28-OCT-2017: Dept of Mechanical Engineering starts 46th National Symposium on Acoustics
Aligarh, October 28: The Department of Mechanical Engineering, Zakir Hussain College of Engineering and Technology (ZHCET), Aligarh Muslim University (AMU) today started the 46th National Symposium on Acoustics at the Polytechnic Auditorium. The three-day programme will have experts from across the country, discussing important research activities for curbing noise pollution.
During the inaugural function, AMU Vice Chancellor, Professor Tariq Mansoor who is also the chief-patron the symposium pointed out that since noise pollution is reaching alarming levels; many cities across the world have started silent airports where emphasis is made to suppress noise from wheels, wings and the fuselage during takeoff and landing.
Professor Mansoor added that we need to reduce noise pollution from the road and rail traffic and also unwanted noise from industries and neighbourhoods as it is affecting human health and well-being in a number of ways.
The chief-guest, Dr D K Aswal (Director, Council of Scientific & Industrial Research-NPL) said that people are suffering annoyance reactions, sleep disturbances, and interferences with communication because of the everyday noise pollution. He added that unnecessary noise is leading to hearing loss and behavioural changes.
Dr Aswal further said that in order to reduce noise pollution, we need to reduce noise at its source in industries and automobiles. ?Try not to put the TV on hi-fi speakers; plant trees at roadsides, put curtains and glass panes on the doors and windows to interrupt the path of the noise; do not unnecessarily blow horns and if the source of noise is unavoidable cover your ears by hands or use ear plugs,? said Dr Aswal.
Delivering the presidential address, Dr V R Singh (President, Acoustical Society of India?ASI ) said that the unit of sound intensity above 120 decibels is noise and anything over 130 decibels is the upper limit of the threshold of hearing which will lead to hearing impairment.
Prof Mohammad Idrees (Dean, Faculty of Engineering and Technology) said that the Acoustical Society of India was established to increase and diffuse the knowledge of acoustics and promote its practical application at Visakhapatnam.
Prof M M Sufiyan Beg (Principal, Zakir Hussain College of engineering and Technology, AMU) pointed out that the western countries of Europe and the Pan America do not even allow excessive use of horns on roads and we need to take appropriate measures in India too.
Prof Mohammad Altamush Siddiqui (Chairperson, Department of Mechanical Engineering) said that public awareness about noise control can play an important role to reduce it. He added that with time, the consequences of noise pollution will become even more worrying.
Mr Mahavir Singh (General Secretary, ASI) said that this symposium will bring scientists and academics together to create awareness about the impact of noise pollution. He also announced NSA and ASI Awards, which were presented by Dr V K Singh.
Prof Ahmad Ali Khan (Convenor of the symposium) delivered the welcome address, while Dr Yasser Rafat (Organising secretary of the symposium) proposed the vote of thanks.
