Sorry,asking this for confirmation

Does anyone notice-or heard(Bluray--between 2:35:32-2:35:33)when Gordon opened file folder,there was a sound occur,- feels like someone throw a little rock to hit surface of metal shell--- (the surface of Bat signal light )Gordon caught that sound---thus he look at that direction where the sound came from and then he discovers
Bat signal light has been refurbished

I have checked 5 versions so far,one DVD Disk,two Blueray Disks from different TDKR Blueray product,two download version mkv file(1080p-2.47G,720p),that sound does exist.

-you have to use earphone,it comes from left ear side(left side of Screen).
