		<description><![CDATA[I read quite a few “experts” here with the absolute, unequivocal statement that nobody can hear about 20KHz. First, the human ear is an analog system. There is no 20KHz “cutoff” beyond which nobody can hear. Everyone has a curve of decreasing perception and some point where the curve falls below the level of perception. The 20Khz frequency cited was chosen for two reasons: 
1) the vast majority of people cannot hear anything above that frequency (note that I did not say all) and 
2) it’s a nice round number. ...]]></description>

		<description><![CDATA[A proper hearing test can help determine any hearing loss you may have by measuring your ability to differentiate and respond to a series of tones in a controlled sound environment. Take our new and still unscientific hearing test.

Try using a good pair of headphones in a silent room. The mp3 sound files have been replaced with wav files for greater frequency reproduction. Also, the tones now range from 20hz to 20kHz. Post comments about your results or vote to record and view hearing loss test results. Depending on your ...]]></description>

		<description><![CDATA[Matt here again. I took an mp3 listening test here a while ago. The shoot out was between an mp3 of 320kb/s vs. and mp3 of 128kb/s. A number of people commented that a test between a pure wav. file against a 320kb/s mp3 would be more useful.

So I went into my vault and pulled out a 24bit wav file with plenty of harmonic content &#8211; all sorts of broadband sound just begging to be handled with kid gloves. Then I shot it through my iTunes mp3 encoder and yanked ...]]></description>

		<description><![CDATA[Ever wondered about hearing voices in your head? I’m sure that’s exactly what the military was aiming for when they originally started project MEDUSA or Mob Excess Deterrent Using Silent Audio. The original “telepathic ray gun” works by sending a weak microwave into someone&#8217;s head, emitting noises only the person in the wave&#8217;s path can hear. 
Here is a concept diagram of how the microwave audio device might work.

The number one risk preventing the MEDUSA project&#8217;s success is not radiation (as some might believe). It’s actually the risk of brain ...]]></description>

		<description><![CDATA[Many people worry about their computers being hacked. Very few worry about eavesdropping used on their printers. In the May 2009 issue of Scientific American, an article talks about potential office hacks using surveillance tactics, one being recording and analyzing the sounds made by a printer. So far, the research has been done on dot-matrix printers. These are the old noisy kind; however, they are also still in commercial use by industries like airlines, banks, and hospitals (each of which prints sensitive information).  
Dot-matrix printers create dots on a piece ...]]></description>

		<description><![CDATA[Take a listen to this audio clip. Be Careful, the sound (if you can hear like a teenager) is loud and annoying (it&#8217;s not called a mosquito ringtone for nothing). You may want to turn down your computer speakers and turn up gradually to test a comfortable sound level.
What do you hear?  If you don&#8217;t hear anything, you&#8217;re not alone.. and you&#8217;re probably over the age of 25. If you can hear it, then you likely find it fairly annoying.

		<description><![CDATA[ Mari Kimura is a New York composer and virtuoso violinist whose music includes haunting low notes on the violin called  “subharmonics.”  &#8230;Problem is, these sounds aren&#8217;t supposed to be possible.
 The tones she playes are in the register of a cello, and usually cannot be made from a violin.  Even she is stumped about how it works.  “I don’t really know what it is I do,” she said, because she learned it by “trial and error.”
A team of scientists in Norway, is the latest to take a crack at the puzzle.  ...]]></description>

The Vegetable Orchestra performs on instruments made of fresh vegetables. 
The utilization of various ever refined vegetable instruments creates a musically and aesthetically unique sound universe. The Vegetable Orchestra was founded in 1998. It consists of 11 musicians, a sound engineer and a video artist. Based in Vienna, the Vegetable Orchestra plays concerts in Europe and Asia. From time to time workshops are given &#8211; on how to manufacture an instrument or on musical topics.
