bluetooth operates on the 2.4Ghz spectrum. It overlaps the WiFi signal base frequency except WiFi is stronger.
Just a smidge lower on the frequency is XM Satellites which are Geosynchronous... they are constantly plastering North America with those frequencies 24/7.
Just slightly down on the frequency from there is GPS.
Lets also no forget cell phone signals
RF from lots of electronics to include cars.
FM/AM Transmitters
TV broadcasts
So unless you live in a faraday cage with no electronics of any sort (Amish and even then, they have cell phones), you are getting a constant dose of Electro-magnetic frequencies from audible all the way to cosmic on the daily.
When your number is up, it is up.
