Acoustic Test

My grip on the megaphone tightened as warmth filled my plastic fingers. I lowered my raised left fist slightly, testing joint mobility, then brought the horn closer to test resonance. With a sharp breath, I whispered a formal protocol check into the mouthpiece. The acoustic feedback hummed softly against the cardboard poster behind me. The bobblehead figure beside me remained motionless on its base. Movement confirmed, amplification operational.
