    As am I, although my older brother owned the system.

    I remember it too and it has come back. It is now called 4.0 surround sound. Heck, all the surround sound configurations are variations on the same idea.

    It’s a shame we only have two ears! Although we sense low frequencies through our bodies. My grandfather went to a theatre in London, 120 years ago, where they vibrated the seats at the dramatic moment. Bring that back!

    It actually seems quite miraculous to me how much we can tell with just two ears. Apparently we can tell whether a sound is coming from the left or right by the time the sound arrives at each ear (plus the fact that the skull absorbs some of the higher frequencies, so that there is a slight change in the sound). And what I found really interesting is that apparently when a sound is coming directly from in front or behind us (so that there is no gap between the ears), we reflexively turn our head slightly to create a gap so that we can tell if it's coming from the front or back.
    As above, so below

    I think I experienced that more recently. There was a Disneyland ride that used vibrating seats (or maybe the whole stage), though apparently it doesn't exist anymore. I rode it at Tokyo Disneyland a long time ago, but not 120 years ago!

    I saw the movie Midway in Sensurround circa 1976. Although that seems like 120 years ago.

    I don't remember very clearly, but I may have seen that as well. I definitely think I saw the pilot of Battlestar Galactica, which also used Sensurround. And it's possible that I saw Earthquake, but those movies were released when I was like 12, 13, or 14 years old, so my memory is a bit faded...

    Ears never cease to amaze, nor to communicate to the “old” brain even when we are asleep. Then the cocktail party effect where we can focus on a speaker despite the confusing sound level. As soon as you use microphones you realise how much we filter out in normal listening. Not just when drinking cocktails.

    For a sound coming from the side, and a 7" wide head, it takes about 12ms for a sound to move from ear to ear. At 30 meters per second, it only takes neurons 6ms for a signal to travel ear to ear. That leaves plenty of time for calculating a sound's source, especially if your hardware is set up to do just that.
    BTW, I still wear velcro shoes.

    Hi Squink,

    At about 1125 ft/sec through air, It take sound about 7/12 X 1/1125 = 0.5 mSec to travel 7", not 12 mSec.

    Cheers,

    Sadly, this clip doesn't have the reply:
