Are plane engines getting quieter?

Yes, they have. A lot quieter. Over the past 50 years individual aircraft have reduced their noise impact by 75%. Indeed, compared with the first jet aircraft, noise from modern aircraft has been reduced by 97% on departure - a 15 decibel reduction - and 94% on arrival - a 12 decibel reduction (1).



Yes, 2026 marks a period of significant noise reduction in aviation thanks to high-bypass turbofans and Geared Turbofan (GTF) technology. Engines like the Pratt & Whitney GTF and the CFM LEAP (found on the A320neo and 737 MAX) utilize gearboxes that allow the front fan to spin at a slower, quieter speed while the internal turbine spins faster and more efficiently. Additionally, modern aircraft like the Boeing 787 feature "chevrons"—the sawtooth edges on the back of the engine nacelle—which help mix hot exhaust with cool air more smoothly, significantly reducing the "jet roar" during takeoff. In 2026, new aircraft are roughly 50% quieter than the "legacy" jets they are replacing. This trend is driven by strict "Chapter 14" noise regulations, which aim to reduce the noise footprint around airports and improve the passenger experience inside the cabin.

It might surprise you that today, aircraft are dramatically quieter than 50 years ago. A number of advancements have each helped to reduce aircraft noise, including: The introduction of modern turbojets and turbofan engines. The retirement of older and noisier aircraft.

In the longer term, after 2050, completely new aircraft geometries that use blended wing designs, and even aircraft that change shape will potentially lead to major reductions in airframe noise, greater efficiency and improved environmental impact.”

In 1990, federal law required large jet airplanes to comply with stage 3 noise standards by 1999, leading to a phase-out of the noisiest airplanes (stage 1 and 2 airplanes). Later, federal law required smaller airplanes to comply with stage 3 standards by 2016.

Departures tend to be louder than arrivals since the pilot is using more power to the engine to achieve lift.

Aircraft must fly over residential areas because of the small distances between some airports and neighborhoods. Therefore, it is sometimes necessary for aircraft to fly over these residential areas in order for aircraft to safely reach the airports.

Night flying restrictions or night-time curfews, including night flight bans, are any regulations or legislation imposed by a governing body to limit the ground-perceived exposure to aircraft noise pollution during the night hours, when the majority of residents are trying to sleep.

Besides skinny seats, slim lavatories and overstuffed overhead bins, here's another reason to loathe the back of the airplane: It's noisier than the front. The noise inside an airplane is a choice airlines and airplane manufacturers make.

During the day, when the air is warmer than the ground, noise energy from an airplane staying in the air, so while you can still hear it, it seems quieter. Conversely, at night, when the ground is warmer than the air, the noise is drawn down, making it seem louder.

The Federal Aviation Regulation (FAR) Part 91.119 indicates that, except when necessary for departure or landing, the minimum altitude over urban areas is 1,000 feet above ground level (AGL) and 500 feet AGL over rural areas.

The military, in addition to following its own flying rules on low-level altitudes and airspeed, also follows those in Federal Aviation Regulation 91.79 which states that no plane may fly closer than 500 feet from any person, vessel, vehicle or structure.

MORE DETAILS

Generally speaking, flying at higher altitudes means higher airspeed because of less drag. Of course, the type of aircraft you are flying will come into play as you work with flying at different altitudes, as will the amount of weight you are carrying. But realities of aerodynamics and physics remain the same.

Question: Right after takeoff, it often seems that the pilot slows down and the plane drops somewhat. Why is that? I have noticed that it is pretty consistent. Answer: The sensation of slowing down is really one of slowing the rate of acceleration; this is due to reducing the thrust after takeoff to the climb setting.

While the average age of a U.S. domestic commercial airliner is 11 years old, it is not uncommon for aircraft to still be in service at 24, 25, even 30 years old.

Many people are afraid of flying in airplanes, but they shouldn't be. Flying is actually one of the safest ways to travel. In fact, when measured per mile, flying is actually ?far?safer than driving, or travelling by train. Not only is flying the safest ?mode of transport?, but it is also the fastest.
