Boosting Audio Output under Ubuntu Linux

I often had the problem when I wanted to watch a movie or listen to some audiofile and there was background noise I wanted to turn up the volume but it was already at 100% . I thought it should be possible to turn up the signal beyond 100% and decide by myself if the signal is clipping/distored. And there is a very easy solution for the people using pulseaudio.

Just install the tool paman

sudo apt-get install paman

Now you can boost the audio to 500% volume. For me usually 150% was enough ;).
