How to compare microphone pickup with curtains closed

You close the curtains and wonder if your microphone sounds different. The change might be less outside noise, less room echo, or simply a different speaking distance. A careful side-by-side test can help you separate those effects.

Use the Microphone Test to watch the input level and waveform, then record the same short sentence with the curtains open and closed. Keep the microphone and your position fixed so the room is the main thing that changes.

Compare the microphone with curtains open and closed

1. Open the Microphone Test and press Start microphone. Allow microphone access when the browser asks. Choose the microphone you want to test from the device list.
2. Place the microphone and your chair where you normally use them. Mark or note their positions, and keep the microphone the same distance from your mouth for both recordings.
3. With the curtains open, wait for the room to settle. Leave the test's Noise suppression, Echo cancellation and Auto volume switches in the same positions for both conditions.
4. Say the same sentence at a similar volume, then use Record 5 seconds and play it back. Note the signal meter's loudest level and listen for background sound, echo or a hollow quality.
5. Close the curtains without moving the microphone or chair. Repeat the same sentence and recording, then compare the meter, waveform and playback. If you want a more reliable comparison, repeat both conditions once more.

Try to keep other conditions steady too. Avoid changing the microphone's angle, speaking louder, turning on a fan, or moving closer to a window between recordings. If someone else is in the room, ask them to stay quiet during each five-second recording.

What the result means

The closed-curtain recording sounds less echoey

The curtains may be absorbing some sound reflections. That can make your voice sound less roomy, especially if the curtains cover a large, hard window or wall near the microphone. It does not mean the microphone has become more sensitive. The room is changing the sound that reaches it.

Background noise is lower with the curtains closed

The curtains may be reducing some sound from outside, such as traffic or people nearby. The effect depends on the curtain fabric, the window and the noise source. Curtains can soften sound, but they are not a soundproof barrier, so a loud or low-pitched noise may still be easy to hear.

The meter changes, but playback sounds about the same

The signal meter shows input level, not a complete measure of voice quality. A small level difference can come from speaking slightly louder or changing distance by a few inches. Compare the recordings at the same playback volume and listen for the kind of change you care about, rather than treating a single meter reading as a verdict.

There is little or no noticeable difference

The curtains may not be near the main sound-reflecting surface, or the room may already have little echo. They may also do little to block the sound you are testing. If the issue is a computer fan beside the microphone, for example, curtains across the room are unlikely to make much difference.

The closed-curtain recording sounds worse

Check that you did not change your distance, angle or speaking volume. If the room is quieter but your voice sounds duller, the curtains may be absorbing some of the higher-pitched detail along with reflections. Try placing the microphone closer to your mouth and away from the curtains, then compare again.

How to make the comparison fair

1. Keep the same microphone selected. A computer may switch from a headset mic to a built-in mic when a device reconnects. On Windows 11, check Settings › System › Sound › Input. On macOS, check System Settings › Sound › Input, then select the same device for both recordings.
2. Keep the input level steady. Do not change the microphone's input volume between takes. On Windows 11, look under Settings › System › Sound › Input for the selected device's input controls. On macOS, use System Settings › Sound › Input and leave the input volume unchanged.
3. Keep processing switches unchanged. Noise suppression can reduce steady background sound, while echo cancellation can change how room reflections are heard. Auto volume can raise or lower the level. Leave all three in the same positions so they do not confuse the comparison.
4. Use the same speaking distance. Put the microphone on a stable surface and speak from the same spot. A small change in distance can alter the voice level more than closing the curtains does.
5. Record when the room is quiet. Pause music, fans or nearby conversations if possible. If the sound you want to check is intermittent, repeat the test at a time when it is present and note that it may not occur in every recording.

What this test can tell you

The test lets you compare the sound arriving at one microphone under two room conditions. The waveform and signal meter help show whether the input changed, while playback helps you judge echo, noise and voice clarity. For a fair comparison, treat the meter as a relative reading between your own takes, not as a calibrated measurement of room noise.

This test does not measure a microphone's pickup pattern or prove that a curtain blocks a specific amount of sound. A microphone's pickup pattern describes which directions it hears best, and a browser test cannot map that pattern. The recordings do help you decide whether the change is audible in your actual setup.

The five-second recordings stay on your device.
