Explore: Cabin Noise

Aerodynamic noise—from the airflow around the surfaces of the aircraft, especially when flying low at high speeds. Noise from aircraft systems—cockpit, cabin pressurization

problem for passengers was the very high noise level inside the cabin, measuring at least 90–95 dB on average. The noise came from the engines; unlike Concorde

the dashboard, Active Noise Cancellation (ANC) pumps an opposite-phase sound through the audio speakers to reduce cabin noise, and Active Control Engine

(including all Series 400s) include the Active Noise and Vibration System designed to reduce cabin noise and vibration levels to nearly those of jet airliners

power was limited to 75% to reduce cabin noise. Some aircraft have a propeller synchrophaser to reduce cabin noise and vibration. The FAA granted certification

with serial number 94. Cabin pressurization is raised from 6.4 to 7.1 psi (0.44 to 0.49 bar) and improved insulation cuts cabin noise by 3 dB. At FL 310,

about noise, TCA engineers developed a cross-over for the fuselage-side exhausts that reduced cabin noise by 6-8 decibels. "In the cabin, noise is reduced

propellers, and propeller synchrophasing, all in an effort to reduce cabin noise. This model also had PT6A-21s; the first production C90B was fitted with

G-IV. The three zone cabin is similar to the G-IV, smaller than the Global Express, while its dispatch reliability, cabin noise and fuel efficiency compare

520 m (5,000 ft) up to 12,000 m (39,000 ft). It has 50% less cabin noise, 50% more cabin area and volume, larger windows, bigger overhead bins, and 60 cm
