They are proposing 85db at ground level. That’s as loud as a gas lawnmower, except it would sound like an explosion.
Even current aircrafts’ air braking is loud enough to be annoying as hell (to the point where people routinely complain and force airports to move approach routes).
The air brakes sound something like “dew-yoooouuuuu”. Not sure what the actual name of the hated thing that makes the noise is.
That's the sound of changing configuration from descent to landing. Involves increasing power to the engines which is the main source of the sound involved.
Properly executed landing in airliner doesn't use airbrakes until touchdown (where they are used among other things to ensure airplane doesn't accidently lift from runway and are triggered by pressure sensors on main gear).
To quote a certain pilot's response to ATC: "Air brakes are for when I fuckup, not for your fuckups"
so it would be about as loud as something most suburban homeowners do on a weekly basis during the summer, but for a much shorter duration? not really making your point here... that sounds like a fair tradeoff to decrease flight times.
