By very careful control of the frequency, phase and position of the speakers. It is quite easy for a single frequency, more complicated for complex sounds. But this is how noise-cancelling headphones work (in the small space inside the headphones).

That is has some wave-like characteristics and some properties we usually associated with particles.

Why would that need to be relative to anything? You can take a single photon or electron and measure its wavelength (a wave-like property) or the point it its a screen (a particle-like property).

Is it both, wave and particle, at the same time. Or is it more like, a wave for a certain percentage of time, and particle for another percentage of the same given measure? Or is it more like a wave that is cancelled relative to "like" waves, and harmonized relative to other "like" waves, and not relative at all to other like wave/particles existing in positions less relative within the quantum field?

Is this effect position relative, instant to instant? (instant being equal to the time it takes to travel one plank length at the speed of light.)

Also: In notes of frequency, let's say the musical note E for simplicity. Would a lower E note cancel a higher octave to some degree, while harmonizing with it at the same time to some degree? Is this what makes a tuning fork vibrate?

None of the above. They just happen to have some properties that we usually associate with waves and some properties that we usually associate with particles. They are neither waves nor particles.

No. Notes that are very close together will go in and out of phase causing a recognizable "beating" effect. This can be used for fine tuning of a guitar for instance.

Is this what makes a tuning fork vibrate?

No. Hitting it is what causes a tuning fork to vibrate.

So, the electron wave is absorbed by the plate, giving it's electromagnetic bonds a little boost and then the excess energy is radiated as photons of light at a point of least resistance. Like a free electron powered flashlight.

But the wave function collapses when we observe it. Think we could use this device to measure the gravity of our own thoughts? That would be weird, even by my standards, lol.
