Why Are Mechanical Keyboards So Loud?

Last Updated on December 6, 2023

Mechanical keyboards are the preferred choice of many typists and gamers due to their durability, responsiveness, and tactile feedback. However, one aspect that sets them apart from other keyboards is their loud clicking sound. In this article, we will delve into the reasons why are mechanical keyboards so loud and explore ways to reduce their noise levels.

Mechanical Keyboards vs. Membrane Keyboards

Before we explore the reasons behind the loud clicking sound of mechanical keyboards, it’s important to distinguish between mechanical and membrane keyboards. Membrane keyboards are the most common type of keyboard found on laptops and standard desktop computers. They work by using a thin layer of rubber or silicone under the keys to register keystrokes.

In contrast, mechanical keyboards use individual mechanical switches for each key, which provides a more tactile feel and faster response time. The mechanical switches also require more force to actuate, which is where the clicking sound comes from. When a key is pressed down, the stem of the switch moves downwards and makes contact with a metal contact point. The sound is produced when the stem hits the contact point and bounces back into its original position, creating a distinct clicking sound.

Different types of mechanical switches have different levels of actuation force and feedback. Some switches may produce a louder clicking sound, while others may be more quiet and subtle. Additionally, some switches may have tactile feedback, which means that the user can feel a small bump when the key actuates. This tactile feedback is especially useful for touch typists who rely on the feel of the keyboard to type accurately.

In summary, the loud clicking sound of mechanical keyboards is a result of the unique design of the switches, which provide a more tactile and responsive typing experience. While the sound may be distracting to some users, many people appreciate the satisfying sound and feel of typing on a mechanical keyboard.
