How loud is the 787?
How loud is the 787? 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.
Is Boeing 787 loud?
The 787 is on average up to 7 dB quieter on departure than the 767, and up to 8 dB quieter than the A330 aircraft. The results also confirm that the 787 is up to 3 dB quieter on arrival than the aircraft types it is intended to replace.
Can the 787 fly at the speed of sound?
However, did the 787 truly fly supersonic relative to the air? The answer is no. The 787 is a widebody passenger aircraft capable of flying long distances at a cruise speed of 0.85 Mach (652 mph/1,050 kph).
What is the maximum altitude of the 787?
During the flight the 787 reached a top speed of 180 kn (333 km/h) and maximum altitude of 13,200 ft (4,000 m).

Which is quieter 787 or A350?
It has been reported that the A350 is quieter than the B787, primarily due to the automatic Noise Abatement Departure Procedure (NADP) for the optimization of the engine thrust and flight path to reduce noise and the fuel-efficient engine. The other giant airplane, A380, is also known to have a quiet cabin.
What is the loudest airplane cabin?
The decibel levels do not differ dramatically between aircraft: the loudest aircraft, the Boeing 737, is 4.9 decibels louder than the Embraer regional jet. However, because of the logarithmic scale used in reporting decibels, this means the Boeing is about 50% louder than the Embraer aircraft.
