Question about electricity used by speakers and electromagnetic field.

[Thor_Sevan]

Hi !

I just wondered... if I am able to have these Klipsch promedia speakers (big IF !!).. that are 400 watts... it won't use 400 watts all the time right ? While playing games at 20 % volume it is supposed to use 20 % of 400 watts ?

And having a big crazy sub of 180 watts near my bedroom... isn't that dangerous for my brain ?!?!?!?! 🙂 hehe... I mean...that would mean 10 hours a day my head near two big crazy sub speakers... humm.. dono... 🙂

What do you think ? 😉

The speakers should be shielded.

 

[Thor_Sevan]

Is the sub shielded too ?

All that crap about magnetism and cancer is BS. The big advocate of that movement was found to have falsified his data when he found it didn't confirm his theory. All the greenies that were sucked in by him don't have the principles that it takes to admit you have been fooled. There have been a couple of articles in Scientific American Magazine and similar publications describing the hoax but like all that stuff it seems to have a life of its own. For now, there is no credible evidence that establishes a link between electromagnet radiation at low levels and physiological effects of any kind.

yeah I know... but maybe it has an effect but its not really important. If we consider that our body blood cells contain iron.. maybe they are attracted by the magnet and not going where they were supposed to go... 🙂 hehe

You should just keep your speakers off whenever you aren't using them. That will save power and your blood cells if you think magnetism does anything to them

There is no strong direct correlation between EMF and cancer. Not surprising, as the level of EMF talked about is non-ionizing -- that is, it cannot directly break any molecules in your cells, which is thought to lead to cancer.

Having said that, there still may be an indirect effect. For example, there is a theory that EMFs can reduce the pineal gland's production of melatonin, which in turn is theorized to prevent cancer. Two big assumptions there though. Another theory is that while EMF's might not directly break chemical bonds, it can shake them up, creating heat (that is how a microwave works btw -- it uses the exact frequency needed to resonate the hydrogen bonds in water, creating heat) and this heat can somehow lead to physical changes.

Having had cancer (Hodgkins) I think this is all BS, but hey, you never know. Far as anyone knows, cancer is largely genetic, but is triggered by something environmental. In my case, it was probably a virus (Epstein Barr is the best guess so far in the field) and my bad genes (lots of ppl in my family had cancer, including Hodgkins).
