I am aware that sound is caused by vibrations. When i listen to my I-pod, are vibrations sent through the cable? If so how?

The sound of....coffee Has anyone else noticed that when they stir their coffee (or tea) the pitch of the sound (of the spoon on the cup) increases and then levels out? Why-why-why?!

Would a piano made from ice work and what would it sound like if it did?

I saw an advert for a certain alcoholic beverage, in which the main character make a piano from ice and them plays it, I was wondering if this would be possible?

If it would work with as much of it made from ice as possible... what would it sound like? What is the limit of the parts that can be made from ice and the ice pisno still work?

How is my router making noise? I've had both switches, and a wireless router that make a high pitched eletrical noise. What I wonder is how the noise changes/is corelated to network activity? The noise will be bursty in line with any network activity. in a solid state device what is causing that?

What sort of vibration would be able to hold a mass amount of water Okay, so I have been studying structure, and, correct me if I am wrong, does the universe give a perpetual sound or vibration? if so, could that sound be used to hold molecules together, i.e. water?

How can we sing in tune? It's well known that we hear our own voice quite differently to how other people hear it due to bone conduction of sound. How then do people sing in tune? and how do some people fail to hear that they are out of tune?

Why do cars make the same characteristic sound when reversing?

In this question, a "car" has a combustion engine. Regardless of make or model I can almost always recognise the sound of a car backing up. This sound is distictly different from when the car moves foreward and the difference in sound seems to be the same for all cars.

Is it the gearbox? The transfer? The differensial? The engine runs the same way regardless, so it shouldn't be that, right?

Sound of silence My daughter dived underwater in the swimming pool and screamed as loud as she could. I was right next to her with my head out of the water, but I could only detect the tiniest sound, at the end of the scream. But when I was underwater with her, I could hear most of the scream. Why?
