3D Soundwave Interaction Visualization

Job ID: 38728452

Budget: €30 – €250 EUR

I'd like to visualize the behavior, that occurs when two soundwaves expand next to each other. Given the sources of said soundwaves originate with a distance of maybe 20 centimeters/9 inches.
Imagine a piano, in which strings are hit when you play. The strings vibrate, producing a sound that travels outwards in a spherule shape. Hitting two keys simultaneously, which strings are the given distance apart, produces two soundwaves which spheres overlap - in some cases producing a harmony.
I'd like to visualize the process of two soundwaves expanding next to each other, overlapping. No piano or instrument is necessary. Just two spheres in an otherwise empty space. For education purposes, the spheres should've different colors, so one can tell which part of which sphere interacts in which way.
The animation should follow the laws of physics. There is water animation, that shows what happens if you drop two stones next to each other in a watery surface/liquid. Imagine this, but only in 3D.

I'm not sure if this is possible in the first place, but given that there are water animation packs in software like blender, I thought this could be applied to more than just a 2D plane.

The visualization should be simple and easy to understand, showing the basic interaction between the soundwaves.
The animation should be less than 30 seconds long.
The final deliverable should be in a video file format.
The visualization should exhibit a high level of realism, emphasizing detailed physics-based interactions and accurate wave behavior.
The visualization should have a stylized look.
The background should be transparent for a cleaner look.
The visualization should achieve a balanced level of realism, enough to accurately convey the behavior of soundwaves.
The video should be rendered at 30 frames per second.
Please use Blender or a similar software to create the visualization. The visualization should be created in an illustrative style.
