The noise level of a CNC router machine varies depending on its type, size, components, and the material being cut. Here's a concise overview:

Typical Noise Levels:

Hobbyist/Small CNC Routers: These produce noise in the range of 70-85 decibels (dB), comparable to a vacuum cleaner or loud conversation. Desktop models, especially when cutting softer materials like wood or foam, tend to be quieter.

Industrial/Professional CNC Routers: These can generate 85-100 dB or more, similar to a lawnmower or chainsaw, especially when cutting dense materials like metal or hardwood at high speeds.

Factors Affecting Noise:

Spindle/Motor: High-speed spindles (e.g., 10,000-24,000 RPM) are a primary noise source. Air-cooled spindles are often louder than water-cooled ones, which can reduce noise by 5-10 dB.

Material: Cutting harder materials (e.g., aluminum, steel) creates more noise due to increased resistance and vibration compared to softer materials like MDF or plastic.

Tooling and Speed: Dull tools or high feed rates increase noise due to strain on the machine. Certain bits, like larger diameter ones, can also be louder.

Machine Design: Machines with poor vibration dampening or lightweight frames amplify noise. Industrial models with robust enclosures may reduce sound output.

Dust Collection Systems: Attached shop vacuums or dust extractors can add 10-20 dB, often reaching 80-90 dB on their own.

Environment: Enclosed CNC routers or those in soundproofed rooms are significantly quieter externally, sometimes dropping effective noise by 10-20 dB.
