Check before Teams, Zoom or Meet on Windows 11
Connect the microphone or headset you will use for Teams, Zoom or Google Meet to your Windows 11 PC. Open BENRI Microphone Test in your browser, choose the input device and speak normally.
Listen to a short recording to check for a voice that is too quiet, background music or household noise. After testing in BENRI, check that the calling app has selected the same input device.
Use the meter and your ears together
- Select the microphone and start the test.
- Speak normally, then stay quiet for a few seconds while watching the level and waveform.
- Stop and play the recording to judge speech clarity and background sound.
The dBFS reading describes the input signal. Compare speech with silence or compare settings before and after a change. It is not a sound-level measurement of the room.
The input level and waveform are shown with a test signal used for this example. (Japanese interface.)How to read the dBFS level
Values closer to 0 dBFS indicate a larger input. This display measures a short-term average level. Use around −25 dBFS while speaking as a practical target for a suitable call volume, then play the recording to check that your voice is clear.
Speech at −25 dBFS and pauses at −50 dBFS show that your voice is stronger than the background input. Change distance or input gain one step at a time and record the same sentence to compare the results.

Input-level targets to check before a call| Display | Input level | What to check |
|---|
| −50 dBFS | Very quiet input | Check whether the level drops this low during silence, and compare it with speech. |
|---|
| −40 dBFS | Quiet input | If speech stays around this level, listen to the recording to check clarity. |
|---|
| Around −25 dBFS | A practical target for speech during a call | Adjust distance or input volume while speaking normally, then listen back. |
|---|
| Around −6 dBFS | Very loud input | If the average is this high, listen for distortion in the momentary peaks of your voice. |
|---|
| 0 dBFS | The digital signal ceiling | Reduce the input volume and try again if the level keeps approaching this value. |

Choose a setup you have heard yourself
If your voice is quiet, adjust microphone distance or input volume. If background music stands out, change its playback volume or the speaker position. Each time you change one part of your setup, record a short sentence and listen to it. Compare it with the recording from before the change to hear the difference.
