Over one million views, he's an internet sensation.
Oh, oh, where is McCork?
He usually bursts in doing something crazy by now.
Good morning, Colin. Good morning, Dr Knowles.
I take it you've seen the video then, Professor?
Yes, I've seen the video and I am not impressed.
It's only a bit of fun, Professor.
Well, I don't find it one bit funny
and I'd like to assure that my days of acting the fool are over.
-We're live in five, four, three...
This is Brain Freeze!
With Dr Knowles,
Colin the floor manager.
Hello, everyone, you're very welcome to Brain Freeze.
And it's time for...
Today's Big Question!
Today we're asking why does my voice sound different recorded?
-First we need to look at how we hear...
-Hang on, Doctor.
If you don't mind, I'll take this one.
OK, off you go.
When we speak or sing, our vocal cords vibrate.
This vibration creates invisible sound waves which travel out
in all directions before returning and entering the ear canal.
The signal is then boosted or amplified in the middle ear
before reaching the inner ear, where it's converted to nerve
impulses that the brain perceives as sound.
Over to you, Dr Knowles.
Er, Dr Knowles?
-We happen to be live. Hello?
Erm, let's take a quick break.
And we're clear!
Now, Dr Knowles, I really need you to focus on the
second half of the show, OK? The lights will come up...
Yes, boss, ratings are down. I understand.
Viewers want the silly McCork back.
I never thought I'd say this but I wish we had the old McCork back.
Honestly, I don't know how I work with these people.
-Places, everyone! We're going live!
We've seen how the sound of our voice enters our ears through the air,
but we also experience it in another way, through our bones.
When we speak or sing, sound also travels from the vocal cords,
directly to the inner ear through the bones in our head.
You can hear what this sounds like by blocking your ears
and speaking at the same time.
Because the sound is travelling through bones,
the low bass frequencies are enhanced and it sounds muffled.
-Are you all right, there, Professor?
I beg your pardon. Where were we?
Is it time for the answer yet?
Today's Big Answer!
So you're used to hearing your voice from a combination of both
external and internal sources but when you hear your voice
recorded and played back, the internal sound is missing.
And that's why you perceive it as sounding different.
-That's all for today, folks.
-Working with amateurs, honestly.
-Quick, Dr Knowles!
-I think our problems are over!
-Oh, the boss is going to love this.
-What's so funny?
What are you laughing at?
Actually, it is kind of funny.
Well, as the old saying goes, if it ain't broke don't fix...
Doctor Knowles and Professor McCork open the studio doors for an explosive episode of the show that tries to get to the bottom of some of life's most massive science questions.
Knowles and McCork ask, why does my voice sound different recorded? After a video of his silly behaviour goes viral, McCork attempts to take his job as a professional scientist seriously for once. What could possibly go wrong?
