yes i found it,thanks and i replaced the sound with a silent oneAs far as I know, either TW or AOSP have no option to choose different sound for tapping sound. It only have ON or OFF, I dont know if you can delete that sound manually.
Using any root-enabled explorer, go to system/media/audio/ui. Im not sure which sound related to tapping, so if you decide to delete it manually, make sure you make backup.
