If you’re considering buying a laser engraver, one question you might be asking is: Are laser engravers loud? The answer depends on a few factors—such as the type of machine, the materials you’re working with, and what accessories you’re using.
In this guide, we’ll break down how loud laser engravers really are, what contributes to the noise, and how to reduce it so you can create comfortably at home, in an office, or a shared workshop.

How Loud Is a Laser Engraver?
Most desktop laser engravers produce noise levels between 40 to 70 decibels (dB) during normal operation. For comparison:
- 40 dB = Quiet library
- 60 dB = Normal conversation
- 70 dB = Loud vacuum cleaner
So while laser engravers aren’t deafening, they can still be distracting—especially in quieter settings or if you’re working for long periods.
Here’s a quick comparison of typical noise levels from popular types of laser engravers:
Laser Type | Average Noise Level | Common Source of Noise |
|---|---|---|
Diode (e.g., xTool M1, S1) | 45–60 dB | Cooling fans, motors, and moving parts |
CO2 (e.g., Glowforge, xTool P2) | 60–70+ dB | Larger fans, more powerful motors |
Fiber (e.g., xTool F1 Ultra) | 50–65 dB | High-speed scanning systems |
What Makes Laser Engravers Loud?
Several components contribute to the overall noise level of a laser engraver:
- Cooling Fans: All laser machines require cooling—some use air-cooled fans while larger CO2 models might use water cooling systems with pumps, which can be noisy.
- Exhaust Systems: Ventilation is essential for filtering out fumes. External exhaust fans or air purifiers can add another layer of sound—often louder than the laser itself.
- Stepper Motors: The motors that move the laser head or material bed create mechanical noise, especially during fast or complex jobs.
- Air Assist: Air assist units, used to reduce scorching and improve cut quality, often include their own fan or compressor, which adds to the sound.
How to Reduce Laser Engraver Noise
If the sound level is a concern for your home, studio, or classroom, here are a few practical ways to lower the noise:
Use a Laser Enclosure or Acoustic Housing
A laser enclosure helps contain both noise and fumes. Look for enclosures that are ventilated and sound-dampening.

The Cregrant3D Updated Integrated Laser Engraver Enclosure is a well-designed, highly effective solution for reducing noise, smoke, and odors during laser engraving. Its large 720x720x400mm size fits most laser engravers, including xTool, Ortur, Atomstack, Sculpfun, and Creality machines, with enough room to install rotary rollers for more advanced projects.
One standout feature is the bottom-integrated stitching, which helps trap smoke and debris more efficiently than standard zipper-bottom tents. The addition of a 5W LED light strip improves visibility while engraving, and the PVC viewing window adds an extra layer of eye protection by filtering harmful blue light.
This enclosure includes a powerful 4000 RPM ventilation fan and an upgraded triple-layer exhaust hose, which does an excellent job at removing smoke and minimizing lingering odors. It’s easy to assemble, foldable for storage, and reinforced with all-metal support rods for improved durability.
Verdict:
An excellent laser engraver enclosure that significantly improves your work environment by dampening noise, removing smoke, and providing better visibility and safety. A great investment for hobbyists and small business owners alike.
Best for: Noise reduction, smoke control, and improved safety during engraving sessions.
Install a Quieter Inline Exhaust Fan
The exhaust fan is often the loudest component. Replacing it with a quieter inline fan helps drastically.

JBER Acoustic Foam Panels (12-Pack)
The JBER Acoustic Foam Panels (1″ x 12″ x 12″) are an excellent, budget-friendly solution for reducing laser engraver noise in small workshops or creative spaces. Crafted from high-density 30kg/m³ polyurethane foam, these wedge-shaped panels effectively absorb sound reflections and dampen ambient noise, improving the acoustic environment in studios, offices, and hobby rooms.
They are fire-resistant and eco-friendly, expanding quickly to their original shape after unpacking. With a total coverage of 12 square feet, they’re ideal for customizing noise control setups around noisy devices like diode and CO2 laser engravers.
Perfect for creators, remote workers, gamers, and small business owners, the JBER panels offer a simple way to elevate focus and reduce distractions caused by machine operation.
Verdict:
A great acoustic upgrade for anyone using a laser engraver in a shared or home workspace. Reliable noise reduction, fire safety, and affordability make them a smart pick.
Best for: Reducing laser engraver noise in small to medium-sized rooms with easy wall-mount installation.
Bonus Tips:
- Keep your laser well-maintained: Dirty bearings and fans work harder and louder.
- Use slower speeds: Slower operation can be quieter and more precise.
- Engrave during the day: Helps avoid disturbing others at night.
Are Some Laser Engravers Quieter Than Others?
Yes—generally, diode lasers (like the xTool M1 or S1) are the quietest options. They have smaller motors and lighter-duty fans, making them ideal for home users or shared spaces.
CO2 lasers, on the other hand, tend to be noisier due to larger exhaust systems and higher-powered cooling needs. If you’re cutting thicker materials or running production jobs, the increased noise is a trade-off for performance.
Is Laser Engraving Loud Enough to Bother Neighbors?
In most cases, the sound level from a diode or enclosed laser machine is unlikely to disturb neighbors through standard walls. However, in apartments or thin-walled studios, it might be noticeable—especially the hum of the exhaust fan or cooling system.
To stay considerate:
- Run the machine during daytime hours.
- Avoid prolonged sessions in the evening.
- Add rugs or foam to dampen vibrations if needed.
Frequently Asked Questions
How loud is a typical laser engraver?
Most desktop laser engravers operate between 40 and 70 decibels (dB) depending on the model and accessories. That’s about as loud as a normal conversation (60 dB) or a vacuum cleaner (70 dB). Diode lasers (like the xTool M1 or S1) tend to be quieter, while CO2 and fiber lasers may generate more noise due to more powerful fans and motors.
What are the main sources of noise in a laser engraver?
The primary sources of noise in a laser engraver include:
Cooling fans (for air or water circulation)
Stepper motors that move the laser head
Air assist compressors (if used)
Exhaust or smoke filtration systems
These components run simultaneously, and their combined sound can add up—especially in small or echo-prone spaces.
Are diode laser engravers quieter than CO2 or fiber lasers?
Yes, diode lasers are generally the quietest type. They use less powerful fans and motors and are ideal for home use or shared workspaces. CO2 lasers (like Glowforge or xTool P2) and fiber lasers (like xTool F1 Ultra) are more powerful and can be louder, especially when combined with high-CFM exhaust systems.
Can I reduce the noise of my laser engraver?
Absolutely. Here are a few ways to lower laser engraver noise:
Add an acoustic enclosure or laser housing
Choose a quieter air purifier or inline fan
Run the machine on lower power or slower speeds, if feasible
These measures help dampen motor hum and airflow noise, especially useful in home or office settings.
Will my laser engraver bother neighbors or housemates?
Most laser engravers won’t disturb neighbors through standard insulated walls, especially if you’re using a diode laser or an enclosure. However, in apartments, thin-walled studios, or late-night crafting sessions, the hum of fans or sudden movements can be noticeable. To minimize disruption:
Limit usage to daytime hours
Soundproof your workspace
Let housemates know your schedule if needed
Final Thoughts: Is Noise a Dealbreaker?
In short, laser engravers aren’t extremely loud, but they do make consistent mechanical noise. For most home users, it’s manageable—especially with quieter machines or proper noise reduction accessories.
If sound is a top concern, look for machines with quiet fans, smart cooling systems, or pair your laser with low-noise purifiers and inline fans (like those in the xTool SafetyPro Series).
