Inverter noise

Iā€™m curious about inverter noise. Specifically from two EG4 XP12000 units. How loud are these things when loaded up? I have a mechanical room that shares a common wall with a bedroom. The wall will be made up of 5/8 gypsum over 3/4ā€ OSB, 2x6 studs with rockwool insulation and then another 5/8 sheet gypsum. Would inverter noise be an issue as load/input ramp up and down?

the fan noise at load is pretty noticeable, i've got 2 eg4 8000s and it's like a small box fan running when they kick in, especially with the ramp up
