How to Filter out Vuvuzela’s on your TV

I found this article on my iGoogle today and I find it very amusing. 🙂 Mainly because for the past 4 weeks I’ve been waking up to the sound of vuvuzela’s in the morning (seeing as how I live in one of the cities in South Africa which hosts matches). There is no equalizer in real life, no sound, material or ear plug which can really drown out this noise. 😉 But, WikiHowTo seems to think that they can, so I will give them their dues. 😉

How to Filter the Vuvuzela Noise

from wikiHow – The How to Manual That You Can Edit
When you’re tired of the World Cup broadcast being a cacophony of vuvuzelas, it’s a relief to know that you can tone it down. Here are some ways to drown out the drone.

Steps

Equalizer (EQ) option (TV or Stereo)
The benefit of this option despite having to fiddle a bit more is that you don’t need a computer. You can perform this fix straight on your TV or stereo.

  1. Locate the equalizer. Either use equalizer on your stereo if you’re using that to listen with, or the one on your TV, if it has one. If needed, read the manual accompanying the stereo or TV for instructions on how to adjust the equalizer settings.
  2. Adjust the hardware settings of your equalizer. It is recommended to turn the frequency down as low as your equipment can go; Adam Pash recommends lowering sound level of the the frequencies 235 Hz and 465 Hz with about 40 decibels.[1] The drone sound should be considerably reduced, or even removed.
  3. Continue to adjust the different frequencies until you are comfortable with the sound. Given that all TV sets differ, only you will be the ultimate judge of what works best here. Things to consider include:
    • Level of sound of the commentators’ voices;
    • Ability to enjoy the rest of the atmosphere; and
    • The level of comfort of all persons watching at home.

Adjust Treble or Speakers (TV or Stereo)

  1. If you can’t locate an equalizer on your TV or stereo, or just can’t be bothered fiddling with it, try using your TV’s treble sound control. Locate the treble control, and turn the treble sound down as far as is possible. Doing this should reduce the vuvuzela sound enough to be bearable.[2]
  2. Try adjusting your speakers if you have a surround sound system. Try lowering the volume of the speaker that brings out the crowd noise and raise the volume of the one with the commentator’s voices.[3] Keep adjusting until you get the balance right.

Easy Free Software Option (Computer Assisted)
With this option, you’ll need to use the computer linked up to the audio of the TV. The benefit of this option is that the software will do all of the fiddling for you. The only adjustments that you’ll need to make are dependent on the age and speed of your computer.

  1. Go to the National Instruments site. Download the free software here: http://decibel.ni.com/content/blogs/Simon/2010/06/16/world-cup-2010–filtering-the-annoying-vuvuzela-noise. There is a Windows and a Mac version available, choose whichever one suits your needs.
  2. Install the software. If you don’t have the LabView Run-Time engine, you’ll need to install this also (it’s free).
  3. Insert your computer into the audio signal flow of your TV.
    • If the TV has an audio output, connect the sound card line in to this outlet. Connect the sound card’s output to your usual listening devices (such as speakers or headphones).
  4. Listen and check if it sounds better. If still needed, adjust the frequency on your computer. How much and whether you need to adjust will depend on the speed of your computer.

Consumer Reports shows several easy ways to reduce the noise of the vuvuzela. Note that it doesn’t recommend paying money to do this!

Tips

  • Mute it. Watch in peace!
  • The vuvuzelas can pump out as much a 131 decibels.[4]
  • Apparently the horn “drones” (is at its most annoying) at 233Hz.[5]

Warnings

  • Not all TVs have a built-in equalizer. If you can’t find one, try one of the other methods instead.

Things You’ll Need

  • Computer for first option
  • TV or stereo for both options
  • Speakers or headphones

    So the vuvuzuela is your rooster? I sure hope it doesn’t catch on here. I wake up to the sound of the surf and the birds. And my alarm clock, but that’s okay.

      LOL, I hardly wake up to that anymore (the alarm clock) now that I work nightshift. It’s a blessing, I hate alarms…

    Hahaha!! OMG this is so funny! I’m never going to be able to think of a vuvuzela … or Venezuela really either -lol-, without thinking of you and the vuvuzela debacle of 2010.

    • Alyssa June 30, 2010 / 11:54 pm
