The Quietest Place on Earth

I can&#x27;t confirm that these are the same, because I can&#x27;t access this site. However, I suspect that this is the same as has been reported from many source, and submitted many times.

Why would Companies use a chamber with a background noise of -9.4 dB to &quot;to test the sound levels of products, such as washing machines, refrigerators and Harley Davidson motorcycles.&quot;<p>I would think any half decent noise chamber would do the job.

Oh wow, and here I was thinking it would be a tie between the Google and Facebook customer service centers.

there is a chamber like this at my local university that I have been in a couple of times. its very strange to talk or hear others talk. your voice just feels weak. even when you yell the sound just stops... yet, ears seem to adjust the percieved loudness of things relative to the background, and in a chamber like this you ask your ears to divide by zero, and sometimes it feels like even the silence is louder than anything you have ever heard.

I am guessing someone who is deaf could win at the challenge.<p>I have spent time in Anechoic chambers for doing noise level and vibration testing on equipment. They are disconcerting for sure, but I have to imagine someone who never hears anything would not be disoriented.<p>The shape of the walls messes with me I think more than the sound. We aren&#x27;t used to not having flat surfaces to judge distance against and not having anything that is only &quot;one&quot; distance away definitely works the part of the brain that does depth perception.

As per Wikipedia [0], The Acoustics Department at University of Salford has a number of Anechoic chambers, of which one is unofficially the quietest in the world with a measurement of −12.4 dBA.<p>[0] <a href="http://en.wikipedia.org/wiki/Anechoic_chamber" rel="nofollow">http:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Anechoic_chamber</a>

I propose a vacuum chamber as a better candidate for the title of the quietest place on earth.

Can someone summarise? Once again, as a Brit I&#x27;m unable to access content from BBC.com.<p>Thanks :-)

Beyond hearing your own heartbeat after a while, an ultimate psycho-acoustic experiment: hearing air molecules hit your eardrums.<p>Taken from Master Handbook of Acoustics 5th edition (page 39-40): The human ear cannot detect sounds softer than the motion of air particles on the eardrum. This is the threshold of hearing. There would be no reason to have ears more sensitive, because any lower-level sound would be drowned by the air-particle noise. This means that the ultimate sensitivity of our hearing just matches the softest sounds possible in an air medium.

Wait, is the 45 minute thing true?<p>Is there any way I can volunteer for an attempt?

We have exactly the same room in our Physisc Department, in Poznan, Poland. We call it &quot;noecho room&quot;. <a href="http://www.ia.amu.edu.pl/index.php?option=com_content&amp;view=article&amp;id=5&amp;Itemid=9" rel="nofollow">http:&#x2F;&#x2F;www.ia.amu.edu.pl&#x2F;index.php?option=com_content&amp;view=a...</a> Greeting from PL!

I&#x27;m envious of those who could hear their own heart beat. I suffer from tinnitus, and when things get quiet all I hear is a thin high pitched ringing noise.

I don&#x27;t understand the challenge part. Why don&#x27;t people with bad hearing go nuts in normal quiet rooms if not hearing anything is so challenging?

&gt;won&#x27;t come cheap<p>&gt;$300-$400&#x2F;hour<p>That doesn&#x27;t sound too bad actually, I expected an order of magnitude more.

&quot;-9.4 decibels&quot;<p>erm, decibel <i>what</i> exactly? Decibel is a ratio between two values. If you don&#x27;t state the one compared with, you&#x27;re talking pretty much nonsense.
