“…The Student Housing Survey was composed of six domains as follows: (i) demographic and other characteristics of the respondents; (ii) evaluating physical environment (Nisbet & Zelenski, 2014; Oppewal et al., 2017); (iii) evaluating hygiene and health services (Nazarpour & Norouzian‐Maleki, 2021; Thomas et al., 2018); (iv) evaluating safety and security (Brandon et al., 2008; Kıvanç, 2016); (v) evaluating social relations (Coon et al., 2016; Johnson et al., 2016; Wu et al., 2019); and (vi) evaluating equipment and installations (Caskey & Groll, 2018; Ryu & Song, 2019). Under the “physical environment” and “hygiene and health services” domains, eight and five items, respectively, were designed to assess the students’ overall residential satisfaction.…”

“…Recent studies shed light on the profound influence of architectural criteria of student housing on mental health (Moore et al., 2019); this has a tie‐in with overall satisfaction. The factors influencing residential satisfaction can be categorized into five areas as follows: (a) nature relatedness (Dean et al., 2018; Hurly & Walker, 2019); (b) hygiene and health services (Thomas et al., 2018); (c) controllability and security (Novianto, Gao, Kuroki, & Fukahori, 2016; Wang, He, Webster, & Zhang, 2019); (d) social relation (Boschman, 2018); and (e) equipment and installations (Caskey & Groll, 2018; Ryu & Song, 2019), although some scholars classified the latter category of variables as facility factors.…”

By living far away from the family, college students lose social support from their families, and therefore, they may feel loneliness, and lack of attachment to the new environment. The main objective of this study was to investigate the factors affecting residential satisfaction (RS) of students living in dormitories. A survey was developed and distributed to 850 students of the dormitory of Shahid Beheshti University in Tehran, Iran. After the data had been cleaned, the statistical analyses were conducted on 622 residents of the dormitory. Confirmatory factor analysis (CFA) and structural equation modeling (SEM) were utilized to capture the complex relationships among related constructs. The results revealed that the main factors that influenced RS were social relations and nature relatedness. The results confirmed the positive and significant effect of controllability and security on RS.

“…Fig. 2 shows pressure type and gravity type structure diagram [4] . Because the different water pressure and water temperature have a great impact on the noise of the pressure structure, in order to make an effective comparison, the water pressure in this test is (0.35 ± 0.05) MPa of static pressure and the water temperature is (15 ± 1)℃ [5] .…”

With the improvement of the living standards of urban and rural residents, the popularity of intelligent toilets is increasing year by year. The noise issue of intelligent toilets has become one of the main complaints from consumers. The noise of intelligent toilets mainly comes from three functions: cleaning, blowing, and flushing. Due to the lag in research on relevant noise measurement theories and technologies, there is currently a gap in the standards for supporting testing methods. This article adopts step-by-step measurement and overall measurement methods and selects F gear, S gear, and I gear to measure the noise of the tested samples separately. The measurement results of different methods are measured according to L50 and L10, providing a scientific basis for evaluating the noise-influencing factors of intelligent toilet products.

The article presents an analysis of noise in sanitary devices, and the described methods of reducing noise in places where noise occurs. The given results of noise tests of sanitary facilities and workplaces concerns one of the municipal company. Described sources of noise in water supply, sewage as well as ventilation and air conditioning systems. It has been shown that the noises occurring in residential buildings may be caused by excessively high pressure inside the installation, where, for example, when closing the valve, a water hammer phenomenon arises, causing audible noises, especially when the installation is made of metal materials. The article analyzes noise in sanitary facilities, describes the methods of reducing noise in places where noise occurs. The given results of noise tests of sanitary facilities and workplaces in one of the municipal companies of the city of the Subcarpathian province. Described sources of noise in water supply, sewage as well as ventilation and air conditioning systems. It has been shown that the noises occurring in residential buildings may be caused by excessively high pressure inside the installation, where, for example, when closing the valve, a water hammer phenomenon arises, causing audible noises, especially when the installation is made of metal materials. It has been shown that the main causes of noise in plumbing systems can be rigid pipe fittings. Noises in the sewage system are related to the outflow of used water in vertical and horizontal sections. The phenomenon most often occurs in places connecting vertical pipes with horizontal pipes, as well as the use of too small diameters of pipes. Material noise reduction in sewage systems can be ensured thanks to a properly designed system of fastening pipes to fixed elements. An important step is to use appropriate sound insulation to stop unwanted sounds. The reason for noise in the air-conditioning and ventilation system are changes in the velocity of the flowing air mass and the occurrence of turbulences during the change of the air flow direction. This causes the ducts to resonate and the air flow noise through the diffusers. The most common noise problem in the central heating installation is the use of a solid fuel boiler, the maintenance work of the device is a problem, as it requires cleaning the furnace, which is related to the noise that is transmitted through the installation pipes to the rooms. Based on the analysis of workstations at the municipal company plant, it has been shown that the highest conformity deviation level is in the drying room in the position of a machine and device operator
