DW, does the sim produce a lot of noise when “stalled” and held in the stall with high RoD?
(It was reported in an earlier thread that somebody who had heard the CVR said that the air rush noise in the AF447 cockpit was very loud, and may have added to the PF confusion by reinforcing any belief he might have had that their problem was overspeed, as that too would have been noisy; and the pilots had probably never heard either noise before in the aircraft, and may not have heard both in the sims.)
As noted previously, I am one of "those" engineers responsible for developing the sound models used to generate the sounds in simulators (many, many types now). There would be no vertical speed component contributing to the noise signature in the sim, unless the company producing that sim extrapolated way outside of the available sound data supplied with the aircraft data package. The key driver for aeronoise is CAS modulated by Mach factor.
