Program About the Physics of Sound

[Ed209]

I thought some of you might find this interesting, and educational. It's on BBC iplayer unfortunately, which means it's only available in the U.K., I think?

Episode one is the science behind sound. Episode two, which I'm watching now, details how our ears pick sound up.

Thanks for this @Ed209 I have downloaded both episodes so I can watch it later.
Much appreciated.

They are both good Michael, but episode two in particular highlights some things that even I didn't know. Our outter ear folds change specific frequencies as a broadband wave hits them, making certain frequencies louder than others. This allows us to directly identify if sound is above or below us. They prove this by putting plasticine in the outter ear and then testing the presenter with a series of claps. Interesting stuff.

Thanks again Ed, it looks very interesting and looking forward to watching it...

At the end they give a link to some extended reading on the auditory system, which can be found here:

The links on the left give some insight into each part of the auditory pathway, and how sound is processed etc

Was going to PM you, watched last night but will watch it again...loved the 3D imaging.

Did you see both episodes Candy?
