turn startup sound low

can anyone tell me how or where to turn startup / shutdown sound low whenever i boot up the sound is so bloody loud i NEED to turn down .

 

i know that this pretty simple task just turn my volume down but is there no other way to keep the win xp sounds low whilst the other sounds are at normal listening level

 

if there is no other way to keep the startup and turn off computer sound soft and still keep all other sound at normal level . then i will do so also will this effect windows other sounds eg : if email arrives or error sounds

thanks for the help
