"But her final words were drowned as a different voice echoed through the hall. It was high, cold, and clear: There was no telling where it came from; it seemed to issue from the walls themselves."

— Effects of the Amplifying Charm

The Amplifying Charm (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. When using the charm on an inanimate object, one had simply point their wand at the device and either verbally or non-verbally incite the incantation.
