How to evaluate background noise for a language exam

A fan, traffic outside, or people talking nearby can make it harder to hear questions and can distract you while speaking. If you need to check whether a room is suitable for a language exam, start by measuring the noise in the actual space where you plan to take it.

The Noise Meter uses your device's microphone to show an approximate noise level in decibels. Use it to compare locations and notice changes, not as an official exam certification or a substitute for the exam provider's rules.

Measure noise in your exam space

1. Open the Noise Meter on the device you plan to use for the exam. Allow microphone access when the browser asks.
2. Place the device where it will be during the exam, with the microphone unobstructed. Stay quiet and let the reading settle for about 30 seconds.
3. Note the reading and any changes you hear, such as a fan cycling on or traffic passing. Repeat the check two or three times so one unusually quiet moment does not decide the result.
4. Try other possible spots in the same way. Keep the device, its position, and the test length consistent so the comparison is useful.
5. Speak at your normal exam volume and check whether your voice is easy to hear above the room noise. The quiet-room reading alone does not show how clearly an examiner will hear you.

If you are using a phone or laptop with a built-in microphone, keep its orientation the same each time. A headset microphone may pick up less room sound than a microphone across the desk, so test the setup you will actually use.

What the reading means

The reading stays fairly steady

A steady reading suggests the room has a consistent background sound, such as ventilation or a computer fan. Listen to the sound as well as watching the number. A low, steady hum may be less distracting than sudden noise, but it can still affect what the microphone picks up.

The reading rises and falls

Intermittent sounds such as passing cars, footsteps, or a neighbor's door can cause brief increases. Repeat the check at another time if the sound is occasional, and consider whether it is likely to happen during your exam. A single quiet reading cannot rule out a noise that comes and goes.

The reading is high or your voice is hard to hear

Find the source and test another position or room. For a speaking exam, also listen for whether your voice sounds clear and close, rather than distant or covered by background sound. The Noise Meter does not decide whether your room meets an exam's requirements.

You are not sure whether the number is good enough

There is no universal decibel cutoff for every language exam. Requirements depend on the exam, the equipment, and whether you take it at home or at a test center. Check the instructions from your exam provider, especially if it sets rules for headsets, room noise, or remote proctoring.

How to reduce distracting noise

1. Move away from the noise source. Try a room farther from a street, shared wall, kitchen, or hallway. Recheck the new spot with the same device position.
2. Close doors and windows. This can reduce traffic and household sounds. If a fan or air conditioner is noisy, turn it down or off only if it is safe and comfortable to do so.
3. Position the microphone consistently. Put a headset microphone near the corner of your mouth, not directly in front of your breath. Keep the microphone and your speaking distance the same when comparing readings.
4. Check microphone permission and input level. In your browser, use the site controls beside the address bar to allow microphone access. On Windows 11, open Settings › Privacy & security › Microphone and check microphone access. On macOS, open System Settings › Privacy & Security › Microphone. On iPhone, check Settings › Privacy & Security › Microphone; on Android, check Settings › Apps › your browser › Permissions › Microphone. If your voice is too quiet, check the input level in Windows under Settings › System › Sound › Input, or on a Mac under System Settings › Sound › Input.
5. Choose another time or room. If noise depends on traffic, construction, or other people at home, test at the time your exam is scheduled. If no location works, ask the exam provider what alternatives are allowed.

Why readings can differ between devices

A phone and a laptop can show different readings in the same room. Their microphones, placement, input levels, and built-in sound processing differ. Treat the number as a way to compare spots on the same device, not as a precise measurement you can directly compare with a friend's result. See why phone and laptop noise readings differ for more on those differences.

The meter measures sound reaching the microphone, not every sound in the room. A microphone's position and any device processing can change what it picks up. Your microphone audio is processed in the browser and is not uploaded by the Noise Meter.
