Your Discord microphone picks up background noise mostly because the input sensitivity or gain is set high, noise suppression is off, or you are using an omnidirectional or built-in laptop mic that hears the whole room. Open Discord, go to User Settings, Voice and Video, turn on Noise Suppression, and set Input Sensitivity so it triggers only when you speak.
Why this happens
- High input volume or auto gain. The mic level is turned up so far that fans, keyboards, and room noise come through clearly.
- Noise suppression off. Discord's built-in suppression is not enabled, so steady background sound is not filtered out.
- Open microphone type. Built-in laptop and cheap desktop mics are omnidirectional and sit far from your mouth, so they capture everything.
- Sensitivity too low. The voice activity threshold is set so low that quiet sounds keep the mic open.
- Wrong input device. Discord may be using a webcam or monitor mic instead of your headset.
- No isolation. Fans, air conditioning, and hard walls that reflect sound all add constant noise.
Is this normal?
Some background pickup is normal with any microphone, especially built-in ones. Excessive constant noise usually means settings, not broken hardware.
Does it cause any problems?
It does not harm your PC or mic, but it makes you harder to understand and is tiring for others on the call.
How to fix or check it
- In Discord, open User Settings (gear icon), then Voice and Video.
- Under Input Device, select your actual microphone or headset, not a webcam or monitor.
- Turn on Noise Suppression (the Krisp option) to remove steady background sound.
- Turn on Echo Cancellation and Noise Reduction under Voice Processing.
- Switch Input Sensitivity from automatic to manual, then talk normally and set the slider just above the level your background noise reaches, so the bar only lights up when you speak.
- Lower Input Volume if your voice is already loud enough, which reduces how much quiet noise gets through.
- Use Push to Talk if your environment is very noisy, so the mic only opens when you hold a key.
- On Windows, open Sound settings, select your mic, and turn off Microphone Boost if it is set high, since boost amplifies noise too.
Frequently asked questions
Does Discord noise suppression work well?
Yes, the built-in Krisp suppression removes most steady sounds like fans and typing. It can slightly clip your voice, so test it and lower it if your speech sounds cut off.
Why does my mic pick up my keyboard so much?
Mechanical keyboards are loud and often sit right under a laptop or desktop mic. Noise suppression helps, and moving the mic closer to your mouth lets you lower the gain.
Should I use automatic or manual input sensitivity?
Manual gives more control in a noisy room. Set it just above your background level so the mic stays closed until you speak.
