Airport Noise Modelling


Global Coordinates is collaborating with to 70 to provide Airport Noise Modelling Training. To70 has wide operational and practical experience in airport noise modelling. This ranges from developing and validating aircraft noise modelling software, calculating noise exposure in various metrics and applying noise exposure-response relationships to predicting aviation impact on airport. Surroundings and identifying operational and non-operational measures, to alleviate the noise impact, and to presenting the results of noise assessments in an appealing and effective fashion.


Global aviation’s economic impact is estimated at 2.2 trillion US dollars, representing 3.5% of the worldwide Gross Domestic Product (GDP). The industry transports around 3 billion passengers every year and supports almost 57 million jobs. Within the Asia-Pacific region, aviation represents a 470 billion dollar industry, transports 780 million passengers and supports 24 million jobs. India represents a growing aviation market with 10 scheduled airlines operating nearly 400 aircraft with scheduled air services operational to/from more than 75 airports. In 2011, the country ranked ninth in the global civil aviation market, while five international airports have been built on public-private partnerships. In 2009, aviation represented 1.5% of India’s GDP (17.8 billion US dollars) and supported in total 8.8 million Indian jobs. During fiscal year 2011-2012, it transported approximately 100 million passengers. It is expected that domestic and international passenger traffic will continue to grow at rates of 12% and 8% respectively and that India will become the third largest aviation market in the world by 2020.

The growing aviation market significantly contributes to economic development, but inevitably also leads to environmental challenges, especially regarding noise. Noise represents one of the most significant environmental challenges associated with aircraft and airport operations across the world. The aviation industry has endorsed the balanced approach, which was introduced by ICAO in 2001 as the most appropriate method to address the aircraft noise challenge. The balanced approach is based on the consideration of four pillars: 1) reduction of noise at source; 2) land use planning and management; 3) noise abatement operational procedures; and 4) operating restrictions. Although there have been significant improvements based on the Balanced Approach, given the industry’s growth and the presence of population agglomerations near airports, large parts of population are still affected by aircraft noise across the world.

In India, the DGCA has already taken a number of important steps to address the noise challenge in line with the balanced approach, including setting up a regulatory framework, issuing noise-related circulars, establishing noise guidelines, and developing the first-ever noise study for Indira Gandhi International Airport in 2012.
