Yes - from personal experience. I've mentioned this before in sursound but it would be quite a long
time ago (6-8 years). About ten years ago I was watching a game of Pelote in Biscarrosse (near
Bordeaux, France). It happened that I was closer to the Fronton (wall) than I was to the players and
that the sound of the ball hitting their pelatas (bats) was very, very similar to that of the ball
hitting the Fronton. (I worked all this out afterwards). From the angle I was at, sometimes the ball
seemed to hit the Fronton and curve back to hit it a second time before bouncing back to the
players. Not being familiar with the game, I thought it was some amazing trick shot done with some
weird form of spin - until, that is, I found that the people I was with could not see it. Despite
the fact that it was clearly an illusion, I couldn't stop myself seeing it when at a particular
point on the edge of the pitch, even after I had figured out that what was happening. This was that
I was hearing the bat/ball contact sound shortly after the ball/fronton contact sound and, because
of the close similarity of the sounds in level and timbre I was mentally interpreting this acoustic
event as meaning the ball had hit the Fronton twice. It may be that, because my ears are better than
my eyes (I'm very short sighted), I'm more prone to something like this, though I have to say that
I'm not really aware of any other occasions, but perhaps I just ain't become aware of them. It was
definitely a weird experience.
