In an effort to make the surrounding residential area in south-west London quieter, the airport authority will rank the 80 airlines that uses the facility according to how noisy their aircrafts are.
Fines for carriers that break maximum noise levels, which differ according to the time of day, range from 500 to 1000 pounds (USD 1,500) per violation. Fewer decibels are allowed during the night.
"Heathrow is at the forefront of international efforts to tackle aircraft noise and, as a result, even though the number of flights has almost doubled since the 1970s, fewer people are affected by noise," said Heathrow chief executive Colin Matthews.
Colin believes the noise levels will also go down as a new generation of quieter, more fuel efficient jets such as Boeing's 787, are used by more carriers.

The program, partially funded by Heathrow authority includes 'adobe building' for local schools, which involves the construction of igloo-like shelters made from bags of earth and plaster to allow pupils to study outside without being disturbed by aircrafts.
