“…30 However, if windows and doors on the corridor side are open to allow for cross-ventilation, pollution can spread among classrooms on the same floor through corridor 31,32 and increase noise levels. [32][33][34][35][36] To find out the real situation in the classroom, a typical corridor-style classroom was monitored. The classroom had four openings on one side and a corridor on the other side.…”

Natural ventilation can cool down the indoor environment and improve the air quality of buildings without consuming energy. The configuration of an inner corridor with double-sided classrooms is widely used in school buildings because of advantages such as space-saving and compactness. However, the inner doors or windows on the corridor side of these classrooms are often closed due to the dispersion of pollution and noise between classrooms. To introduce more fresh air from the outside, this study proposes a novel design to set up a horizontal airflow channel through the building to provide cross-ventilation for classrooms on both sides. A computational fluid dynamics (CFD) model was verified using experimental data and was employed to predict the airflow rate of the air channel by investigating different, sizes of air channels, wind directions, wind velocities and climate data, to assess the potential of the technology. The implementation of a channel area-to-floor area ratio of 2% (1.8 m2) provided an average increase in the ventilation rate of 215% on an annualized basis when applied and simulated in typical conditions from 10 different cities in China. This technology could be used to improve natural airflow rates in other buildings which use interior corridors in their design.

“…It has been estimated that the prevalence of voice disorders in teachers is two- to three-fold higher than the prevalence in the general population [ 1 ]. Risk factors for voice disorders in teachers include environmental conditions (acoustics, noise, humidity, dust and temperature), organizational characteristics (long work hours, excessive number of students per classroom, multiple jobs and excessive voice demand), biological factors (allergies, reflux and infections of the upper respiratory tract), and psychological disorders (depression and anxiety) [ 1 – 6 ].…”

This study aimed to examine the association between voice disorder and depressive symptoms in schoolteachers. A cross-sectional survey was conducted with elementary and secondary schoolteachers. Voice disorders and depressive symptoms were assessed with the Voice Handicap Index-10 and the Beck Depression Inventory-II, respectively. Logistic and linear regressions models were adjusted for confounding variables. In the 389 schoolteachers studied, the prevalence of voice handicap and depressive symptoms was 18.8 and 38.8%, respectively. Voice handicap was associated with depressive symptoms on all models tested. The logistic regression showed an odds ratio of 2.21 (95% confidence interval: 1.19, 4.08; p value < 0.05), while in the linear regression each point increase on the voice disorder scale increased the Beck Depression Inventory-II score by 0.39 points (95% confidence interval: 0.26, 0.54; p value < 0.05). This study showed that teachers of public schools with voice handicap are twice as likely to report depressive symptoms.

“…Noise pollution is a major environmental hazard that not only affects our daily work and life, but also poses a danger to our health [1]. Numerous studies [2][3][4] have shown that noise not only directly causes hearing loss, but also increases annoyance and insomnia [5,6], increases the risk of arteriosclerosis and coronary heart disease [7][8][9], and negatively impacts mental health [10]. Noisy conditions on university campuses have direct negative effects on students' learning and also on the teaching environment of many teachers [11,12].…”

Application of University Campus Noise Map Based on Noise Propagation Model: A Case in Guangxi University

Considering the characteristics of a campus environment and the rules that govern outdoor sound propagation, this paper identifies traffic noise as the dominant noise source of the campus environment based on the measurement of the noise environment. A noise propagation model that is suitable for university campuses was developed and used it was to create a noise map of the ambient area of the teaching building on the campus of Guangxi University. This noise map was then utilized to analyze the noise environment. The results revealed that for a given teaching building, the noise disturbance on high-rise classrooms is more significant compared to the impact on low-rise classrooms. Attention should then be paid to noise control in the high-rise classroom of the building. By appropriately increasing the distance between the building and the main traffic road or by adopting a judicious soundscape design that considers the shape of the building, it is possible to effectively reduce the interference of noise during teaching activities in a building and improve the sound quality of the campus environment. The results of this study provide a theoretical framework for the governance of the campus acoustic environment.
