I've got two questions on some of this, which I hope someone out there might be able to help with. The first relates to this part of the article:
What the loudspeakers relay to the athletes is just the Starter's verbal commands, not the "bang". That sound still travels through the air from the gun to the ears of the athletes. And it even has to be like this! Because if the "bang" would be coming through both loudspeakers and air the athletes would be experience two distinct shots, which would then be interpreted as a starting "bang" followed by a recall!!
My first question is if this is true. See, I always thought - based on what I read - that the sound of the gun DID come through the loudspeakers as well as 'directly' from the gun and the athletes did hear two 'bangs'. Have I been mistaken?
The funny thing is that in the chart at the bottom of the article, the distribution for the races in 2000 looks to have a peak at around 0.14 seconds and a peak at 0.18 seconds, as if some athletes responded to the sound through the loudspeakers, at around 0.14 seconds, and others responded to the actual sound of the gun, a few hundredths later. That is, the distribution seems to verify what I had previously thought was the case. Of course, there is not a lot of data points, so it could just be 'noise' in the data.
My second question is from this part:
... the Olympic Starter chosing to position himself extremely far away (from the TV it could be estimated that he was perhaps 20 metres from the nearest runner)!
in Atlanta 1996 when the Starter was not so far away as in Sydney the loss was still 2-3 hundredths,
I have now watched the footage of both the 1996 and 2000 race on youtube a LOT of times and I cannot tell where the starter is among all those people at the side. Can anyone see the starter in either race?
Also, did the position of the starter really change that much between Olympics? The starter is obvious in this footage from 1980, but I have not found the starter in any other footage.
If anyone has any photos, footage or anything on where the starter was positioned for any of the sprints from any Olympics then that would be great!
Thanks in advance!
