How can I cause myself to go permanently deaf?

Well first of all, I hope you are not asking this so that you can do it and become deaf. I really hope this is not why you are asking this. Being able to hear and listen is a gift. If you are deaf, you cannot listen to music, you cannot hear the tornado sirens when you should take cover, you cannot hear you children call your name, you cannot hear your spouse say "I love you" so please do not try to become deaf if you have hearing. But ways that you can damage your hearing is by listening to your music too loud, epically if you have an Ipod or something like that. Also, a lot of pilots who fly fighter jets have trouble hearing. People who work in loud places, such as factories, often have damaged their ability to hear.
