Try making a [noise~] connected directly to a [dac~] and set the
headphone volume so you can live with that. Nothing will ever be
louder than that.
Hmm, I don't think that's actually true in all cases. On a MacBook Pro
running Mac OS X, I've had the volume set to one above mute, but had
massive feedback from LPC patches that were very very loud. [noise~]
would be very comfortable at that volume setting. I think some platforms
do the output mixing in the digital domain, so my min volume would be
[*~ 0.01], so that this would still make a very loud sound:
[noise~]

[*~ 999999]

[*~ 0.01] (i.e. the Apple output mixing)

In this particular case, the sound output actually gets shutdown
entirely, so you have to reboot to get sound output again.
That make no sense. How can you have two sounds at the same level going
into a mixer that come out at different levels? Or do you mean that a
squealing sound is perceived to be louder than white noise? Maybe you
could demonstrate with a patch?
