Aircraft Noise: Aircraft noise pollution has become a major concern in the past decades. In order to combat this, a congress pass a law requiring airports to keep aircraft below 75 decibels in residential areas. However, it’s been found that these laws aren’t enough since they are mainly enforce on the weekends and not during the week when aircraft are most likely to be flying at an even higher decibel rate.
Introduction
The airplane industry is responsible for producing some of the most notorious noise pollution in the world. Aircraft engines produce a wide variety of noises. Including high pitch tones, droning sounds, and thumping vibrations. These sounds can be extremely disruptive to people living nearby, and they are also harmful to the environment.
Aircraft pollution can cause physiological problems such as sleep deprivation and stress. As well as environmental damage such as loss of vegetation and wildlife populations. There are a number of ways that aircraft manufacturers can reduce or eliminate their production of noise pollution. They can adjust their engines or designs to produce less sound, or they can work to find alternatives to traditional aircraft technologies.
Basics of Aircraft Noise Pollution
There are many different aircraft pollution sources, and each has a unique source location and noise production characteristics. Aircraft noise pollution can come from various types of aircraft: commercial. Military, general aviation, and helicopters. Commercial aircraft are the largest source of aircraft pollution in the Unit States. Commercial aircraft produce high pitch noises known as “jet noises” that can be heard up to 20 miles away from an airport.
Jet noises come from the engines. Propellers, and airframe vibrations. Military aircraft produce lower pitch noises commonly refer to as “whistles” or “buzzes.” These noises are often louder than jet noises and can be heard up to 5 miles away from an airport. General aviation aircraft produce loud “thumps” or “rumble” sounds that can be heard up to 3 miles away from an airport. Helicopters produce high pitch screeches that can be heard up to 10 miles away from an airport.
Noise levels vary greatly depending on the time of day and weather conditions. During daylight hours, noise levels tend to be lower than at night or in bad weather conditions because fewer people are around to hear the noise. Aircraft also fly less frequently during daylight hours because there is less demand for air travel. Noise levels also increase during wartime when more flights are necessary to transport troops and supplies to combat areas. Aircraft manufacturers have develop several technologies aim at reducing the level of aircraft noise pollution produce by their
How does aircraft noise pollution affect people?
Scientific evidence has long shown that aircraft noise pollution can cause serious health problems for people living near airports. Studies have consistently shown that exposure to can increase the risk of developing a number of chronic health conditions. Including high blood pressure, sleep disorder, and stress. In addition, research has also demonstrate a link between and increase rates of cardiovascular disease and stroke.
Given the clear links between aircraft noise pollution and negative health outcomes. It is no surprise that regulators around the world are taking action to reduce the level of noise pollution from aviation. In the Unit States, for example, Congress pass the Air Quality Improvement Act in 1990 mandating that federal agencies set stringent air quality standards for all categories of aircraft emissions. The Federal Aviation Administration (FAA) has since update these regulations several times to ensure that they are as protective as possible of human health.
In Europe, where aviation is a far more significant source of air pollution than in the Unit States. Governments have taken even more proactive measures to protect citizens from airborne noise. The European Union has establish strict limits on how much noise each type of aircraft can produce, and member states have been require to enforce these regulations since 1999. This system has had a dramatic impact on aviation industry emissions levels in 2005, for example, EU aviation sector emissions were only 8% of their 1990 levels and it has help to improve public health across Europe overall.
What are the causes of aircraft noise pollution?
Aircraft noise pollution is a problem that has been steadily growing in recent years. The main cause of aircraft noise pollution is the increase number of air travel episodes. Aircraft engines produce a loud noise that can be heard from great distances away. This noise is particularly troublesome for people living near airports because it can interfere with their quality of life. There are several other factors that contribute to aircraft noise pollution. These include the use of older, louder engines. The fact that more planes are taking off and landing simultaneously, and the lack of progress made in reducing aircraft emissions. It is important to remember that there is no one solution that will solve all of the problems associate with aircraft noise pollution. Rather, different measures must be put in place to address each source of this nuisance.
Conclusion
Aircraft noise pollution is a growing global problem, and it’s one that we need to address before it becomes even worse. Aircraft noise can cause significant
