I think the interessting parts of the source are this:

/* ... */
  "vb", &visible_bell,
};

int
ding ()
{
  if (readline_echoing_p)
    {
#if !defined (__GO32__) || defined (__DJGPP__)
      switch (_rl_bell_preference)
        {
case NO_BELL:
default:
   break;
case VISIBLE_BELL:
   if (visible_bell)
     {
       tputs (visible_bell, 1, _rl_output_character_function);
       break;
     }
   /* FALLTHROUGH */
case AUDIBLE_BELL:
   fprintf (stderr, "\007");
   fflush (stderr);
   break;
        }
#else /* __GO32__ && !__DJGPP__ */
      fprintf (stderr, "\007");
      fflush (stderr);
#endif /* __GO32__ && !__DJGPP__ */
      return (0);
    }
  return (-1);
}

But I couldn't really find out were visible_bell is defined. I
think the best solution for me is to leave the setting of
"bell-style = none".
Sorry it is the first time that I take a look in some GNU source code.

I searched all the docs and the sources, that what I found:
<<<<<<<<<<<<<<<< gnu\bash1147\RELEASE >>>>>>>>
h.  The VISIBLE_STATS completion listing code now follows symlinks
<<<<<<<<<<<<< gnu\bash1147\lib\readline\bind.c >>>>>>>>>>>>
/* Define this to get an indication of file type when listing completions.
*/
#define VISIBLE_STATS
