[ Mechanical FX ] It’s mechanical sound effects,As a significant branch of sound artistry, mechanical sound design encompasses a wide range of fields. This includes the flight of aircraft through the skies, the movement of cars on roads and vessels across oceans, the operation of machinery in factories, the motion of robots performing tasks, and even subtle actions like turning valves or tightening screws—all fall within the scope of mechanical sound effects.

Taking [Transformers] as an example, when Optimus Prime transitions from vehicle mode into a towering colossus of steel, the rich and intricate mechanical soundscape audiences hear represents a quintessential application of this category. These sounds not only enhance the film’s realism but also immerse viewers in a universe brought to life through mechanical beings.
