Well just as the high SPL bass can damage your ears even if you can't hear it, the high luminosity light could damage your eyes even if it is too bright for you to see.

 

Mind you, you probably would see it as it would most likely be a start producing a very complex amount of colours. So just as you hear some of the bass, but not the one you are hoping to see, you would see some of the light, but not the most harmful ones.

The woes of being human and flawed. Then again, what fun would music be if we were osciloscopes.

sub sonic is sound that travels Slower than the speed of sound.  700mph-750 is generally the speed of sound

Sound that travels slower than the speed of sound?

 

How is it sound then?

 

Didn't know sound had a special olympics teams

 

anyways I will stop here because I don't want to look like I am trolling you, but you can always preview your posts before submitting them!  ;)

Im sorry, Im just a kid trying to learn hehhe!. But it would make sense that Sub sonic Frequencies Are sound waves that travel sub sonicly. Which from what i know means below sonic frequencies, meaning slower? Well anyhow. You have good points  no trolling! we are all learning here, and our discussion is good info.!

I laughed a bit harder that I should have at that...

why would they call them subsonic if people could hear them?

 

"Sound" is a human perception... they are just waves like any other.

 

Sound is the range humans can hear, just as light is the range humans can see. (well ok it has to be vibrating air for us to hear so not EXACTLY the same)

 

but it is the same with colours, infrared is below what we can see, and ultraviolet is above what we can see..... subsonic, ultrasonic..

 

Saying you can hear subsonic frequencies is like telling me you can see infrared... which you can't. No one can.



I can. Honest.

I am not a physics major, but from what I understand the hz is how quickly the wave oscillates, not how quickly the wave actually moves.

 

I am sure there are technicalities I am unaware of, but for all intents and purposes all sound moves at the same speed away from the speaker, but the waves vibrate at different amount of times per second.

 

So bass is "slower" in the sense it is less cycles per second, but the low hz wave emitted is traveling to your ears just as fast as the mid range or treble.

 

From the very definition I would suspect there is no sound that travels lower than the speed of sound, otherwise it would be wrong right?

 

That's like having a highway in which you can legally go 60-100 km/h but you are not ticketed for going 45 kh/m.

 

 

 

You might find the "brown note" episode of Mythbusters interesting... they play 5hz or something insane like that at 160 dB (which would rupture your hearing instantaneously) but all you can hear in the recoding is the mechanical sound of the subwoofers themselves. You have to understand that when a wave is played, it is seldom that wave on its own.

 

Check the measurements of the harmonic distortion for headphones. Playing a 1khz wave through them never produces a pure 1000hz wave.

Correct wink.gif The only thing that slows down sound is interference, for e.g. Traveling through different materials - Refraction happens, the sound waves have to bend due to the change in speed etc. Blah blah blah.

God I listened in my A level Physics. Ha.

Interesting. interesting.  my understanding of a HZ The wave length and time it takes to make that wave.  For instance Lower frequency Sounds better Farther away, because the full wave length can be created.  If Loud enough a subwoofer in a big Room playing 30hz will sound better 30feet away then right up close. I think i just got off topic but more information for us!

Well I am interested in the driver technology for the XB 1000 that is for sure.

 

Sennheiser had to make their driver a ring (driver with the hole chopped out) to get to 56 mm or whatever it is in the HD 800 without sacrificing SQ at any frequency. I wonder if the XB 1000 harbours similar technology or the magicians at sony found another way to do it via strong ass magnets or something.

 

and I do realize we are talking 120$ vs 1400$

Yeah Senn chopped a hole out because the center material of the diaphragm was probably lagging IE Distorting. or possibly too much bass.  I would thing  with that hole in the middle the could put a small tweeter and use the Ring As a woofer? I don't know why Headphone company don't use dual driver technology. or try

Getting really off topic here but yeah it was because it was too slow for high frequencies.

 

A number of companies have done multi driver units in the past, namely akg.

 

Multi driver units are largely unnecessary in headphones though. I mean any recent flagship headphone is able to reach down relatively flat until 20hz which is all one really needs.

 

 

When people eventually get these I suggest using "Jenova Project" by Datsik as a benchmark.

Or Soma by Deadmau5 if you can't stand that awkward dubstep beat
