Noise Pollution Levels by Aircraft Types

Airports are now a part of our lives. We often use airports for business, sometimes vacation or for other reasons. On the other hand, airports located close to residential areas can sometimes be annoying due to noise pollution. Aircraft noise has been the subject of many researches for years due to the pollution of the noise it gives to the environment. However, there are gratifying results on this subject in an analysis made by Eurocontrol. Let’s take a look together.

Over the years, advances in both engine technologies and aircraft aerodynamics have brought about a serious decrease in noise levels.

Aircraft Noise Pollution

In a chart prepared by Eurocontrol, it is possible to clearly see the decrease in the noise level of aircraft engines.

The results in the graph are prepared according to the Effective perceived noise in decibels (EPNdB) unit of measure.

According to this, the noise level of aircraft such as the Boeing 727 and Boeing 747-200, which are now few in the skies, is above 100 decibels.

The noise level of Airbus A320 and Boeing 737-800 type aircraft, which are widely used in the medium category all over the world, is around 93-94 decibels.

The noise level has decreased to around 90 decibels in Airbus A350, Boeing 787, Airbus A320neo and Boeing 737 MAX aircraft, which are the most modern passenger aircraft today.

In fact, the noise level fell below 90 decibels on the A320neo.

As the number of new generation aircraft increases over time, it seems that the noise pollution to which the inhabitants of the airport’s landing-take-off routes will relatively decrease.
