Knownly Amplifying Charm

The Amplifying Charm - see this URL (Sonorus) was a charm that could be used to amplify the targeted sound, be it a person's voice or a piece of equipment. The counter-charm to this spell was the Quietening Charm.
==Effects==
This charm was particularly useful for amplifying one's voice, although using it on oneself for a long period of time will result in hoarseness thereafter.
