Or "watts around 2.50 GHz" . . . so where are the EMI 'Karens': Prius - where I first heard their whining EVs and Tesla - where they moved on to Microwaves - <crickets> The rule is if something is too expensive or rare, the 'Karens' are there. But if you need a bag of popcorn, silence is golden. Bob Wilson
I remember selling full copper core spark plug wire sets to shade tree car modifiers. They always wondered why their radio/stereo wasn't working properly. The auto parts store also had a nice line of stereo equipment too
There are other EM sources in most electronics to consider, but I wonder how many of them produce any appreciable power at wavelengths short enough to go through an oven mesh, without being designed to do so.
People around here often hold their cell phones away while talking. Get me sum ma that one over r squared! Do they, elsewhere?
Just at the local bars where the cell phone is on speaker and caller is shouting back. I liked them better in the 1970s when they stood on street corners and talked to someone in the North 40 acres. Ah for the days of 'Hari Krisna!' Bob Wilson
I get it! Local bars....... I use airpods to listen to audiobooks, podcasts, etc and they also work remarkably well for phone calls. I use a soft 'stage whisper' with a hand cupped over my dominant ear when I'm in a store and asking my CFO if I got the right brand of whatever - or I just use a photo and text. I only use my speaker in my office while actually on hold and listening to the torturous looped messages informing me that my call is VERY important and to please stand by!!!! ....for a VERY LONG time!
LOL! Old school, I used wired ear pods with a good seal and the last pair were noise cancelling. I have no idea what Apple was thinking about with those non-sealing thingies. But since I read about 2x-3x faster than most media, I'm web surfing at my favorite forums, like here. I prefer to watch media playback at 1.25-2.0 speed faster. I was surprised at one of my local bar and restaurants when a young lady sitting near me was making somewhat 'riskee' comments to other patrons. The owner whom I've known for a decade chatted with his bar staff and then asked her to leave. I had never witnessed that before except with falling down drunks. Bob Wilson
The Apple Pro buds have fairly decent ear seals - at least decent enough for lawnmower ops. Their noise canx is about as good as any other in-the-ear appliances but you're going to want over-the-ear for REAL isolation.
While I was in high school, the Girl Next Door™ moved away, to sunny SoCal. But I did hear from her a couple years later when she was back in town for a visit. We picked a time and one of the local bars to hang out and catch up. Well, the door to the bar opens and this tall, transformed, SoCal blonde bombshell walks in. There are, like, audible indrawn breaths and murmurs of amazement from other bar patrons. She looks around the place for a second and then walks over and gives me a hug. There are audible groans. 'nother bar story. I had a gig during college implementing a PDP-11-based fire alarm system for a local hospital. I was quartered with the physical facilities staff, who would typically end the workday with a visit to Tom's Tavern. Tom's Tavern had been around a long time. I mentioned it to my dad and he remembered going there. It was still run by Tom, a not-very-tall but sort of Popeye-shaped Greek fellow. The place was small and bare bones. Tom would serve drinks from an ice cooler behind the bar. At times he would be away briefly for some reason, say to go down the street for the newspaper, and when that happened some regular patron or other would slip behind the bar to cover for him. (I'm not sure how this comported with state regulations, but that was how it worked.) One member of our party from the hospital was a tall, red-haired woman, rather magnificent. Three of us came in one day and sat down at a four-top, and hardly sooner had we sat down than a guy on the street looks in the doorway, comes in, walks straight to our table, sits in the fourth chair, and starts talking to her. Tom shuffles over from the bar, points to an empty table, and says "You. Go sit over there."
Nice squal line passed through: Well the high winds proof tested the solar panels. Automatic generator ran at least twice, I was sleeping. Blew down privacy fence and rolled a metal shed. Bob Wilson
