Princess Luna stalked the halls of Canterlot Palace.

"Forsooth," she lamented out loud. "We art so lonely now that We art no longer the only living creature on Our entire world. If only We had a friend here in Equestria to call Our own."

Through the window, the moon was slowly rising through the starry night. It was a lovely contrast, the light of the moon on the dark marble tile of the night court's floor, as if it were a glittering mirror seen through-

"We said," she repeated, a little louder. "If only We had a friend to call Our own!"

"Mwahahaha!" the human stepped through a nearby door. "I'm immune to magic and I'm here to conquer you!"

"HUZZZAH!" Luna shouted, rearing up and clapping her hooves happily. "WELCOME, FRIEND!"

"Ack, turn down the volume," he cringed back. "That's seriously loud."

"BUT WE ART OVERJOYED AT THY PRESENCE!" she shouted even louder, stepping forward and reaching for snuggles. "AND WE WISH TO EXPRESS OUR JOY!"

"Gahhh," the human spluttered, clutching his ears and writhing in agony as she approached. "I think I've just gone deaf!"

"THOU ART DEAF?" Luna inquired. "WE CAN REMEDY THIS! JUST ONE MOMENT, PLEASE."

Fishing around in her mane, the princess pulled out a megaphone and applied it to her lips.

"CANST THOU HEAR US NOW?"

"Please...stop," the human fell to his knees, desperately trying to shield his ears as blood started dripping from them.

"WHAT?" she shouted even louder. "SURELY OUR SPEECH REMAINS NOT STILL OCCLUDED FROM THINE EARS? OR IF NOT THINE EARS, THEN AT LEAST THY SKULL SHOULD PROVE SUITABLE FOR BONE CONDUCTION."

Seeing the human now spasming uncontrollably on the ground, Luna came to the obvious conclusion that the volume setting on the megaphone was simply too low, so she turned the dial up to 11 and held it up against his twitching head.

"CANST THOU HEAR US NOW?"

Fun fact: sound up in the 185 decibal range can kill you. Not very different from the pressure wave of an explosion.

No magic required.
