Filtering out the buzzing noise during World Cup games
- Thread starter nd2023

Tell more info....is this on a TV, radio, or what?
Continuous, or varying?
If it's on a digital TV signal going into a converter to an older NTSC TV, the signal may have so much contrast that it's unavoidable.
The contrast ratio sometimes can be turned down on the TV, or see if the TV permits some kind of fine tuning on the analog channel, which can also help.

It's in the stadium. It's the tens of thousands of fans blowing horns.

We used to get complaints about the same sort of noise during golf. It was just the ambient background noise from air movement, people quietly talking (this was golf, remember?), even the sounds of insects in those hot, humid coastal states.
Probably lots of noises bouncing around in a soccer stadium.

I'm not into Futbol, but I did check it out for a few minutes yesterday and it did sound like a hive of bees in the audio. This is a very new Sony Bravia receiving HD on Comcast cable into a Yamaha surround amp with Klipsch speakers.
Correct, the horns are called Vuvuzela's: http://en.wikipedia.org/wiki/Vuvuzela and yes, they ARE a pain in the eh... behind! ;-)DavidEduardo said:
Boy. I wish they'd filter it or something. I might watch a little more as it heats up but the buzz is really annoying, and no I don't want to watch with the sound off.
Yes, you can filter it. If I get time to build a digital filter this week, I'll have it ready for Friday's USA vs ... whoever we play ... game. A nice little notch filter at 233 and 466 Hz should help a lot.

Or better yet...just don't watch it. Soccer isn't worth the trouble really.

Think "horn" as in "French Horn." The stadium horns are essentially the same concept, but with no keys.

That would be why it has more fans than Baseball and (American) Football combined.

Soccer is a great game for kids but played at the professional level it is a defensive struggle and usually quite uninteresting.
As for the buzzing.....heard this afternoon that the head of FIFA (governing board of soccer) will not ban the instruments but ESPN says it will turn down the stadium volume.
I'm not sure that makes much difference as the British announcer the past two games almost puts the viewer to sleep and his Scottish 'color' guy is apparently speaking a foreign language (Scottish English). Turning off the sound will improve your enjoyment of the game.

That's unfortunate. I didn't record anything last weekend, not expecting to hear an annoying buzz. I had no idea what a vuvuzela was at this time last week, or really at this time yesterday. I just know that after hearing them continuously for a 45-minute half of soccer, I was thankful when the commercials came on.

Except here in the United States. And that is where our discussion is taking place, correct?
You want to play a real man's game, strap on a set of pads and go against the Steeler's d-line. You want to watch a bunch of people run around kicking a ball, head down to your local elementary school playground.
I well recall 1972 at a summer camp for 2 weeks, when a soccer field was laid out in a huge mowed grassy field, and the game rules were explained to us. After 30 minutes of what seemed to us like a lot of useless running around, the counselors gave up on trying to convince us it could be fun. Later in the week when I became involoved in "youthful disagreements" and strife,
a boxing ring (on the ground) was set up, where REAL sport could take place....you guys wanna disagree, here's your boxing gloves, here's the rules. Go at it. And it was a lot of fun and went on for several days.
To this day, I still prefer competing against myself for best when possible, but if I am to choose sports in order of appeal,
it would be windsurfing, surfing, drag racing, roller derby, then baseball and US football.
Every day ( and night ) I have only to look out the front window of the house to see soccer in the park across the street, and as my neighborhood looks like a UN convention, I accept this, but it still does nothing for me. I was in Mexico whatever year it was they won over Italy (or was it Argentina?) and I remember how all work stopped at the factory to watch the games.
Why is it that some nationalities think yelling (by players) during a match is acceptable, while others look down on this?
I know why I'd rather they not holler, but I'm wondering why those who don't yell all the time have this preference.
Is it considered low-class or what?
Back to the buzz, I tried some more, but it seems hard to filter because there is no phase reference...it's not one vuvuzela, but 10s of thousands, so an active filter can't find any particular "point" to reference.
A passive filter might work, if designed at into a low-impedance circuit, as in the speaker path, but gosh, what an amount of wire
on an air-core would be needed to cut that low!.... I've hand wound notches for 10 khz and 5 khz, but it would be quite a bit for these lower tones, and also would be needed one for each of the overtones.

Australian rules football. Enough said.

I think much has to do with exposure to different spórts while young. I played soccer as a kid, and was a pretty good goal keeper; my basketball, football and baseball skill sucked. So guess what I like now?
A friend in high school who had not seen more than a couple of American Football games told me he could not understand why a bunch of guys stood around for minutes on end, and then bent over and jumped on top of each other without being embarrased. Lack of exposure!
Neal Boortz was saying today that someone has Written a software filter for that noise. Don't Know the details, but who cares it is only soccer. Imported into the US so the moms can let thier sons play a sport without getting an owie. I agree to put pads and gear on and turn them into men! Football is a sport, soccer is wussy.
