    I found an old app called Silent Boot in the Play store. It is free and mutes all of the startup sounds on the SIII. The downside is that it doesn't mute the power off sound. Hopefully someone will find a fix for that, but at least we can turn our phones on without everyone in a three state area having to hear it. This is for unrooted devices, so no root is necessary.

    thanks, was looking for a way to do this. i can't fathom of a reason why you MUST have a boot sound that cannot be silenced from the factory settings.

    Copied from my other post answering this topic: (requires root)
    --------------------
    This is easy to do if your phone is rooted, and requires no modification to any boot animation or anything.

    Open a root explorer, go to /system/media/audio/ui.

    Rename the following two files as shown below (not mandatory for the names to match mine, they are just for example)

    PowerOn.ogg -> PowerOn.ogg.disabled
    PowerOff.ogg -> PowerOff.ogg.disabled

    From here, you can also get rid of camera and other annoying sounds from the phones UI.

    Hope this helps answer your question, but there is no non-root method that guarantees silence.

    You can also just press the pad of your finger firmly over the speaker while it is going. Pretty much cuts the audio.

    Just put phone on vibrate. No sounds shutting off or turning on except for a short vibration.

    I've silenced the "system volume." No more boot sounds or audible low battery warning. And I use tasker to silence the camera shutter sound. Handy.

    In a classroom when your phone is supposed to be OFF. So you try to turn it off and it is already off in that case it will boot and the boot sound is not silenceable. Everyone in the class is disrupted.
    Never the less the primary reason we ask is because we want it to be silenced which is reason enough for me.

    I'm a novice user, but muting the system volume did the trick for me!
