You basically start the following activity with ADB: adb shell am start -a android.settings.SOUND_SETTINGS
The app would do the same.
There you can disable notification sounds, which is also used on boot-up. Please note: the boot up sound can not be changed that way. If you want to have an individual sound, you have to follow the instructions how to root the device and replace the boot sound file with another one. An app could do that actually.
