PEEEEEEP

Hello,

This "morning" at 6 hours and 48 minutes I did another recording... (I
wanted to make a Dirt 2 video first so it got a bit delayed).

This is what I did:

1. Shutdown the pc.
2. Unplugged the case fans.
3. Opened the case.
4. Placed the mic on the x-fi breakout box to give the mic levitation near
the cpu fan.
5. Rebooted pc.
6. Recorded the sound.

The result is in this folder:

http://members.home.nl/hbthouppermans/PEEEEEP/

To be precise in this file:

http://members.home.nl/hbthoupperman...cember2009.mp3

At 0:38 I stop the cpu fan, then you can hear it spinning more slowly and
making less sound... then after a few seconds I let it run again...

I think later on there is some kind of very high peep sound hearable. But
it's difficult to recgonize between the main humming sound and the air flow
sound.

So there are a couple of sounds on this recording:

1. Main humming probably caused by power supply fan, graphics fan, cpu fan,
and motherboard electronics, maybe even fridge.

2. Air flow sound produces by power supply and graphics fan but mostly cpu
fan 3000+ RPM !

3. A high peeping sound at some parts of the recording... almost not
hearable... must play the sample really loud ?!

The third sound is very strange.

I also discovered something else... MP3 does not compress silence well... I
cut out the silencent/buffer part and the file size went from 5 MB to 1 MB !

I will leave it at that for now... more analysis is needed to extract the
peeping sound possibly.

For now I have three explanations for the peeping sound:

1. It's the CPU FAN metal sleeve rubbing against other metal because of lack
of oil.

2. It's the CPU Airflow creating the high pitch noise.

3. It's my own brain which experiences the sound as to loud and starts
playing a peep inside my head ?!
(Like a pain signal or so)

I doubt it's 3... it's probably 2 or 3.

Anyway the end result is that this high pitching peeping noise is "copied"
by my brain or ear for some reason... and my brain or ear starts playing
this sound non-stop.

Maybe this is a form of temporarely high-pitch-sound-ear-damage ?!?

Is such a thing possible ?!

"High-pitch sound creating ear damage ?!?"

Weird.

Could also be the ear resonating at the same frequency... or simply brain
playing same signal over and over...

Bye,
Skybuck.

Ok,

Thanks to goldwave and my smartness ! =D

I managed to isolate the sound... it's quite surprising !

Here is how I managed to extract it:

1. First the humming and airflow must be filtered out.

The humming and airflow have a low frequency noise.

So by cutting of the frequencies of say 0 to 5000 (?) this gets rid of it.
(Can't remember if it was 2000 or 5000 or 10000 just keep trying until it's
gone).

2. Now the volume must be increased because the high pitch noise is only
hearable if the volume is increased for some reason...

So next apply a "change volume" operation and increase the volume with
another 10 procent.

The result is this file:

And that's more or less what I hear in my head the whole day !

So the prove has been delivered...

(This was on a first attempt... maybe it can be extracted even better by
using a different bandpass filter setting...)

Bye,
Skybuck.

Actually there are two more possibilities I can think of:

3. The Denon receiver has something to do with it... maybe it's equalizer
?!?

4. The fans of the case have something to do with it when they on medium ?!?
Maybe too much noise...

Lastly:

5. X-Fi "bass redirection ?"

I still think it's number 2 though...

Also very remote possibility:

6. Outside building fan not giving my ears enough rest...

But I still think it's number 2 though ! =D

or

7. "7.1 surround sound sets bad for ears ?"

Hmm me go google that !

I hear a little zooming sound in my ears...

I can think of two possibilities:

1. Too much gaming (Company of Heroe's + Left 4 Dead 2 + Dirt 2 )

2. High pitch sound coming from stock AMD X2 CPU Cooler ?!

I think it's actually number 2 ?!

Wacky !

Oh well.

If the peep don't go away after I stop gaming... when I stop gaming... I
might have to do something about... ****ty ?!

Maybe trying to oil it ?!? But is it sleave bearing or ball baring fan...
hmmm...

Otherwise other cpu cooler needed but I already spent so much money on
this PC... I really don't wanna spent any more on it... and I wouldn't
know what cpu cooler get... this is pretty ridicilous.

My next computer is gonna be an ultra low heat computer ! Me pretty sure
about that ! :P*
(But must still have some power !)

Try going outside and see if you still hear it. How long has it been
since you were outside?

...."outside?? what is that??"

That's the part of your home on the far side of the garage door, where the
trees and flowers and chirping birds live. ;-)

Hope This Helps!
