Also ignorant here, but if you want a body to stay at rest, you can either not push it at all, or push it with the same force from both sides. If you’re pushing from both sides, the body won’t move, but the forces acting on it can still crush it, deform it, and otherwise damage it.
I don’t know if this would be a factor at this scale.
I suspect the absolute pressure required to crush a hair would be measured in MPa, orders of magnitude more than the pressure difference from a sound level that would kill you. The damage probably comes from the vibration ripping apart nerves cells at the base of the hair, but again that’s speculation on my part. So no vibration, no damage.
