This fact makes me suspicious that it might be an instance of comb filtering going on, which is often caused by the interference of a signal being summed with itself with a small delay. It is subtle and may cause the sensation described above, but I'm not really sure.

It's possible that the round surface is partly responsible for the width of the effect but it's pretty unique in my experience to inflated rubber balloons.
