Abstract
Uncontrolled growth in urban traffic has led to the deterioration of environmental quality in terms of pollution. The purpose of this study was to predict the noise levels of Alagappa College of Technology (AC TECH) and the School of Architecture and Planning (SAP) in terms of traffic volume, vehicle speed, and road geometry definition, and to compare predicted noise levels with visual value and recommended appropriate noise reduction measures. Sound levels were recorded at 15 locations at Alagappa College of Technology and the School of Architecture and Planning. The highest noise levels in the class were 74.05 dB (A) and 72.91 dB (A). The highest noise levels in the hall were 72.71 dB (A) and 71.5 dB (A). The highest noise levels in the library were 63.54 dB (A) and 62.76 dB (A), not the permissible noise levels of 35-40 dB (A) in the hall and classrooms, and 40-45 dB (A) libraries depending on -IS 4954 (1968). In addition, the noise levels are also not within the permissible noise levels according to the Indian Ambient Noise Standards (CPCB 2000).
