Hi,

The vibration/turbulence sound the speedbrakes generate, continue until after landing when reversers are off but SPD BRK is still armed and thus deployed. Theoretically, this sound should become less audible the slower the aircraft becomes and should not be heard at all after landing or when the aircraft is taxiing.

Exactly, really annoying and Echo 19 used the exact same sample for the a350 and the a340, I don't exactly think we would hear it during cruise or descent..

I also have this as a major sound bug.  In flight it keeps increasing until it's at a deafening level.

This is the iniManager version, 1.07, MSFS2024

In the real aircraft you really can’t hear the speedbrakes in the cockpit at all. There is some airframe vibration, but not much audible. I really hope this could be adressed, as I often find myself decreasing my speakers’ volume whenever I use the speedbrakes.
