The audio begins with the distinct click of a switch being flipped. Instantly, the stillness of the surrounding environment is replaced by a soft, rhythmic hum, a clear indication of power flowing. The hum is similar to the sound that electricity makes when it courses through a power line, a comforting, familiar noise that signifies the presence of energy. The noise is not harsh or grating, but rather a soothing, steady vibration that fills the space. It's a clear symbol of power being activated, of dormant machines waking up, ready to perform their functions. The hum continues, a steady reminder of the energy now coursing through the system, a testament to the power that has been turned on.
