How Pop Filters Reduce Keyboard Noise

does pop filter reduce keyboard sound

Pop filters are microphone accessories that mitigate plosive sounds, which are backed by a high amount of air when certain words are released from your mouth instantly. These words, such as 'b', 'd', 't', and 'p', can cause an unpleasant thumping or popping noise once the sound waves hit your microphone diaphragm directly. While pop filters are necessary for audio recording, they are not designed to reduce keyboard noise. To reduce keyboard noise, you can try using a noise gate, placing a towel over the keyboard, or using a dynamic mic.

Pop filters are designed to reduce plosive sounds, not keyboard sounds

Plosive sounds, such as the 'p' in 'popping', as well as 't', 'k', 'd', 'b', and 'g' sounds, can cause microphones to clip or distort. Pop filters attenuate the energy of these plosives, intercepting and breaking up the sound energy before it reaches the microphone's diaphragm. This prevents the microphone from clipping and maintains the clarity of the recorded voice.

Pop filters are different from microphone windscreens, which are used outdoors to reduce wind noise and on stage by vocalists to minimise plosives and saliva. Pop filters are more acoustically transparent and are positioned at varying distances from the microphone depending on the recording situation. While pop filters can be purchased, improvised pop shields can also be made with material from tights or stockings stretched over a kitchen sieve or hoop.

While pop filters can help reduce some background noise, they are not designed to eliminate keyboard sounds. To reduce keyboard noise, placing a towel over the keyboard or using a thin layer of silicon gel under frequently used keys can help. Adjusting the microphone's position or using a noise gate feature in recording software can also minimise the keyboard noise picked up by the microphone.

A noise gate can be used to remove keyboard sounds

To set up a noise gate, you can adjust the settings in your recording software or microphone. For example, in OBS, you can add a noise gate filter and tweak the close and open thresholds to determine when the mic turns off and on.

However, a noise gate will not prevent keyboard noise when you are speaking and typing simultaneously. In this case, the volume is above the threshold, and both the voice and noise will be heard. Advanced signal processing would be required to separate the click noise from your voice, but such filters can distort your voice and are not always effective.

Additionally, it is important to note that a noise gate will not completely remove keyboard noise from your audio. The goal is to minimize its impact without causing significant distortion to your voice. Other methods, such as using a microphone isolation chamber or software solutions like RTX Voice or Krisp, can also help reduce keyboard noise, but they may have their own limitations and glitches.

Overall, while a noise gate can be a useful tool for reducing keyboard sounds, it should be combined with other techniques and settings adjustments to achieve the best results.

A towel over the keyboard can help reduce the sound

A towel can be used to reduce the sound of a keyboard being picked up by a microphone. This can be achieved by placing a towel over the keyboard or mouse, or even over the hands. While this may not completely eliminate the sound, it can help to reduce it to a level that is less bothersome or noticeable.

Another option is to place a folded towel under the keyboard to isolate the desk noise. This can help to dampen the sound of the keyboard, particularly if the desk is made of a material such as glass. However, this method may raise the keyboard a few inches, which could be uncomfortable for the user and prevent the use of a wrist rest.

Instead of a towel, some people have suggested using foam, felt, cotton, or even a thin layer of silicon gel under the keys to reduce the sound. Others have recommended placing the keyboard on a mouse mat or a "Sound Dampening" mat, which can also help to reduce the noise.

Additionally, there are software solutions, such as setting up a noise gate on the microphone so that it cuts out when the sound drops below a certain level. This can be done through software like OBS or by adjusting the recording device settings in Windows.

A foam pad can be used to decouple the keyboard from the surface it's on

While a pop filter on your microphone can help reduce the sound of your keyboard being picked up, it does not eliminate the issue. A foam pad can be used to decouple the keyboard from the surface it is on, which can help to reduce the sound even further. This method is popular among gamers and other content creators who wish to reduce the sound of their keyboard being picked up by their microphone.

One of the most common issues with microphone setups is that the microphone picks up all the background noise, including the sound of the keyboard being used. This can be distracting and annoying for viewers or listeners. To combat this issue, many people have tried placing a towel over their keyboard or using a pop filter on their microphone. While these methods can help to some extent, they do not completely solve the problem.

A more effective solution is to use a foam pad to decouple the keyboard from the surface it is on. This helps to reduce vibrations and ping, creating a deeper and less annoying sound. By adding mass and dampening to the keyboard, the foam pad restricts vibrations and prevents sound from reflecting off the surface back up to the microphone. This method is especially useful for aluminium boards, which are more prone to vibrations.

Additionally, the construction of the desk that the keyboard is placed on can also make a difference. Desks made from different materials will sound different when tapped on, and this will impact the sound of the keyboard when typed on. Placing a rug or other material underneath the desk can also help to reduce the vibration transferred from the desk to the floor.

Overall, using a foam pad to decouple the keyboard from its surface is an effective way to reduce keyboard sound, creating a more pleasant listening experience for viewers and listeners.

Quieter keyboards are available

While a pop filter can help reduce the popping sounds caused by plosive consonants, it won't do much for keyboard noise. If you're looking for a more permanent solution to reduce keyboard noise, consider investing in a quieter keyboard.

Logitech, for example, offers a range of quiet keyboards designed for a peaceful typing experience without sacrificing performance. These keyboards feature silent keys that reduce the loud key clacks, allowing you to work or game without disturbing others. The collection includes wireless keyboards, Bluetooth keyboards, and keyboard and mouse combos in various colours and designs to match your workspace aesthetic.

Some keyboards in their quiet collection include:

  • A minimalist rose wireless keyboard and mouse combo with an ultra-thin, compact, and whisper-quiet design.
  • An off-white wireless keyboard and mouse combo featuring silent keys for a quieter workspace.
  • A graphite wireless keyboard and mouse combo designed for seamless business productivity and comfort.
  • A compact, illuminated Bluetooth keyboard in graphite, refurbished to high standards.

In addition to purchasing a quieter keyboard, you can also try some temporary solutions to reduce keyboard noise. For example, placing a towel over your keyboard or hands can help muffle the sound, although it may not be practical for extended periods. Another option is to place a thin layer of silicon gel under the most frequently used keys to make them quieter, but be careful not to apply too much, as non-working keys can be more frustrating than loud ones.

Frequently asked questions

No, a pop filter does not reduce keyboard sound. It is designed to reduce plosive sounds produced during vocal recordings, such as 'p' and 'b' popping sounds.

There are several methods to reduce keyboard noise:

- Use a noise gate: This cuts off the microphone when the sound drops below a certain level, such as during silent parts.

- Adjust microphone position: Move the microphone closer to your mouth and away from the keyboard.

- Use a directional microphone: Position the microphone so that it picks up audio from your mouth and not the keyboard.

- Place a foam pad under the keyboard: This decouples the keyboard from the surface and reduces the transmission of vibrations through the desk.

- Use a quieter keyboard: Some keyboards produce less noise than others.

Yes, you can use audio editing software to reduce keyboard noise during post-production. For example, you can use noise reduction tools in software such as Audacity or Adobe Audition.
