I don't mind the one turn cooldown. Sound has almost no way to resist it in the game, as opposed to all other elements, and also has the highest rate of inflicting injuries in serious combat by a good margin as well. And Bards also have Tune-up.

Sound wave also being 110% SWA and 90% Sound is probably better overall than 100/100 spells, though still inferior to Famiuga's 140% Ice attack probably.
And if your target has sanctity? Well, sanctity doesn't give sound resistance, but gives pretty much all other magical elements. So you're still outdamaging those just by default. (Though Famuiga also takes around 3x as many class points to acquire and max)

Though I guess Ranger still has a 0 cd 130% Sound scaling spell, so its probably fine to remove the cooldown. But then again, Ranger just gets way more mileage out of spamming the earth arrow, the ice arrow, or flip shot so I basically never see anything else used regardless.

All the other sound moves in the game as far as i'm aware have cooldowns, and there's also ring of the dancer to think about.

Sound and acid are both very scary elements so i'm always going to be tentative about giving people more ways to use them, but its probably not going to break the game if the cooldown is removed.
