Am I insane for worrying about this?

Think yourself lucky it's 20Hz

The brown noise

If the human body is subjected to low-frequency sound waves (between 10.5 and 16 Hz), there is often an uncontrollable and instant urge to defecate. While the use of this \'brown noise\' has been investigated for military and crowd control uses.

Emerson Lake and Powell maybe

And believe it or not you are continually surronded by this kind of frecuencies (that bus passing by, for example), you just don't feel them (unless they have enough amplitude as to be detected by touch receptors) and I think nobody dies because of that... although on a second thought, because all of us will sooner or later die... that might be the cause!!! So don't worry, but don't buy a record with inaudible "sounds", that's nonsense...

It's not an album of inaudibileness but it occasionally uses these sounds.  I didn't hear about this possible death frequency until after the purchase on amazon.com  And thank you all for not outright calling me an insane paranoid person that is ignorant or something.

Ah! Gaston!

Maybe you shouldn't listen to the record in the mountains!

It might interest you (and maybe calm your nerves) to know that it is those exact ultra-low frequencies - low rumbles and subliminal sounds - that are often used in movie soundtracks (especially horror/slasher films) to cause feelings of anxiety.  However, I don't know of anyone who has died after watching one of those films.  It is simply an immediate - but temporary - response to a sonic stimuli. 

Still, if I knew that something was going to cause those types of "anxious" feelings, I would probably not deliberately subject myself to them.

Peace.

You obviously haven't heard Britney Spears.

What a coincidence! I happen to have a collection of masterpieces recorded in the freqencies usually reserved for bat calls and dog whistles. Because of the frequency limitations of the human ear- not to mention the even more limited range of existing recording formats- it sounds very much like a blank CD. But take my word for it, they're masterpieces- and will not cause any medical problems, unless inserted into a body cavity. Only $49.99 + S&H for the whole collection!
