I guess this section in the aircraft.cfg defines the trigger for playing that sound.

[GPWS] max_warning_height         =  1200 sink_rate_fpm              = -1500 excessive_sink_rate_fpm    = -2000 climbout_sink_rate_fpm     = -1500 flap_and_gear_sink_rate_fpm= -1500

So if you are looking for a less general solution (renaming the file disables it, even if it would be played in the right situation, on every plane which uses it), try altering the values there.
As Lou pointed out in another thread, this warning is intended to be played when you are sinking after takeoff while the approach sinking of course is correct.

I always understand "don't think!" and followed this advise since hearing it. :D


Now, if you want to disable that sound just on the CS 727 (and leave it available for other addons and planes, that's my only concern with Lou's solution), you can also go to \SimObjects\Airplanes\CS_B727-100\sound and open the sound.cfg.

[GPWS_Dont_Sink] filename=silence maximum_volume=10

and save it (make a backup first, the only file that gets processed is the one named "sound.cfg").

This defines the sound "silence" to this event. Since there isn't any sound "silence", nothing can be heard. Some devs even drop a silent file in there which gets played then.
If the event itself isn't defined and the plane has a flag in the aircraft.cfg that GPWS is available (which the 727 does) you will hear the default FSX sounds in those situations. That's what's happening on your system.
By defining the custom sound in the sound.cfg, you can override them.
