Yes, of course it makes a noise. Sound waves exist independent of their being perceived, as does everything else. When we speak of measurement in quantum mechanics as being fundamental to the collapse of a wavefunction and thus creating relative certainty about a single event as opposed to the various possible events that might have occurred, we are not speaking about perception but of complexity and interaction. Any interaction of sufficient complexity, and it doesn't take much to be sufficient, causes the wavefunction to collapse. A branch of a tree can never be in a quantum superposition between having fallen and not or anything remotely similar. If it falls, it generates sound waves (unless there's no atmosphere, but that's a different question), whether anyone perceives them or not. EDIT: Josh Hulks mentioned Schroedinger's Cat. I've studied it fairly extensively and written on the subject as an undergrad studying the philosophy of physics (I got an A on that paper, actually). The thought experiment was meant to show the ridiculousness of a theory in which perception is paramount. Schroedinger was in no way suggesting that a cat could be in a superposition between dead and alive. Rather, it was a flaw in the standard model that it used language of perception. At the time, there were no concrete theories on what causes collapse. Now there are, though it certainly isn't fully understood, and so quantum physicists don't speak of perception when discussing it anymore. Now it is understood how complexity disentangles wavefunctions. The real open question is whether that process splits the universe into a multiverse of every possibility or whether it is the process by which a single possibility becomes a reality. Either way, it happens without any involvement from life forms.

You need to eat more, make sure you eat three meals a day. By the time you're eating the right amount it should go away. That noise is your stomach trying to digest something but there's nothing there to digest. Hope this helped. :)

You added in "with regards to quantum physics" so I recommend you do some research about a famous thought experiment theorized by Schrodinger called "Schrodinger's cat". The experiment was in contradiction to the Copenhagen interpretation of Quantum mechanics. This will help you solve your "paradox" and gain an understanding about quantum uncertainty and Quantum entanglement.

It is a physical reality it has nothing to do nothing with quantum physics or classical physics.Reason is this that it has been the experience of observer that noise is made and if now observer is not there does not mean that the noise is not made.If events depend upon the observer then Archeology will have no meaning.

You must consult a dictionary for the accepted definitions of noise and sound, etc. Sound energy and noise is produced but there is no one there to hear the sound (required by the definition of sound).

Im so sorry. IT IS NOT PETTY of you. Are there earcovers like people working with heavy equipment wear that you could get? I would leave if you could. Is there any other place you could go? Do you have any money to go somewhere? It is so unfair of those people to do that. I dont think you should threaten to leave because they dont care. It would get you nowhere. Do you have parents you could talk to asking if there is anywhere you could go. They would care about your grades. Do they know an attorney who could write a letter saying the contract is void due to the decibel level? I can see this is stressing you out somuch that you cannot get the benfit of studying. I am so sorry because I am sensitive to noise like you. It s a tough life when you are sensitive to it. These guys are losers and insensitive.
