How to switch off the annoying beep?

[Christoph Georgi]

Hi,

every time Thunderbird receives some emails, my notebook makes this 
annoying beep. The same beep sounds whenever one tries to click 
somewhere allthough one can't or when you for example hit the backspace 
in a terminal although noting is written in it .

Is there any way to turn that beep off? (sry for my bad expination, but 
I don't know how to describe better...)

Thanks for any help.
