Characterizing Subjective Noisiness in Hospital Lobbies
The present study was conducted in the lobbies of 16 Taiwanese urban hospitals to establish what contributes to the degree of noisiness experienced by patients and those accompanying them. Noise level measurements were then conducted by 15 min equivalent sound pressure levels (LAeq, 15m, dB) during daytime hours. The average LAeq itself was found to be poorly related to perceived noisiness. Lev...
متن کاملTonal effects on perceived vowel duration
Cross-linguistically, there is a tendency for vowel duration to be inversely related to the approximate average f0; all else being equal, vowels on low tones are longer than those on high tones, while vowels on rising tones are longer than those on falling tones. This type of interplay between tonal contrasts and duration are commonly reflected in the world’s languages. This paper reports a stu...
متن کاملبررسی مقایسه ای عوامل مؤثر بر تعیین تراکم کروم شش ظرفیتی بعنوان یک سرطانزای شغلی
Introduction & Objective: Hexavalent chromium, Cr+6, is a very harmful pollutant and a relatively unstable compound that is present in many industries. It is a known human respiratory carcinogen and occupational exposure to this chemical is associated with different health hazards. The purpose of this study was to evaluate the effects of four parameters including: type of sampling head, sampl...
متن کاملTime on your hands: Perceived duration of sensory events is biased toward concurrent actions.
Perceptual systems must rapidly generate accurate representations of the world from sensory inputs that are corrupted by internal and external noise. We can typically obtain more veridical representations by integrating information from multiple channels, but this integration can lead to biases when inputs are, in fact, not from the same source. Although a considerable amount is known about how...
