Background hum: For Europeans who come to the US - do you notice a difference in the hum produced by electrical equipment? Because you may be used to fans, transformers, etc. running at 50Hz vs. 60 Hz in the US, and that's in the audible range.
- snowwindwaves 9y agoI was a co-op student at nortel networks in the 90's. They had an anechoic chamber used for testing telephones. I remember the lightbulb hanging from the cieling sounded like a swarm of bees.

Unless I consciously pay attention, I don't notice it either, maybe just watching to many Holywood movies, maybe there is a difference between movies and reality.
