Research & Development. - Psychoacoustic's

[TheBandwagonman]

Not true. Your ear has a threshold to the particles hitting your eardrum. If you were in an anechoic chamber, and had earplugs in, the only thing you would hear would be psychoacoustical sounds, and sounds physically generated by your body.i e. blood flow heartbeat etc.

As far as I know, when the brain is deprived of input such as sound in an anechoic chamber, it begins to produce it's own input. i.e. the ringing in the girls ears

[Kramkat]

The ringing in their ears that both girls experienced....is this a common occurrence? and if so, what is it they're hearing, is it the nervous system you can hear? blood flow? 

Curious.

@Kramkat tinnitus, a small form of it but that'd be it, most people have some sort of it, it's just that if you're not in a room that is as quiet as an anechoic chamber you're not going to hear it.

What kind of video effect is used here? Moves looks cool in high speed.

[angeldustpro1]

camera is all that matters here.. They used a very high quality camera with a lot of frames per second...

Frames per second is all that matters to achieve this detailed movement in high speed forwarding... ;)

[realitas]

@angeldustpro1 Not so...high framerate is important for low speed playback, not high speed playback. At high speed most of the frames are discarded.

Can you show whole video in regular speed? Would like to hear what they were talking about and their reactions while being inside.
