Sonic arrows are used on green-hued soundstone to break them, opening up areas for puzzles, or can be used in combat to push around enemies. Sonic Arrows are really helpful in building up an enemy's stun meter, allowing for devastating damage once it is filled. Sigil Arrows are a type of magical arrow that is equally helpful for stun meters, but more importantly, they combine with the frost damage of the Leviathan Axe, the fire damage of the Blades of Chaos, and other elemental effects to increase said damage.
