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.
