Analysis of noise pollution level in a University campus in South India

Abstract

Abstract. Noise comprises those sounds occurring around us that are not part of the environment under consideration. Noise is also a type of pollution and impacts on our health and wellness. The prevalence of noise is increasing in magnitude and severity because of growing population and urbanization. Noise pollution leads to many chronic and socially significant impacts. This study analyzes the level of noise at different points in SRM University. As the University encompasses a hospital also, it is more important to identify the sources of high noise levels and control them. As per Indian standards the desirable noise pollution for educational institutions and hospitals in daytime is 50 dbA. Noise levels were measured with a sound level meter at 19 points within the campus at three different timings (8-10 am, 12-2 pm, and 3-5 pm) over two cycles of measurements. The preliminary results show higher noise levels during morning and evening. Noise during Cycle 2 (latter half of semester) was 20% more compared to that of Cycle 1 (beginning of semester).

Redefinition of Park Design Criteria as a Result of Analysis of Well-Being and Soundscape: The Case Study of the Kortowo Park (Poland)

“…According to analyses carried out during the soundwalk interviews in the park, users perceived the park's area as the least friendly, loud, and annoying in parts which usually border the main road. Similar results were obtained in academic campuses in Turkey [82], India [83], or Brazil [87].…”

“…In addition to acoustic valor of greenery in university campuses that is marked in our research, it should be considered as one element in a more complex environmental system, where soundscape together with water management [ 73 ], energy consumption [ 74 ], or climate mitigation actions [ 75 ] can create academic campuses as sustainable educations hubs influencing the surrounding and promoting a built environment of 21st century. Such actions in redesigning academic campuses according to modern urbanization concepts can be observed in many countries around the globe like France [ 76 ], Spain [ 77 ], Italy [ 78 ], Poland [ 79 ], Germany [ 70 ], Finland [ 80 ], US [ 81 ], Turkey [ 82 ], India [ 83 ], China [ 84 ], Singapore [ 85 ], Malaysia [ 86 ], or Brazil [ 87 ].…”

Analysis of Noise Level and Sound Transmission Loss (STL) of Noise Barrier Material for the Construction Site

“…The noise data is measured in two daytime sessions; one in the morning (9AM-12PM) and another one in the noon session (2PM-5PM) for two semesters of study period [22]. Each semester runs from November to December 2018 and from February to March 2019 [23]. The sound level meter is used as the noise level measuring tool at three measurement points of M1, M2 and M3 as shown in Fig.…”

Investigation of Noise Pollution in an Educational Building – Case Study of Babylon University in Iraq

“…It is observed that indoor acoustic quality is a critical indicator for architects and engineers during the design and renovation of structures [2]. Indoor acoustic quality enables us to evaluate a building's energy efficiency by analyzing its energy usage in relation to the indoor environment quality that can be achieved indoors [3]. Educational areas are those in which much time is spent reading, writing, examining maps, or focusing attention on monitors.…”
