Is Boeing louder than Airbus?
However, newer aircraft like the Boeing 787 are significantly quieter than the Airbus A330 largely due to cabin noise reduction, engine nacelles & light weight design.
What is the quietest commercial airliner?
The quietest commercial airliner is the Bombardier CSeries, more specifically the Bombardier CS100 with a EPNdB margin of 18–21 (depending on weight & engine model). The CSeries also produces the lowest noise levels during a flyover with a silent 75.5 dB, something “unheard” of in the commercial jet industry.
What is the quietest part of a plane?
The front section, especially seats that are placed before the jet engines are the quietest area of the plane.

Are private jets quieter than commercial?
Typically, private jets are quieter than commercial planes both inside and out. The engines on a commercial plane are much more powerful and can generate sound levels up to 140 decibels and can be heard from miles away on the ground.
Which is quieter 787 or A350?
The A350 is quieter While the 787 is already significantly quieter than other Boeing models, the A350 is on par with the A380 in terms of how quiet it is in the cabin. That really can make a huge difference when it comes to overall wellbeing and being able to sleep.
How quiet is the A380?
Airbus A380 is the quietest aircraft with a cabin noise level of 56.0 ± 2.2 dB (2σ). For narrow-bodies, Airbus A320 and Boeing 737 have a noise level of 68.5 ± 3.4 and 69.6 ± 1.4 dB, respectively.
Which part of the plane is the quietest?
What kind of plane is a 727?
The Boeing 727 is an American narrow-body airliner produced by Boeing Commercial Airplanes . After the heavy 707 quad-jet was introduced in 1958, Boeing addressed the demand for shorter flight lengths from smaller airports.
Is the Boeing 727 the noisiest commercial jetliner?
The 727 is one of the noisiest commercial jetliners, categorized as Stage 2 by the U.S. Noise Control Act of 1972, which mandated the gradual introduction of quieter Stage 3 aircraft. The 727’s JT8D jet engines use older low-bypass turbofan technology, whereas Stage 3 aircraft use the more efficient and quieter high-bypass turbofan design.
Is the Airbus A350 quieter than Boeing 787?
Airbus claims the A350 is “five decibels quieter than competing aircraft [the Boeing 787], and up to nine decibels quieter towards the front of the cabin. This means four times less noise.” This, of course, is without Airbus actually releasing their data. Where to Sit? In a word? First class.
What happened to the Boeing 727?
The 727 had many iconic features such as the steps, or ‘airstair’ at the back of the 727 which helped to embark and disembark passengers at remote destinations, and the full span high devices. Both aircraft were noisy in their early guises and retro fitted hush kits were mandated to deal with the problem. The aircraft did have their issues.
