How to test your microphone
- Click Start mic test and choose Allow when your browser asks for microphone permission.
- Speak normally. The green waveform should move and the input level should rise.
- Click Record 5 sec & play back to hear your own voice – the best way to check quality, echo and background noise.
- If you have several microphones (built-in, headset, USB), choose one from the list and restart.

Level guide
| Level while speaking | Meaning |
|---|---|
| 0–5% | Not picking up – muted, wrong device or blocked |
| 10–60% | Good range for calls |
| Near 100% constantly | Too loud / distorted – lower input volume |
Built-in laptop mics vs headsets
Laptop microphones pick up keyboard and fan noise. For online classes, interviews or calls, a basic wired headset with mic sounds noticeably clearer. Windows also has noise suppression in Sound settings on many laptops.
Improve how you sound on calls
- Distance: keep your mouth about 30–50 cm from the laptop mic; closer for headset mics.
- Noise: turn off fans/AC near the laptop and close windows facing traffic.
- Typing noise: the built-in mic sits close to the keyboard; mute when you type.
- Windows enhancements: Settings → System → Sound → your mic → enable “Voice clarity” or noise suppression where available.
- App settings: Zoom, Meet and Teams all have background-noise suppression.
