Not so much before it becomes really dangerous and unpractical.

What supports those objects is the pressure differences generated
by the standing waves. Now 120 dB SPL is 20 Pa, or 2 kg / m^2, or
2 milligrams per square millimeter. Which suggests they are already
using more than 120 dB SPL.

BTW, 120 db SPL is also around 1 W / m^2, so harvesting energy from
sound panels (similar to solar panels) is another idea that won't
go far.
