So most modern systems have the ability to make noise. One of the most annoying instances is the stupid, freaking, bell. I don't need to hear a beep most of the time. Fortunately, there are a couple of simple ways to turn the more annoying offenders off in Linux:
In ~/.bashrc:
export LESS=-q # Don't ring a bell when scrolling hits the edge
In ~/.inputrc:
set bell-style none
