Activity Report:

Sound, a normal feature of our life, is the means of communication and entertainment in most animals, including human beings. It is also a very effective alarm system. A low sound is pleasant whereas a loud sound is unpleasant and is commonly referred to as ‘noise’. Noise can be defined as an unpleasant and unwanted sound that is loud and disruptive to hearing. To address this sound issue, a guest lecture on "Noise Reduction and Control Drive" was organized by Department of Chemistry in collaboration with Department of Environmental Science delivered by the renowned expert Dr. Aruna Kakde. The program aimed to to the noise pollution that we experience daily, especially in our highly urbanised world today.This event was organised under star DBT project on 26/03/2025.
Context and Importance :-
Continuous noise refers to noise that is produced continuously by machinery that does not stop working while intermittent noise refers to the quick rise or drop in the noise volume. Additionally, impulsive noise is characterised by its sudden and fast nature. Low frequency noise refers to the background noise that we hear in our surroundings.
Noise pollution, an urban territorial phenomenon is assuming serious proportions in every city. The frequency and intensity of pollution has been increasing day by day. Noise pollution is an annoyance to human beings. The noise is usually machine-created sound that disrupts activity or balance of human’s way of life. Dr.Aruna Kakde has provided essential needs for educating both science faculties and students, raising awareness about this a growing environmental problem and discussing effective protocols.
Introduction to Noise Reduction
Dr.Aruna Kakde commenced the guest lecture by providing an in-depth introduction to Noise Reduction. She explained that Noise contamination is an undesirable or hostile sounds that irrationally interfere into our day by day exercises. It has numerous sources, the majority of which are related with urban improvement like street, air ,rail transport, modern noise , neighbourhood. The automobile repair shops, construction-works, blasting, bulldozing, stone crushing etc. are other sources of noise pollution.
She highlighted that external sounds can interfere with conversation and use of the telephone, and well as the enjoyment of radio and television programmes and like pastimes. It can thus affect the efficiency of offices, schools and other places where communication is of vital importance. The maximum accepted level of noise under such conditions in 55 dB. 70 dB is considered very noisy and serious interference with verbal communications is inevitable.
Doctors and scientist have now medically confirmed that noise disturbs the biological organisms and their respective functions of the humans. Fire crackers and other excessive and continuous explosives become physically painful giving rise to neurosis, mental illness, cardiovascular diseases, stomach ulcers and respiratory disorders reducing human life. Recent researches have concluded that short exposures to noise (in excess of about 100 dB) leads to adverse effects on foetus, headache and, dizziness, dilatoriness in intestines, stomach problems and effects on eye sights to the extent that these at times become incurable.
She elaborated further that Noise has little physical effect on the biological performance provided that the noise level is below about 90 dB. Damage to the inner ear may result if continuous noise levels exceed about 100 dB as has been observed by the Doctors leading to physical illness. The effect caused by industries, railways, crackers, explosions and commotion in the cities, aircrafts etc.can be felt on animals, birds, mice, fishes and domestic animals for they are susceptible to various effects of due to exposure noise levels change their places. Birds avoid migrating to places where noise level is above 100 dB. The noise emissions caused by supersonic aircraft, railway noise emissions etc., may cause miscarriage in mammals and fishes as well as birds are observed to have stopped laying eggs.
Preventive Measures /Control Drive:-
While discussing prevention, Dr. Aruna Kakde offered practical advice especially for the students and faculties attending the guest lecture. She emphasized that we can turn off home and office appliances when not in use such as TV, games, computers etc. it can create unnecessary stress on ears. We can save electricity also when we turn them off. We can shut the door after we turn on dishwashers or washing machines for rooms where it is kept or we can turn them on before leaving the house so that overlapping of exposure to loud noises can be reduced. We can listen to songs, radios, TVs in lower volume when listening from headphones or speakers. Stay away from Noisy area: Noise producing industries, airports, vehicles should be far from residential areas as it is very dangerous for infants and senior citizens.
Dr.Aruna Kakde concluded her session by advocating for increased public awareness on Noise Pollution. She proposed that we can notify government agencies if someone is not following rules and regulation regarding noise levels. Regularly checking noise level in an industrial complex and indoor to keep noise level within the limit. It is 24 necessary to control the noises created around us. It is necessary to aware people around us through various mediums. We can start from ourselves to spread awareness about noise pollution and its effects on human and the environment.
Contributions of Faculty Members
The success of the Guest Lecture would not have been possible without the contributions of the esteemed faculty members who facilitated the event. The Chairperson and Head of the Department of Chemistry, Dr.P.R.Mandlik, played a pivotal role in organizing and structuring the Guest Lecture,ensuring that the topics addressed were both timely and relevant. His opening remarks set the stage for an engaging discussion, underscoring the importance of addressing noise reduction and its prevention.
Chief Guest, Dr.S.P.Ingole, Head, Department of Environment Science.Her gracious presence and support ensured the event ran smoothly, and their interactions with the students helped foster a deeper understanding of the subject matter.
Professor Dr.K.J.Gawai, Depatment of Environment Science & Ms. R.D.Bankar, Asst.Professor ,Department of Chemistry were also key contributors for co-ordinating the event. Their commitment to student welfare and academic excellence was evident, as they guided the students through the complex topics discussed during the session. They actively participated in the interactive portions of the guest lecture posing insightful questions and helping the students clarify their doubts.



Chairperson's Remarks
The seminar concluded with closing remarks by the chairperson of the event Dr.P.R.Mandlik. Dr. Mandlik lauded the efforts of Dr.Aruna Kakde in delivering such an informative and critical session. He also expressed his appreciation for the Department of Environment Science for taking the initiative to organize the guest lecture.
Dr.P.R.Mandlik highlighted the importance of such academic engagements in bridging the gap between theoretical knowledge and real-world noise pollution challenges. He encouraged students to - Plant trees with no space or less space to reduce noise pollution. Evergreen shrubs that too with broader leaves provide year round noise protection so, they are best to plant. Trees absorb sound waves with their branches and foliage .
Overall the guest lecture on "Noise Reduction and Control Drive" was a resounding success, offering valuable insights into a critical sound effect on health . Dr.Aruna Kakde comprehensive presentation,causes and prevention of noie pollution equipped attendees with the knowledge needed to address this condition in clinical settings.The involvement of the faculties and the Chairperson of the event Dr.P.R.Mandlik. ensured that the event was not only informative but also inspirational, encouraging students and faculties alike to remain proactive in their approach to noise pollution.
Through this event, the Department of Chemistry and Department of Environment Science once again collaborated & its commitment to advancing noise pollution and addressing real-world noise control measures, paving the way for continued research and awareness in todays world.Outcomes of Guest Lecture :-
1. Noise pollution has numerous negative outcomes for human and animal health, impacting physical well-being, mental health, and even behavior.
2. Exposure to loud or prolonged noise can lead to hearing loss, stress, high blood pressure, sleep disturbances, and cognitive impairment, both in children and adults.
3. Additionally, noise pollution can disrupt wildlife behavior, affecting communication, hunting, and reproduction.
4. Repeated exposure to loud noise can damage the delicate hair cells in the inner ear, leading to temporary or permanent hearing loss.
5. Noise can trigger the release of stress hormones, leading to elevated blood pressure and potentially contributing to cardiovascular disease.
6. Noise can disrupt sleep patterns, leading to fatigue, irritability, and other health problems.
7. Noise can interfere with concentration, memory, and cognitive function, particularly in children.
