Soundproof Air-Flow Box for Chocolate Machine

I'm in need of a soundproof box that can be placed over a small chocolate machine. This box should not just mute the noise produced by the machine but also allow a free flow of air to prevent overheating. The box should also have a minimal volume, meaning it shouldn't take up too much space. Key Requirements: - Internal storage dimensions of the box should be approximately 14x14x22. - The material of the soundproof box is not pre-determined. Your recommendation for the most appropriate and effective material is welcomed. - The soundproof box should be designed to allow a free flow of air in order to prevent overheating of the small chocolate machine or so that active cool air can be introduced. - The top should open or slide off so that ingredients can be added easily. -A hole for the powercord must be introduced in a way that does not jeopardize sound proofing. The ideal freelancer for this project would have experience in soundproofing and air flow systems. Any prior experience with creating soundproof boxes for machinery would be a huge plus. Your expertise and creativity in design to align with the minimal volume requirement would be highly valued. I'm open to discussing any potential customization needs or additional features that would enhance the functionality of the soundproof box.
