Hello,
I've been tired lately with the amount of acoustic noise coming from the Wall Wart Switching PSU's in my house.
The noise normally is an High Pitch frequency around 10Khz,
I have it coming from my iphone charger, ipad charger, Router Wall Wart, a misc wall warts for equipment.
The only thing in common is they're all switching power supplies.
A lot of people don't notice it, but as we deal with audio we are much more susceptible with those high pitch noises.
Is there any way to modify Switch mode power supplies Wall Warts to reduce or even get rid of the 10Khz acoustic noise?
Thank you
