Why does my mic pick up computer sounds?

**Why does my mic pick up computer sounds?**

If you’ve ever used a microphone during a voice call or while recording audio on your computer, you may have noticed that it sometimes picks up unwanted computer sounds in the background. This phenomenon can be quite frustrating, especially when you’re trying to obtain clear, high-quality audio. But why does this happen? Let’s delve into the reasons behind why your mic might be picking up those pesky computer sounds.

One of the primary reasons why your microphone picks up computer sounds is due to a phenomenon known as ambient noise. Ambient noise refers to the sounds present in your environment that can interfere with your desired audio. These sounds can include fan noises, keyboard typing, mouse clicks, hard drive spinning, and other electrical hums produced by your computer.

**How does ambient noise affect your microphone?**

When you use a microphone, it captures sound waves from its surroundings, converting them into electrical signals that your computer can process. However, ambient noises such as those emitted by your computer can also be captured by the microphone along with your intended audio. This happens because most microphones are designed to be sensitive to a wide range of frequencies, allowing them to pick up both your voice and the background noises.

**What can you do to reduce the impact of computer sounds on your microphone?**

While completely eliminating computer sounds from your microphone’s audio capture might not be possible, you can take several measures to minimize their impact:

1. **Use a directional microphone**: Directional microphones capture sound mainly from a specific direction, allowing you to focus on the audio source while reducing background noise.
2. **Adjust the microphone settings**: Use software or hardware controls to adjust the microphone’s sensitivity levels or activate noise cancellation features, which can help filter out unwanted sounds.
3. **Use soundproofing materials**: Consider placing soundproofing materials around your microphone or in your recording space to reduce external noise reflections.
4. **Position your microphone strategically**: Place your microphone closer to your mouth and further away from your computer to minimize the pickup of computer sounds.
5. **Opt for a higher-quality microphone**: Investing in a higher-quality microphone can improve audio fidelity while minimizing background noise pickup.
6. **Use noise suppression software**: Utilize noise suppression software or audio editing tools to reduce or clean up unwanted sounds in post-production.


1. Can using headphones with a built-in microphone solve the problem?

Yes, using headphones with a built-in microphone, often referred to as a headset, can help reduce the pickup of computer sounds. The close proximity of the microphone to your mouth, combined with the noise isolation properties of the headphones, can help mitigate background noises.

2. Does using a USB microphone make a difference?

USB microphones can offer advantages in terms of sound quality and have built-in features such as noise cancellation that can help reduce the pickup of computer sounds. However, the effectiveness may vary depending on the specific microphone model and its built-in capabilities.

3. Can adjusting sound settings on my computer help?

Yes, tweaking sound settings like volume and microphone levels on your computer can have an impact on reducing the pickup of computer sounds. Lowering the volume or adjusting the microphone sensitivity can help minimize unwanted audio interference.

4. Do external sound cards help in reducing computer sounds?

External sound cards can potentially improve audio quality and provide more control over sound settings. Some external sound cards have built-in features like noise cancellation, enhancing the microphone’s ability to filter out background sounds.

5. Is it possible to edit out computer sounds from already recorded audio?

Yes, it is possible to edit out computer sounds from recorded audio using audio editing software. By employing noise reduction or filtering techniques, you can isolate and reduce unwanted sounds in post-production.

6. Does the physical location of my computer affect microphone pickup?

Yes, the physical location of your computer can influence the amount of computer sounds picked up by the microphone. Placing your computer further away from your microphone or using physical barriers like soundproof screens can help reduce the unwanted pickup of computer sounds.

7. Can using a pop filter minimize computer sounds?

While a pop filter primarily helps in reducing plosive sounds (such as “p” and “b” sounds), it can also help reduce some computer sounds. It acts as a physical barrier between the microphone and the sound source, potentially reducing the pickup of unwanted noise.

8. Can using an audio interface eliminate computer sounds?

An audio interface can help improve audio quality, but its ability to eliminate computer sounds depends on the quality of the interface and its built-in features. Some advanced audio interfaces have better noise reduction capabilities.

9. Do post-processing techniques help mitigate computer sounds?

Yes, post-processing techniques such as noise reduction, EQ adjustments, and spectral editing can help minimize the impact of computer sounds on your audio recordings. These techniques can be employed using audio editing software.

10. Can using a pop-up recording booth minimize computer sounds?

Pop-up recording booths, also known as isolation shields or reflection filters, can help reduce unwanted reflections and some high-frequency computer sounds. However, their effectiveness in minimizing computer sounds is limited.

11. Does the type of microphone I use affect background noise pickup?

Different types of microphones have varying levels of sensitivity to background noise. Dynamic microphones are less prone to picking up computer sounds compared to condenser microphones because they have a more limited frequency response.

12. Can cleaning my computer reduce the noise picked up by the microphone?

Yes, a dusty or poorly maintained computer can generate more noise. Regular cleaning, particularly of fans and other moving parts, can help reduce the noise produced by your computer, thereby minimizing its pickup by the microphone.
