I've been up all night. And surprisingly, i'm not tired....

Meh, it's a good thing

[xJaix]

I don't feel ready for this at all! I do, but not as much as I would like to be ready.

 

[Takuto]

haha, I'm already in my jeans and jacket ready to tackle this damn exam!

I'm going to try and be confident and see how far it gets me.

 

[Takuto]

lol, you sound really confident, good luck with the band 6

im just starting my option topic now, hehe

 

[dolbinau]

lol *awake.*

 

[Takuto]

lol the bio god is here

step back people

 

[xJaix]

lol, you sound really confident, good luck with the band 6

im just starting my option topic now, hehe

haha, confident? No way. I wish I was, unfortunately I don't remember all that much.

Gotta continue studying. yay.

 

[Takuto]

Btw, what is that 'sound shadow' thing you keep mentioning?

 

[Takuto]

haha, confident? No way. I wish I was, unfortunately I don't remember all that much.

Gotta continue studying. yay.

dont worry, bio is all luck

no sane person can remember it all..

unless you're dolbinau

There are heaps of amazing people on this forum Danz and Midifile for example who know this course is so much more detail than me .

Assuming you do communication- Sound Shadows are really stupid/basic. It's just saying that your head blocks soundwaves coming towards it (A shadow on the other side of your head), so obviously the amplitude of the sound will be less in one ear and you can tell the direction of the sound.

Stupid, but they've never asked it before so maybe it'll be good for 1 or 2 marks.

Other communication items to make sure you know:

* Medulla Oblongata/Cerebrum/Cerebellum

* Path of a sound/energy conversions in the ear (Basically sound>mechanical>electrochemical)

* Detection of sound by fish, insects, mammals

These apparently haven't been asked before.

 

[Takuto]

oh okay, thanks

better to be safe than sorry

yeah, you guys are awesome, lol. what a nice thread

does anyone have a diagram of the areas in the brain involved in sight and sound perception?

 

[dolbinau]

There is one here:

You only need to know sight/sound/speech.

 

[Takuto]

Sound >

Pinna - auditory canal

Mechanical >

tympanic membrane - ossicles - oval window

Electrochemical >

Corti - hair cells - auditory nerve - brain


lol this is from memory, havent done it since trials

i think some parts are wrong

thank you =]

* Medulla Oblongata/Cerebrum/Cerebellum

* Detection of sound by fish, insects, mammals

haha no idea on these

 

[dolbinau]

I think that's right. cool. Is the round window related or is that just to relieve pressure? I have conflicting sources.

 

[Takuto]

its a 'membrane between cochlea and middle ear'

sound doesn't pass through it i believe, its just to allow and relieve pressure
