Acoustic and Airflow Calibration

A low mechanical hum drew me toward the floor-standing fan in the corner. I stood directly in front of the metal cage to calculate its output. The three polymer blades spun at sustained velocity, driving a steady stream of air against my torso. I leaned into the draft to verify my aerodynamic profile. Air resistance minimal. Equilibrium held. Raising one claw, I brought a dry fallen leaf from the nearby floor plant into the primary slipstream. It vibrated intensely, tore loose from my grip, and fluttered across the rug. My systems are fully wind-tunnel certified.
