual in urban streets were evaluated through laboratory experiments. Waterfall stream water sounds, as well bird selected enhance Sixteen photomontages a streetscape constructed combination two types features three vegetation which chosen positive components. experiments consisted audio-only, visual-only, conditions. preferences...
The goal of the present study is to characterize water sounds that can be used in urban open spaces mask road traffic noise. Sounds and visual images a number features located places were obtained subsequently analyzed terms psychoacoustical metrics acoustical measures. Laboratory experiments then conducted investigate which sound appropriate for masking consisted two sessions: (1) Audio-only condition (2) combined audio-visual condition. Subjective responses stimuli rated through use...
This study proposes a soundwalk procedure for evaluating urban soundscapes. Previous studies, which adopted methodologies investigating participants' responses to visual and acoustic environments, were analyzed considering type, evaluation position, measurement, subjective assessment. An individual was then developed based on asking subjects walk select positions where they perceived any positive or negative characteristics of the soundscape. A case performed in spaces results compared with...
The aim of this study is to characterize urban spaces, which combine landscape, acoustics, and lighting, investigate people’s perceptions soundscapes through quantitative qualitative analyses. A general questionnaire survey soundwalk were performed soundscape perception in spaces. Non-auditory factors (visual image, day olfactory perceptions), as well acoustic comfort, selected the main contexts that affect perception, context preferences overall impressions evaluated using an 11-point...
This study uses a structural equation model to examine the effects of noise on self-rated job satisfaction and health in open-plan offices. A total 334 employees from six offices China Korea completed questionnaire survey. The included questions assessing disturbances speech privacy, as well health. results indicated that disturbance affected Contrary popular expectation, relationship between was not significant. Rather, with environment were negatively correlated lack privacy. Speech...
Illuminance levels have been standardized and regulated for many purposes. However, the effects of correlated colour temperature lighting received little attention in field. This study investigated on brightness sensation, perception, cognitive performance 60 students under ambient light emitting diodes (LED) conditions (CCT: 3000 K, 4000 5700 K; illuminance: 650 lx 1050 lx) an actual university classroom. An increase (CCT) led to sensation. increased CCT did not linearly comfort. A K was...
This paper presents the outcomes of "Soundscape Attributes Translation Project" (SATP), an international initiative addressing critical research gap in soundscape descriptors translations for cross-cultural studies. Focusing on eighteen languages – namely: Arabic, Chinese, Croatian, Dutch, English, French, German, Greek, Indonesian, Italian, Japanese, Korean, Malay, Portuguese, Spanish, Swedish, Turkish, and Vietnamese study employs a four-step procedure to evaluate reliability validity...
The acoustic characteristics of various kinds water sounds were investigated to evaluate their suitability for improving the soundscape with road traffic in urban spaces. Audio recordings made spaces features such as fountains, streams, sculptures, or waterfalls. temporal and spectral aspects clarified, subjective evaluations performed find proper level difference between noise making more subjectively pleasant. results indicated that perceptual sound was around 3 dB noises from background....
