Music
If watching the World Cup has you feeling like you live in a building filled with enraged, sleepless bees, you can try filtering out the vuvuzelas’ distinctive dentist-drill whine, using a computer or a TV with a good equalizer:
For the Vuvuzela-killer, we need only a high-slope band stop filter that takes out the corresponding frequencies. For this, in principle, any modern computer that has a sound card with low latency and corresponding software should work. In our case, we used a Mac Mini and Logic Express 8. (Actually, such a complex software such as Logic Express is not necessary. We use it only because it was already on it on the computer and the necessary filters are included.)
