Hi Pete,

You're being serenaded by hundreds of switching power supplies and 
microprocessors. If they drift, they're SMPS. If they don't, they're 
from a microprocessor. I'd take a WAG that the average residence has at 
least 30 such noise sources. Virtually every wall wart, battery charger, 
PS for low voltage lighting, computer, computer accessory, variable 
speed motor controller, etc. is an SMPS.
