In shared office environments, noise matters. A loud keyboard can disrupt colleagues, break concentration, and create tension in open-plan spaces. As remote and hybrid work grows, more professionals are choosing their own peripherals—especially keyboards. Among the most common choices are mechanical and membrane keyboards. While both have loyal followings, one critical question arises for office workers: which type is quieter?
The answer isn’t always straightforward. Noise level depends not only on the switch or mechanism but also on typing style, keycap material, desk surface, and even room acoustics. However, when comparing general sound output, membrane keyboards are typically quieter than traditional mechanical ones. That said, advancements in mechanical switch design have narrowed the gap significantly.
This guide breaks down the acoustic profiles of both keyboard types, evaluates real-world performance in office settings, and offers practical advice for minimizing noise without sacrificing comfort or productivity.
Understanding Keyboard Mechanisms
To compare noise levels accurately, it’s essential to understand how each keyboard functions at a mechanical level.
Membrane Keyboards: How They Work
Membrane keyboards use a layered rubber dome system beneath the keys. When a key is pressed, the dome collapses, completing an electrical circuit on a printed circuit board (PCB). This action registers the keystroke. Because the movement is soft and cushioned by rubber, the tactile feedback is minimal, and the overall sound is muffled.
The absence of metal components clacking together means less mechanical noise. Most membrane keyboards produce a quiet \"thud\" or \"tap,\" especially when used with light finger pressure. This makes them inherently suitable for quiet environments.
Mechanical Keyboards: The Clicky Reputation
Mechanical keyboards use individual mechanical switches for each key. These switches contain metal springs, plastic housings, and sometimes metal contacts that click or snap when actuated. Brands like Cherry MX, Kailh, and Gateron offer various switch types—linear, tactile, and clicky—each with distinct sound signatures.
Clicky switches (e.g., Cherry MX Blue) are notoriously loud due to an audible \"click\" mechanism designed to provide auditory feedback. Tactile switches (e.g., Cherry MX Brown) offer a bump without the click, while linear switches (e.g., Cherry MX Red) are smooth and generally quieter. Even so, the spring rebound and keycap impact on the plate can generate noticeable noise.
Noise Comparison: Mechanical vs Membrane
Let’s examine actual noise output and contributing factors.
Decibel Levels and Typing Sound Profiles
Independent tests using decibel meters show that standard membrane keyboards average around 45–50 dB during regular typing—comparable to a quiet conversation. In contrast, mechanical keyboards with clicky switches can reach 55–65 dB, similar to normal speech or background office chatter. Linear mechanical switches fall in between, typically ranging from 50–55 dB.
However, peak noise—such as bottoming out keys (pressing all the way down)—can spike higher on mechanical models due to harder impacts against the PCB or plate. Membrane keyboards absorb this impact through their rubber domes, reducing sharp transients.
Typing Style Matters
A heavy-handed typist will make any keyboard louder. Mechanical keyboards amplify forceful typing because of their stiffer actuation and rebound. Light typists, especially those who “touch-type” without bottoming out, may find even linear mechanical keyboards acceptably quiet.
Conversely, aggressive typists on membrane keyboards might still generate distracting thumps, particularly on hard desks without padding.
“Switch selection and typing technique are bigger factors in keyboard noise than the category itself.” — David Lin, Peripheral Acoustics Researcher at Input Labs
Quiet Mechanical Options: Bridging the Gap
While traditional mechanical keyboards have a reputation for being loud, modern designs have introduced several innovations to reduce noise without losing the benefits of mechanical switches.
Silent Mechanical Switches
Manufacturers now produce “silent” versions of popular switches. For example, Cherry MX Silent Red and Gateron Silent Yellow feature built-in dampeners that suppress spring noise and reduce impact sound. These switches cut up to 20% of the typical mechanical noise while preserving the responsiveness users value.
These are ideal for office use—offering the durability and precision of mechanical keyboards with a much lower acoustic footprint.
O-Rings and Dampening Mods
Aftermarket O-rings or silicone dampeners can be installed under keycaps to soften landings. While effective, they can slightly alter typing feel and require careful installation. Some users report a “mushy” sensation if O-rings are too thick.
Alternatively, foam mods inside the case can eliminate hollow echo—a common source of perceived loudness in mechanical keyboards. DIY enthusiasts often add layers of anti-vibration foam to deaden internal resonance.
Keycap Materials
PBT plastic keycaps tend to produce a deeper, less sharp sound than ABS keycaps. Thicker keycaps (double-shot or high-profile) also help absorb impact noise. Pairing silent switches with premium PBT keycaps can result in a surprisingly quiet mechanical setup.
Office Suitability: Practical Considerations
Beyond pure decibels, workplace compatibility involves etiquette, ergonomics, and long-term usability.
Workplace Culture and Environment
In open offices or quiet libraries, even moderate noise can be disruptive. Membrane keyboards are less likely to draw complaints. They’re also more commonly provided by employers, making them the default “safe” option.
However, in hybrid setups where employees work remotely part-time, personal preference plays a larger role. A well-tuned mechanical keyboard used at home can travel to the office—if discretion is maintained.
Ergonomics and Typing Fatigue
While membrane keyboards are quieter, they often require more force to actuate and offer less tactile feedback. This can lead to finger fatigue over long typing sessions. Mechanical keyboards, especially those with linear or tactile switches, allow for faster, more accurate typing with less strain.
For knowledge workers spending hours writing emails, coding, or drafting documents, the ergonomic advantage of mechanical keyboards may outweigh minor noise concerns—especially when using silent variants.
Durability and Longevity
Membrane keyboards typically last 5–10 million keystrokes. Mechanical switches, by comparison, are rated for 50–100 million keystrokes. This longevity reduces long-term costs and waste, aligning with sustainability goals in many modern offices.
Though not directly related to noise, durability influences total cost of ownership and user satisfaction—important considerations for businesses equipping teams or individuals investing in personal gear.

Real-World Example: Quiet Typing in a Shared Workspace
Sarah, a technical writer at a mid-sized marketing firm, worked in a shared office with six colleagues. She initially brought her favorite mechanical keyboard with Cherry MX Blue switches—only to receive subtle complaints about the constant clicking.
Instead of switching back to her old membrane keyboard, she upgraded to a model with Gateron Silent Reds and added a thin foam layer inside the case. She also switched to thick PBT keycaps. The result? Her typing became nearly indistinguishable from a membrane keyboard, but she retained the speed and accuracy she relied on for long-form writing.
After two weeks, a colleague asked, “Did you get a new keyboard? It’s so quiet.” Sarah had found the perfect balance—performance without disruption.

Frequently Asked Questions
Can I use a mechanical keyboard in a quiet office?
Yes, but only if you choose a quiet variant. Silent linear switches, combined with dampening mods and proper typing technique, can make mechanical keyboards office-friendly. Avoid clicky switches entirely in shared spaces.
Are all membrane keyboards quiet?
Generally yes, but quality varies. Cheap, thin membrane keyboards may produce a plasticky tapping sound. Higher-end models with better construction and scissor-switch mechanisms (common in laptops) are the quietest options.
Do keyboard covers reduce noise?
Silicone keycovers can slightly muffle sound, but they often trap debris and alter typing feel. They’re not a reliable solution for noise reduction. Foam mods and switch selection are more effective.
Final Recommendation
For most office environments, membrane keyboards remain the safest choice when absolute quiet is required. They’re affordable, widely available, and inherently low-noise. However, dismissing mechanical keyboards outright would overlook significant advancements in silent switch technology.
If you value typing precision, durability, and long-term comfort, a well-chosen mechanical keyboard with silent switches can perform just as quietly—without sacrificing performance. The key is intentionality: selecting the right components, moderating typing force, and respecting shared space.
Ultimately, the quietest keyboard is not just about hardware—it’s about how you use it.
