This is typical disinformation from you sankey.
I will bring a 30 cu ft air stage with me when teaching mix. If the student
wants, (his choice only) I will let him breath on the stage at 170' for a minute
or so.He can experience narcosis. Most students do not believe the amount of
impairment on air, and this exercise shows them the difference. I remain on mix
the whole time, and 170 feet is sufficient for the demo.
If this is promoting deep air so be it.
Von
