It's a while since I caught much of this programme, but the whoosh, I guess, might at least partly
be created with a notch filter. If this is at mid-high frequencies, it's a well known phenomena that
I first heard demonstrated (on a PDP-8 computer!) way back in the early 1970's when I was at the
Physics Department, Cardiff - take white noise and notch filtering it at somewhere between 8 and 10
kHz (from memory, needs checking) results in the perception of a tone moving in the vertical dimension.

I'm a regular watcher and I have noticed exactly the same! I thought it was
just some reflections from the room but it's interesting to see someone else
experiencing it.

Re odd things heard: is anyone here a regular watcher of "The Big Bang Theory" show (E4, and on various
cable channels)? There is a standard "sting" (a sort of semi-pitched noise cluster cum whoosh sort of
thing, little more than a second in length) used to transition from one scene to the next. My stereo TV (full HD
but otherwise cheap 32" LCD type) is in the corner of my lounge, and is in general not notable at all for
significant stereo effects, much less anything more "immersive". Obviously, the built-in speakers (a
generous 2 * 6W) are the typical small tinny things.
However, that sting, fleeting as it is, seems to produce a significant amount
of pseudo-surround, very much ~not~ localised to the TV, such that every time
it is really rather surprising. One day I will have to record and analyse it,
but I haven't got around to that yet. Does anyone have any idea if this is just
a random emergent feature of the sound (TV or room artifact), or has that
effect been designed into it in some discernible way?

sometimes (depending on content), the result will be surprising, but
tricks like these tend to fail on arbitrary content.
