The audio begins with the low, distant hum of an idle helicopter motor. As the engine is initiated, the hum grows into a resonant roar, filling the surrounding air with its powerful vibrations. The roar is accompanied by the rhythmic clatter of the rotor blades as they gradually come to life, their spinning speed increasing steadily. There's a distinct mechanical churn that underscores the growl of the engine, a testament to the intricacies of the helicopter's inner workings. The rotor's speed continues to escalate, creating a pulsating, rhythmic drone in sync with the engine's growl.
