Comparing sound to light of any frequency is wrong. Light causes damage at a chemical level: heat, photochemical and ionization. It damages our cells. While light carries energy, it must interact with our tissue to deposit that energy and that interaction is quantum, i.e. frequency-dependent. Sound causes mechanical damage to organs. It works at a different scale. So intuition about the relationship between waves and harm is unrelated between light and sound, analogies between the two are not very useful.
