have a noise problem.

I have these devices to supply:

Magma Chassis: 12V
Laptop: 16V
Wireless headphones emisor: 12V
Portable preamp/AD: 6- 14V

I thought about using a 12V to 16V converter to the laptop, and so woul have all devices conected to 12V, and so could easily use the car battery, or AC using a 220V-12V psu.
The problem is that using the 12 to 16 V for the laptop, a high noise from the laptop enters in the other devices, especially the wireless emisor.
I would like to know if it could be isolated diferent the diferent devices to avoid noise between them.
I suppose I would must to filter, but would be enough?
The other solution, could be use the 220-16V for the laptop. But then to use with the car, would need an inverter. Would this option have more comsumption?
What do you recomend?
