Okay, perhaps there are a few audio engineers out there or Sherlock Holmes types that can solve the mystery of WHY when the (unseen) Capitol Police in the video below are shouting into their communications devices we can hear NO background noise at all despite the fact they were supposedly in the middle of a riot?
Well, if there’s anyone here who’s an expert in ‘nonsense arguments’ it’s a moron like yourself.
Who’s ‘he’ champ? The OP posted a video of SCORES of clips. Which clip are you talking about? What’s ‘the time-stamp?
Also one of the protestors they featured was also speaking on the radio in which there was no background sound at all.
K.
There was no riot.
They panicked at the thought of actually having to work and get off break and help guide the tourists between the velvet ropes.
The filtering takes place on the receiving end for certain devices...ie electronic earmuffs.
Police handhelds, the mic and speaker are in one unit. Take a look at the next cop you see and they have a cord from their radio to the mic/speaker that is clipped to their shoulder or chest. It’s all in one.
Two different things.
Go to a gun range and use ‘noise canceling’ earmuffs. You can have a perfectly clear conversation, hear everything, hear the beep of the timer, once the gun goes off the electronics cancels out the noise.
It’s not possible to have that on a handheld radio with the mic/speaker hanging off your body somewhere.
Not following you.
That is weird, isn’t it?
That isn’t true. The headsets used in airplanes have microphone elements on both sides of the mike boom. The ambient sound reaches both sides of the microphone at the same time; and, is electronically subtracted from each other. The voice of the headset wearer strikes mostly the side close to his face, so is strongly unbalanced with respect to the other side. The voice is not subtracted out.
Exactly what was used.
Guess I better tell my company to stop using the mics that work while I’m standing next to a ten story boiler in a paper mill..? I USE THEM EVERYDAY!!!!!
10-4. The next time you see a cop on the street go up to him and ask him if he has the same comm system that they use in airplanes.
Police radios are what they are. Other than that, I have no idea what you’re talking about.
Police are not required to know the technical attributes of their equipment. If you watched the video at the link, you would have noticed that the equipment he was showing WAS what police and fire-fighters use.
Obviously
ROTFLMAO!
Bye..
I can assure you that the mic he’s holding and talking to, in his garage with no ambient noise, is absolutely not what police handheld radio mics are in 2021.
The standard police handheld is a Motorola xts5000
Nothing like that dinosaur in your link.
As for the noise canceling, again, it takes place as the sounds are caught by the microphone, pass through the software and are filtered into electronic earmuffs/headsets.
Headsets that also have foam, or now fancy silicone gel pads, to conform to a persons head, hats and glasses to provide a seal that also blocks out ambient noise.
When electronic earmuffs cancel out a gunshot, it’s done y boo kit out noises at certain decibels. If you’re at a range and there lots of noise that doesn’t reach the decibel level you hear everything. Gun goes off and you hear nothing.
Try telling that to cops that work loud sporting events or concerts.
Do you have a headset/earmuffs on your comm set up?
Nope. It’s just below the requirement for double hearing protection in all our areas except for the turbine rooms, so earplugs only. No muffs. When I’m in the control room and an operator clicks the mic, there is a split second of noise and then it goes away. Everyone is trained to press the button and say, “and one” in your head before you start talking. Otherwise the first word is usually cut off.
We’ve had these for about two years now. Like I said, pretty expensive. $250.00 a pop.
Exactly the kind of sissy response I’d expect from a queen of your type. You got my full attention now fairy.
