I higly doubt temperature will make any greater difference.

That's what I'm saying.

If you mean travel further wouldn't that just change the volume?

I guess(?) sound does travel slower in colder air.
But with warmer air, I believe the sound disperses faster.
I would guess(?) the denser (colder) air would carry the original audio wave more accurately.

When I wake up and immediately grab my headphones and listen to them the sound plays faster than it would regularly. I can't be the only one who has noticed...

In the morning your consciousness is slower than normal. When your consciousness speeds up the sounds get slower and slower. If you consciousness really speeds up, you have achieved 'bullet time'.
 
As good an explanation as any.

    Brain waves

1. Delta wave – (0.1–4 Hz)
2. Theta wave – (4–7 Hz)
3. Alpha wave – (8–12 Hz)
4. Mu wave – (8–13 Hz)
5. Gamma wave – (25–100 Hz)

This looks a lot more like a guide to kundalini and astral projection than logical answer. I don't believe in stupid theories like that.

Sound travels faster in dense air, But that does not mean anything in this case. Increased soundwave velocity only makes the sound reach the ears faster, it has no effect on the  way we perceive tempo (if this is what you mean). The headphones still send the soundwaves in the same intervals. There might be some temperature effects on the hardware but that would most likely distort the sound, not increase the tempo.
 
I don't know what causes this, but I have noticed that the perceived tempo is often affected by the level of tiredness I personally get the illusion of a faster tempo when I'm very tired, which might be the case for you in the mornings. My guess is that it has something to do with the way our brains decode the information they receive from the ears. But as I said, I don't know for sure.
 
Please correct me if something I wrote is stupid =)
 
Cheers!

Forgot to write something...
 
The faster speed of sound in cold air should result in increased frequency and wavelength. This would only make it sound different.
 
velocity = frequency * Wavelenght

A lot of audio perception is based on your mental state. A lot of people listen intently and have their best aural experiences at night because they're relaxed and the outside noise level is diminished.
That's how I feel anyway.

And to this I say certain psychoactive substances can *ahem* enhance the experience. I kid you not, once with my ha-s500 I could hear the silent lapses between the music, when the driver wasn't producing sound I suppose. After that I tried honing in on music on my desktop rig and music sounded much more fluid.

Well according to this book I read, you hear best in the evening and in the morning... or did they say sight now that I think about it... Well anyways, it said our ancestors used to have to hunt or defend at night, so they had to have better senses at night and around morning time. Yeeaah... Not sure how that helps the thread but its something. I think it's just that your ears were so you used to not being used, or hearing nothing, that they're sort of shocked.

This is an interesting topic actually. I generally find in the mornings, I don't hear too well so I don't do any critical analysis in the mornings. I attribute this due to my ears not "waking up" yet. Then talking to Musica Acoustics (who's a musician in his spare time) mentioned that it's the same for him that he doesn't play on the mornings.

Don't think I've heard sound travel "faster" in the mornings though. I don't mean any disrespect but wondering if its the brain that's not "woken up" yet & psychologically has not caught up with what we heard fast enough - mental alertness.

Random question AnakChan but what is a moderator? It's your title.

 

[Trunks159]

Sound actually travels faster in the morning. Since the temp is lower, molecules vibrate less making sound easier to travel.

Mean's I kinda help other moderators & administrators keep an eye on things & help in maintenance of Head-Fi - spam, move threads in the wrong category, etc. (janitor if you will ).

Ah ok. Thanks.
