How to remove the sound component from certain spells?

Thunder

Spell such as Web and Entangling Roots have (in my opinion) unnecessary and annoying sound effects. Is there any way to remove the sound from specific spells?

Wisp

You can remove most spell sounds. Places to look are among the extended effects in the spell itself and in the spell's projectile. From there on it depends on which sounds you want to remove and which spells you want to remove them from.
