00:07

gesture you see when a song greets you today's question is the height of a

sound wave is known as the what and here are your potential answers okay well here we

00:16

go..... well we'll do you a favor and eliminate

00:19

the obviously wrong one first seeing as cochlea is the nail shaped portion of the

00:24

inner ear there's no way it has anything at all to do with the technical measure

00:28

of a sound wave one down four to go and remember slow and steady wins the race [A slug slowly moves]

00:31

here.......Could it be D energy, well sound energy density is calculated by this

00:39

mathematical calculation where p is the sound pressure, v is the particle

00:44

velocity, c is the speed of sound and well it's a lot more complicated than [Man rolls his eyes]

00:49

just the height of a sound wave so we can lose D now what about E; volume

00:53

well volume isn't even a scientific term our purposes that option might as well

00:58

not even exist so cross out E. That leaves us with amplitude and frequency

01:34

and downs it doesn't measure the height which is what we're looking for so B

01:37

ain't nothing but a hound dog the height of the wave is referred to as amplitude

01:42

the taller the wave, the louder the sound so in the case of our baby and the king [A baby in a crib and Elvis holding a guitar]

01:47

here you can clearly see which one is louder and which one you're giving back
