Designing an arcade machine with minimal noise output requires careful attention to several factors. First, selecting quiet components such as low-noise fans, solid-state drives (SSDs), and efficient power supplies can significantly reduce operational sounds. Second, soundproofing materials like acoustic foam or rubber dampeners can be installed inside the cabinet to absorb vibrations and block external noise. Third, the cabinet's construction should use dense, heavy materials like MDF (medium-density fiberboard) to minimize resonance. Additionally, proper ventilation design ensures cooling without excessive fan noise. Finally, regular maintenance of moving parts, such as joysticks and buttons, prevents squeaking and rattling. By addressing these elements, you can create a quieter, more immersive gaming experience.
