Welcome to the Apple Discussions!
Some folks use Statrtup Sound.
If you completely silence your Mac you remove its form of communicating issues to you during startup. The chime alerts you that the Mac has passed the POST, Power On Self Test and has found usable RAM. When it fails to do so it may sound other tones during startup to alert you to what is wrong.
You can do it with Mac OS X, but it is not a feature and you need a good memory. The Pref Pane is more secure.
If you mute your Mac before you shut down, there should be no Chime when you start up again. But you have to remember to mute, and you have to remember did you mute. The Pref Pane takes all that remembering away and gives you a sure thing. Plus, the volume setting in the pane only effects the volume of the Chime. All other volume settings are unaffected.
Try unplugging your external speakers and turn the internal speaker volume way down, then plug your external speakers back in. Now as long as the external speakers are plugged in the startup chime should only be as loud as the last setting for the internal speakers.
As suggested above just turn it way down, it's not a good idea to fully mute the startup chime!
