Subject: FLICKER 2.0&lt;P>FLICKER 2.0&lt;P>Goal:&lt;BR>
Brainwave spectrum emmitted while watching flicker translated into sound.&lt;P>Set-up:&lt;BR>
test subject-asian american female&lt;BR>
IBVA&lt;BR>
Madrid flicker video sample&lt;BR>
MAX interface&lt;BR>
SuperCollider to emulate sounds using algorithmic functions&lt;P>*Test A&lt;BR>
emulation of spectrum detected by volume level changes in pink noise&lt;P>Result:&lt;BR>
- -slight building of pressure in head&lt;BR>
- -very slight nausea&lt;BR>
- -changes in noise level in sync with horizontal lines moving across the screen&lt;P>*Test B&lt;BR>
set pitch to follow the dominant frequency of spectrum&lt;P>Result:&lt;BR>
- -pitch changes with frequency of eye movements&lt;BR>
- -little change in sound&lt;P>*Test C&lt;BR>
set beat to follow dominant frequency without eye movement.  set ground&lt;BR>
frequency to constant of 200 hz. Beat frequency 200 - 460 hz.&lt;P>Note*change in test subject to australian male*&lt;P>- -subject fell asleep&lt;BR>
- -little to no brainwave activity&lt;BR>
- -little change in sound&lt;P>Conclusion:&lt;BR>
Changes in frequency levels too slight to create dynamic sound range.&lt;BR>
Increase in activity of observer may create sufficient levels for more&lt;BR>
interesting sounds results.&lt;P>&lt;P>&lt;BR>
