“…It can be expressed and explained by the one‐vote veto tendency effect of individual factor perceptions on the overall satisfaction, that is, the effect wherein occupants will aggravate their dissatisfied emotion with the overall environment if an individual environmental factor is far away from their expectations or sensations. Few studies considered such effect 56 and it was verified and explained in our previous research 42 . Such one‐vote veto tendency effect of individual factor perceptions on the overall satisfaction was expressed and indicated by the conditional probability of dissatisfied with the overall environment given different combinations of environmental satisfaction (Eq.…”

“…As for the probability of OS = −1 given that O t has happened (i.e., P (OS = −1 |O t )), it has also been proposed and determined in our previous research 42 . The proportions of subjects that were dissatisfied with the overall environment under eight combinations of individual factor satisfaction levels were also described as conditional probabilities as follows:

P false(OS = ‐ 1 false| O_{t} false) = \{\begin{matrix} 1, t = 1 \\ 0.9889, t = 2 \\ 0.9091, t = 3 \\ 0.7727, t = 4 \\ 0.9859, t = 5 \\ 0.8213, t = 6 \\ 0.6571, t = 7 \\ 0.0358, t = 8 \end{matrix}

Previous studies have developed plenty of mathematical models for assessing indoor environment quality. Literature reviews that most of them presented a mean value of perception of a population and ignored the interaction effects of multiple environmental factors on occupants’ perceptions. In this regard, the aim of our paper is to develop a comprehensive indoor physical environment quality (IPEQ) index which could present a whole picture of perception of a population by taking the combined effects (i.e., main, crossed and interaction effects) into consideration. The hypothesis and methodology of quantitation were firstly proposed according to Probability Theory. Our quantitation was performed based on the subjective perception votes that collected from 216 experimental conditions in a controlled laboratory. Three 3‐input 7‐output Artificial Neural Network models were subsequently developed for predicting probability mass functions (PMFs) of 7‐point sensation votes under the combined effects of temperature, illuminance, and sound level. Thereafter, the PMFs of 3‐point satisfaction votes were expressed and calculated by using Law of Total Probability. Finally, a comprehensive IPEQ index‐Predicted Probability Overall Dissatisfied (PPOD) index, which provides an estimate of how many occupants in a space would feel dissatisfied with the overall physical environment, was developed. The predicted expected value of overall satisfaction distribution (average overall satisfaction) was validated to be roughly in accordance with previous studies and more reasonable when at least one kind of environmental factor was far away from expectation. The new quantitative measure also indicated that the minimum PPOD is 17.55% (air temperature = 24.3°C, illuminance = 910Lx, sound level = 35 dB) within common ranges of environmental parameters. It was also discussed that our new quantitative measure could provide quick and direct suggestions for controlling or designing the indoor environment.

“…So, we can see a certain inconsistency here, which could be caused by the predominance of visual assessment over auditory perception. Researchers are not consistent in opinions when it comes to the major factor influencing the final perception of the well-being of users, considering the role of acoustic and visual factors [ 95 , 96 , 97 ]. Moreover, they include also thermal conditions as a driver influencing final evaluation [ 95 , 96 , 98 , 99 , 100 ].…”

Well-being and soundscape analysis should be useful in re-design works involved in the planning of recreational areas and green spaces on campuses to improve the health of students, academics, and university staff. Proper space planning, for example, in campus parks, including the planning of soundscape zones, is important in relieving study and work stress. The aim of the study was to conduct a multicriteria analysis of the soundscape and well-being of users in the university park on campus in Olsztyn (Poland). It was important to redefine thinking about the re-composition of park space, including reduction of noise and improving well-being. The research included: 1. measurements of sound pressure levels (SPL) at selected points in two periods, 2. interview with park users and preparation of a mental map, 3. experts’ opinion on soundscape and well-being, and 4. design schemes for re-design of the park. The results of research regarding the perception of the soundscape and well-being in Kortowo park by respondents differ slightly from the results of SPL measurements. The results also confirm the difference between SPL in the leafless and leafy period. The results show a clear relationship between the perception of sounds and well-being in the park. However, in some areas near the water, where higher noise levels are reported the respondents felt quite comfortable. Finally, design schemes are proposed, based on experts’ opinions and results of the analysis.
