PS Audio Noise Harvester

Still, you have to admit ES hasn't yet achieved the status of kleinman. That guy's got a 3500+-post-thread going on evilution.

ETA: Reminds me irresistibly of the cartoon of the guy with the large ding in the front wheel of his bicycle: "For such a small dog, he was amazingly persistent."

Then you couldn't breath, daaaaaaaaaaaaaaaaa, there is not enough dust in the normal air to do anything.........daaaaaaaaaaaaa. And also what is your proof that sound will not go thru the air, obvious is not an answer, testing is.

So you numbers where that low...........:boggled:

My IQ numbers were low, very low, but still twice as big as yours.
 
whats the purpose of continue to answer to this thread? entertainment? there are far more interested threads around...
 
For anybody interested in some real engineering:

I’m presently building a small audio system. The plan is to have two small two-way speakers to cover 80Hz-20kHz and a sub-woofer for 30-80Hz. Each drive unit will be driven via a separate power amplifier (probably LM4765) and have the crossover and equalization implemented via an FIR filter in an FPGA. I’m considering using negative output impedance for the low frequency drivers in the stereo speakers to provide some motional feedback. To reduce distortion from the sub-woofer I’m planning to use accelerometers to sense the movement of the speaker cones.

Audio is one of those fields where even quite sensible people will spend hundreds or thousands on fancy electronics, then feed the output into a mechanical transducer with no feedback to compensate for its grossly non-linear response, relative to the electronics driving it. I’m always amazed when audiophiles claim to hear the difference between electronics that have 0.01% THD and 0.0000000000001% THD, while using speakers that have a THD of 1-10% and a frequency response all over the place.

True intelligence cannot be measured in numbers.

IQ tests are as flawed as the tests skeptics use to measure the Noise Harvester.

Considering your next statement - I take it your I take it your IQ is scored in irrational numbers?

If you put enough dust into the air the soundwaves can't pass through anymore. It's pretty obvious.

Yeesssss..... many a seismologist could attest to that....:boggled:

Or they hear differences between wire, and when they put BS paper on already shielded equipment.

Skeptics listen to their music with the speakers in the basement on max volume because they don't know any better. They think that just because the soundwaves reach the top of the house it's good enough.

It is better to remove as much as possible between the speakers and ears to get the least distortion.

Bogus and bogus..........

There's a half-truth in there somewhere, though. Different frequencies of sound do attenuate differently due to distance, angle, and physical barriers.

Visible light has similar issues with frequency, which is why distant mountains can appear in beautiful subtle shades of blue or purple. (No doubt ES would insist on a camera that would faithfully image their "true" dark green or brown colors.)

Making sound "perfect" by divorcing it from the physical reality of its surroundings seems a sad and feckless pursuit, like making poetry "perfect" by replacing the distracting, imperfect meanings of words with pure pristine gibberish instead. ES, have you ever made music by vibrating a taut string with a bow, or beating a daiko drum, or just taking a deep breath and belting out a song? Or are you too afraid of producing imperfect audio?

Perfection of the type you're seeking is easy: set a lab standard sine wave generator to 256 Hz and connect it directly to your headphones. There's perfect sound, that you can listen to all day. But it's not very interesting. If you want something worth listening to, you need sound that has something to do with the real world.

Yes - we all do that... and make sure our sub-woofers are parallel to any leylines as well.

I think this thread has demonstrated quite enough has been removed from between the ears.
 
The two major problems with headsets are, that bass is very much influenced by how they are placed over the ear or in the ear depending on the design (which has nothing to do with paper) and they also give stereo channels an exaggerated separation.
