Video: Can You Hear Big Ben's Chimes On A Radio Before You Do For Real?

Mark Mason's rather superb book The Importance of Being Trivial includes this fact: Because radio waves travel at the speed of light, which is faster than the speed of sound, in theory you should be able to hear Big Ben's chiming on an FM radio BEFORE you do if you're standing directly below the clock tower.

But is this true? We went to Westminster Bridge to find out.

To hear for yourself, it's best to watch this video using a pair of stereo headphones.

Vicki is excellent in this video! Nice work.

And don't forget that all the "bongs" will be differently timed as to wether you are listening on FM or Digital Radio or Digital TV via Satellite or Freeview or viaThe internet. Just like the Greenwich "PIPS" are different on all these sources!

Neat experiment, although I hate to break it to the crew, the 80's called, they want their boombox back. Haha! :)
