Noise standards and the impact of noise on teaching and learning activities

Abstract

This study investigates noise pollution, a significant environmental and public health concern. It provides a comprehensive overview of noise standards in Vietnam, the United States, and Japan, comparing permissible levels across various environments including specific areas, residential zones, and workplaces. The comparative analysis reveals substantial variations, with Japan imposing the strictest regulations, particularly noted in special areas and workplaces. The document then examines the far-reaching impacts of noise, detailing its effects on general health, including nervous system, cardiovascular issues, sleep disorders, and hearing loss. Crucially, it explores the specific impacts on teaching and learning activities, highlighting impairments to cognitive performance, creation of communication barriers, and adverse health effects on both students and lecturers. A practical measurements study was conducted by students under supervisor of lecturer, at Lecture Hall A2, in University of Transport and Communications. Actual noises levels were collected by students during class and break times, and these measurements frequently exceeded both Vietnamese and United States standards, particularly when influenced by external sources like the metro and traffic. Based on these findings, the research proposes a range of technical and management solutions aimed at mitigating noise pollution in educational settings, such as installing soundproof materials and adjusting operational schedules.
