If you have to stick with Mega2560 and Ramps, you can try to use a separate 24V or 36V powersupply for the stepper drivers only. That made a huge difference for my TMC2100, but it really got silent with 32bit controller ( RADDS and RRFirmware)

But I can't understand difference with mega2560 and 32-bit controller with the same stepper driver and only 80steps per mm.
The 8bit MPU is able to produce the step-pulses fast enough, but they are not evenly spread. That's why they are noisier.

The 12V power supply can also be a problem, because stepper motors are controlled with a constant current.
So at higher speeds the current can not be reached with a 12V power supply, please try a 24V one.

On high frequencies the Skin effect is working, so the resistance of the motor coils are high and you need more voltage to reach this current.

It would be helpful to know what motors were used by @abuharsky and @kolin. They may have been low current high inductance motors, which are not suitable for operation with a 12V supply anyway. Hint: if a bipolar motor has "Rated voltage: 12V" in the specification, then it is NOT suitable for use in a 3D printer with 12V power, because much more than 12V will be needed to reach sensible speeds.
