We are pleased to announce that IISA2025 will feature TEN Distinguished Plenary Speakers. Further details about their lectures will be shared as they become available.
#1 Propagation and Mitigation Model of Mixed Road Traffic Noise for Kanpur
Prof. Manoranjan Parida, Department of Civil Engineering, Indian Institute of Technology, Roorkee has taken over charge of Director, CSIR-Central Road Research Institute on 20th September, 2022.
Prof. Manoranjan Parida was Deputy Director at IIT Roorkee before joining CSIR-CRRI. He has been MoRTH Chair Professor on Development of Highway System in India at IIT Roorkee during 2013-2017. He has worked on an Imprint Research Project “Propagation and Mitigation Model of Mixed Traffic Noise for Planning Mid-Sized Indian Cities”. Design and Development of Noise Barrier for Flyovers in Delhi is an innovative contribution by him. He has provided substantial inputs for third party quality audit of 1700 km. of State Highway in the State of Bihar (during 2007-2013) under the RSVY Project. He has provided consultancy for more than 350 urban road infrastructure projects, intercity corridors, rural roads, and expressways. He received Pt. Jawaharlal Nehru Birth Centenary Award in the year 2004 from Indian Road Congress. He has received the Outstanding Teacher Award of IIT Roorkee. He is presently Convener of Traffic Engineering & Transportation Planning (H-1) of Indian Roads Congress, New Delhi and Convener of Bitumen, Tar & Other Products (PCD 6) Committee of Bureau of Indian Standards. Currently Prof. Parida is President of Indian Roads Congress.
Director, CSIR-Central Road Research Institute, New Delhi, India.
My lecture shall explain development of a scientifically robust model to assess and mitigate mixed road traffic noise for Kanpur City taken up under IMPRINT Project. The primary outcome of this research has been a traffic noise propagation and mitigation model suitable for Indian mid-sized cities, where road traffic is typically mixed and complex. The research involved extensive field data collection across residential, commercial, industrial, and silence zones of the City and a detailed classified volume and speed analysis across different vehicle types, including electric vehicles. Traffic Noise Modelling was taken up through REMEL (Reference Energy Mean Emission Level) equations for 11 vehicle categories and FHWA-based models to estimate equivalent noise levels (Leq) with high accuracy. Noise Mitigation aspect were studies through attenuation effects of vegetation, distance, and physical barriers like boundary walls.

#2 Community-based approaches to creating sound-based place identity
Christina Mediastika is a tenure-track Professor of Architecture at the School of Creative Industry, Universitas Ciputra Surabaya, Indonesia. She holds a doctoral degree from the University of Strathclyde. Her primary area of expertise is architecture, focusing on architectural and environmental acoustics. She developed an interest in this field due to the community's low awareness and limited knowledge regarding the importance of sound in daily life. Often undervalued in architecture, sound is an element that Christina strives to incorporate into her students' design projects from the outset. Her understanding of sound's significance in our environment deepened when she began working with visually impaired communities in 2017. Through this experience, she learned that an ideal sound environment consists of background and distinctive sounds. This awareness is essential for the visually impaired and benefits everyone, as human ears are more sensitive than our eyes when perceiving surroundings. This means they let both positive and negative surrounding conditions into our body more readily than the eyes, which can be closed for unwanted visuals. Unfortunately, this sensitivity is not usually utilised or trained as much as our visual senses. In addition to her work with visually impaired individuals, Christina has recently initiated a research series aimed at preserving and, where necessary, restoring the unique historical sounds of Indonesian cities. She sees these sounds as treasures of the country's intangible heritage and a crucial part of urban identity, which modern lifestyles have significantly taken over. Christina and her team's works have been published in reputable journals, conference proceedings, and books.

Sound is often an undervalued aspect of life, especially in developing countries, where low awareness about its significance stems from more pressing concerns like food security and financial stability. A review of noise profiles and law enforcement in developing nations within the ASEAN region highlights this issue, supported by the value of society over the self. In such contexts, the noise generated by communities is often not viewed as problematic. Acoustic environments in these countries are dominated by traffic noise, lacking distinctive sounds that help establish a place’s identity, which is particularly important for visually impaired individuals in countries like India and Indonesia, which have the highest blind populations globally, according to the UNDP in 2017. Unique sounds are vital for blind individuals as they help navigate and identify potential dangers. Before modern machinery and lifestyles, each location had distinctive sounds, often from daily life, cultural practices, and transportation. These sounds helped distinguish one place from another. However, preserving these distinctive sounds has become increasingly complex with the shift to modern living forms. A feasible approach to preserving these sounds is through virtual preservation before they are lost with the passing of source persons who experienced them. This effort involves qualitative and quantitative methods, with local communities, including blind people, playing a key role in data collection. Given the subjective nature of sound perceptions, researchers must consider diverse factors and recommendations to translate their findings into virtual and real-world settings effectively.
