0:05:29 > 0:05:30OK.
0:05:30 > 0:05:33We're making a sound-activated dance floor,
0:05:33 > 0:05:35but we need to know how a microphone works.
0:05:35 > 0:05:37A microphone?
0:05:37 > 0:05:41Well, sound is a type of energy made by vibrations,
0:05:41 > 0:05:45- and a microphone turns those vibrations into electricity.- How?
0:05:45 > 0:05:47Well, if you must know,
0:05:47 > 0:05:50inside a microphone is something called a diaphragm,
0:05:50 > 0:05:53a little disc that vibrates when it's struck by sound waves.
0:05:53 > 0:05:56These vibrations are converted into electricity,
0:05:56 > 0:05:59and a wire connected to the diaphragm carries the electricity to
0:05:59 > 0:06:03an amplifier. That makes it bigger and pumps it into a loudspeaker,
0:06:03 > 0:06:05where there is another disc.
0:06:05 > 0:06:08This one does the opposite of the disc in a microphone -
0:06:08 > 0:06:11it converts the electricity back into sound waves.
0:06:11 > 0:06:14Oh, right, so it's electricity that moves sound to speakers
0:06:14 > 0:06:16and can make make it louder?
0:06:16 > 0:06:18That's it, exactly.
0:06:18 > 0:06:19- It's brilliant, isn't it?- Di.
0:06:19 > 0:06:22It means you can hear quiet things like a trickling stream.

0:06:25 > 0:06:27Oh!
0:06:27 > 0:06:29Oh, no! My beautiful mountain!
0:06:29 > 0:06:31Or a flock of birds flying off.
0:06:31 > 0:06:33What flock of birds?
0:06:35 > 0:06:38Or even the rustle of autumn leaves.
0:06:38 > 0:06:42Well, I suppose you could hear the rustle of autumn leaves.
0:06:42 > 0:06:46Stop getting me to say stupid things!
0:06:46 > 0:06:48- Thank you, you've been a great help.- Di. Bye.

0:17:34 > 0:17:36Hello, Major Cake?
0:17:36 > 0:17:40Have you, that's very forward of you, you don't even know me.
0:17:40 > 0:17:42If you did, you'd know that I don't like cake.
0:17:42 > 0:17:46No, Major Cake, it's me, Ed Petrie, from CBBC?
0:17:46 > 0:17:50I need your help again. We've got a voice-activation machine.
0:17:50 > 0:17:53We need to trigger three things, but when Sarah sings into it,
0:17:53 > 0:17:56it only triggers one thing, even when she sings louder.
0:17:56 > 0:17:57Is the machine broken?
0:17:57 > 0:18:01Well, some voice-activation machines work on how loud you are,
0:18:01 > 0:18:05but some respond to pineapple upside-down cake. I mean, pitch.
0:18:05 > 0:18:08It sounds like yours is programmed for pitch.
0:18:08 > 0:18:09What's pitch?
0:18:09 > 0:18:12Well, it's nothing to do with pineapple upside-down cake,
0:18:12 > 0:18:17that's for sure. Ha-ha! Hmm. No. It's to do with musical notes.
0:18:17 > 0:18:23High pitch is up like this, and low pitch is down like this.
0:18:23 > 0:18:25Right.
0:18:25 > 0:18:28Sound comes from vibrations which travel in sound waves.
0:18:28 > 0:18:31Lower-pitched musical notes have vibrations that happen
0:18:31 > 0:18:34less frequently than higher-pitched notes.
0:18:34 > 0:18:36Listen to this.
0:18:36 > 0:18:43# Do, re, mi fa, sol, la, ti, do... #
0:18:43 > 0:18:48On that musical scale, re is lower than sol, you see?
0:18:48 > 0:18:53- Er, sort of.- The lemon drizzle cake, I mean, voice-activation machine,
0:18:53 > 0:18:55can detect the different pitches, so can tell
0:18:55 > 0:18:59what note you are singing and will trigger when you hit the right one.
0:18:59 > 0:19:03Right, so we need to work out what notes our machine recognises.
0:19:03 > 0:19:08Correct, you need a voice-activation testing machine.
0:19:08 > 0:19:11- Great. Thanks, Major Cake. - No problem.
0:19:12 > 0:19:13Did you just mention cake?
0:19:13 > 0:19:16No, I didn't mention cake.
0:19:16 > 0:19:19Stop mentioning cake!
0:19:19 > 0:19:21Disgusting!
0:19:24 > 0:19:28- Oucho, I've never smelled anything like it.- Shh! Shh!
0:19:28 > 0:19:32Panic over, people. Major Cake said that some voice activation machines
0:19:32 > 0:19:35- recognise pineapple upside-down cake.- Huh?- I mean pitch.
0:19:35 > 0:19:38If we test our machine, we can see which notes trigger it.
0:19:38 > 0:19:42What we need is a voice-activation testing machine.

0:19:53 > 0:19:57- Would you like to know how it works? - Yeah.- Good, I'm going to tell you.
0:19:57 > 0:20:00There are eight notes on our musical scale, we need to find out
0:20:00 > 0:20:03which ones trigger our voice-activation machine.
0:20:03 > 0:20:06So I've rigged up these funnels on here. So your job is
0:20:06 > 0:20:08to sit under them and sing scales,
0:20:08 > 0:20:11and when you hit the right notes, slop will be released.
0:20:11 > 0:20:15I'm sorry, but it's the only way we can get the information we need.
0:20:15 > 0:20:18Oucho, your job is to write down what note it was.
