Have you ever wondered why there are such a variety of sounds on the fart soundboard? Well it’s because of the variety of fart sounds in real life. Fart’s produce sound because of the vibration they cause when we “let them rip” so to speak. The sound is dependent on the speed of the air coming out of the anal opening and the tightness of the opening. Since we can somewhat control the muscles in our anus, we can sometimes control the sounds. Most of the time we can’t control it too well though so we’re only either able to make a huge sound or a very slow hiss. The former we do when we’re comfortable and the second one we do when we’re trying to keep it really quite.

So the next time you fart why don’t you try experimenting with the sound it makes. Now that you’ve got the basic principles down you should be able to control the sound produced.
