Isn t it noisy to fly? Loud noise? No soundproofing?

Noise levels when flying can vary depending on a number of factors. Here are some of the possible causes of aircraft noise:

1.Aircraft type: Different aircraft types may have different noise levels. For example, an older aircraft may be noisier than a newer aircraft.

2.Engine type: The type of engine in an aircraft can also affect noise levels. Some engine types can be noisier than others, especially during take-off and landing.

4.Flight altitude: When the aircraft is flying at a higher altitude, noise may be reduced due to the thin air.

6.Airport location: Airports located in city centers or residential areas may be closer to people, so noise may be more noticeable.

While aircraft noise can be noisy in some cases, most modern aircraft are equipped with advanced soundproofing technology, such as thickened windows and soundproofing materials, to reduce the impact of noise. In addition, passengers can also choose to sit in a quieter location, such as at the rear of the cabin or above the wings, to reduce the impact of noise.

The noise is not small, but it is not unacceptable, there must be sound insulation, and the sound insulation ability is much stronger than that of high-end cars, but the external noise is very large, and it is conducted through the fuselage, and the sound insulation effect is worse in sense. If you are afraid of noise, change your boarding pass.

Sit at the front for less noise, or bring a pair of earplugs.

The location of first class and business class on the plane is relatively quiet. First class and business class are located at the head of the aircraft, and the cabin noise is relatively low. Because this position is least affected by engine or turbulent boundary layer noise, and the noisiest is the wing position, which is generally noisy in front and behind the wing.

Therefore, if you are afraid of noise, try to choose the front seat.

Aircraft noise mainly includes propeller noise, exhaust noise, jet noise, fan noise and noise caused by the fluctuation of the pressure of the attached surface layer. It will cause three impacts: 1. Fatigue the fuselage, affecting the service life and flight safety of the aircraft; 2. Affect the normal operation of the equipment on the aircraft and the comfort and safety of passengers; 3. Cause noise pollution to the ground working area of the airport and the residential area near the airport.

This is the main reason why airports are generally built in remote areas and are uninhabited. The noise generated by the aircraft during the flight has a certain impact on the aircraft itself and passengers. Considering the comfort of the aircraft, the crew will arrange the first class and business class, which are more expensive, in a less noisy location, in order to give passengers a better experience.

The small mantra of the plane seat: "The head of the plane is the quietest, and the local tyrant is directly in the first class." The safe passage was carefully chosen, and the wings were noisy in front and back.

After you can choose to come and choose, you can rely on the corridor instead of the window. "In addition, the front and rear compartments are usually safer than the middle seats, the location near the exit is safer, and the window seat is safer than the aisle position.

The head position of the aircraft is less noisy.

The plane can be divided into three parts: front, middle, and rear, the front seat turbulence and noise are relatively small, and the boarding and dissemination are fast, and the catering distribution is also faster than the family wheel, in this regard, the front seats are relatively more comfortable than the rear row.

The noise of the seats at the back of the cabin is relatively small, but the flight attendant work area and toilet are usually set up at the back of the cabin, which may be relatively noisy, and the last row of seats on the plane cannot be adjusted, so it is best to avoid this row of seats as much as possible.

Precautions for flying.

If you want to choose the right seat on the plane, you must choose it as soon as possible, because there are many people who think the same way as you. At present, most of the airlines and Xinfen are open for seat selection 24 48 hours in advance, and some airlines can choose a seat after booking a ticket, such as China Southern Airlines, which can immediately select a seat through its official app or ** after purchasing a ticket.

China Southern Airlines also issued a notice stating that it will implement 100% advance seat selection service on domestic flights actually operated by China Southern Airlines from January 1, 2019, and seat reservation can be carried out through the official electronic channels of China Southern Airlines as long as the ticket is successfully purchased.

The location of the least noise in the aircraft is generally located in the front and middle of the cabin, especially the position of the wings. Because of which positions are the farthest away from the engine and exhaust system, the noise is relatively small. In addition, the first and business class cabins of the aircraft are generally less noisy than the economy class.

However, it should be noted that the noise level of the aircraft also depends on the type of aircraft and the flight status, so the specific noise situation needs to be buried according to the actual situation.

Hello, when you take a plane, noise is inevitable, but you can choose which row is less noisy. First of all, the noise in the middle row of the cabin will be smaller than that of the front and rear rows of the cabin, because the engine noise in the front and rear rows of the cabin will be louder than that in the middle row. Secondly, the noise inside the cabin will be less than the noise outside the cabin, because the air flow outside the cabin will produce more noise.

Finally, sitting in the interior of the cabin near the window will be smaller than near the slag aisle, because the window will have a barrier to reduce some of the noise. In short, if you want to be less noisy when you take a plane, you can choose the middle row of the cabin, the interior of the cabin, and the location near the window.

You can call 12369 to complain about noise nuisance.

Examples of complaints about aircraft noiseThe Civil Aviation Administration of Chongqing made a public reply: As Chongqing's development accelerates, the demand for air transport increases. Chongqing is located in a hilly area, the surrounding environment of Jiangbei Airport is complex, and the mountains pose a great obstacle to the use of airspace.

In the next step, the Civil Aviation Administration of Chongqing will coordinate with relevant airlines to strictly implement low-noise flight measures, and study the possibility of optimizing the arrival and departure routes of Jiangbei Airport from the technical level to reduce the impact of noise.

Introduction to Aircraft Noise:

For an airplane to take to the skies, it needs a lot of power. Its own weight alone is dozens of tons, plus passengers and luggage, to fly into the sky, it needs to have high engine power and sufficient power, so the noise will also be large. In general, noise below 85 decibels is not harmful to hearing, while above 85 decibels can be dangerous.

Choose between a premium cabin or a seating position away from the wings. Discomfort caused by noise can be mitigated to a certain extent by swallowing saliva or plugging your ears with your fingers. For ***, the noise is mainly in the main rotor, tail rotor, engine and final reducer.

The sound of the plane taking off is about 110 decibels. However, depending on the distance between the airport and the place of residence, it is not necessary to reach such a high decibel level in the area. The noise loudness of the airport bridge is about 75db-95db in the elimination section.

The German Federal Environment Ministry conducted an analysis of the health status of 1 million residents over the age of 40, all of whom live at Bonn Airport in Cologne, western Germany.

The results of the study showed that men who were chronically exposed to aircraft noise were more likely to be hospitalized** for heart disease69 and women who lived in areas with airplanes were 93 more likely to be hospitalized for heart disease than those who lived in quiet areas. In addition, women who are chronically exposed to 60 decibels of aircraft noise during the day are more likely to suffer a stroke172.

Generally speaking, the noise influence range is elliptical with the airport as the center, the maximum diameter is about 9 to 13 kilometers parallel to the airport runway, and the minimum diameter is about 5 kilometers.

However, it also depends on the throughput of the airport as if it is circling, after taking off, it needs to climb to the first flight altitude in the airspace demarcated by the airport, and then fly to the destination, and climb to the specified altitude of the flight.

Factors influencing aircraft noise.

Airport noise is the convergence of aircraft noise, it is related to the type of aircraft and the number of take-off and landing, its influence range is the vast area covered under the influence of a certain height of flight, so the size of the noise pollution area, and the location of the airport, the distance from the city, the take-off and landing mode and time arrangement of the aircraft, and the layout of the runway in the airport.

Since the 50s of the 20th century, the rapid development of air transport, the high speed of aircraft and the increase of payload, making the noise of aircraft more and more loud. Supersonic aircraft can also cause a roar. When the aircraft is flying at low altitude, the flight coverage of several kilometers wide can be formed within the influence of the n-shaped wave wavefront of the roar.

Aircraft noise pollution is becoming more and more serious, second only to ground traffic noise pollution in developed countries.
