Noisy open-plan office on calls: first checks

Customers complain that they can hear other agents, nearby conversations, or office equipment during calls. In an open-plan call center, it can be hard to tell whether the room is loud everywhere or whether one microphone is picking up too much.

Start by checking the room with the Noise Meter, then compare that with what the headset microphone picks up. These checks can help you find a practical fix without treating one browser reading as an official workplace noise survey.

Check noise around your workstation

1. Open the Noise Meter and allow the browser to use a microphone. Keep the device and its microphone in the same place for each reading.
2. Check the room during a quieter period, then again during a busy call period. Note the readings and what is happening nearby, such as several people speaking, a printer running, or an air vent starting.
3. Repeat the check at your usual seated position and at a nearby position, keeping the microphone at about the same height. A noticeable difference can point to a local source or a noisier part of the floor.
4. Open the Microphone Test, choose your headset microphone from the list, and press Start microphone. Speak at your normal call volume and watch the signal meter and waveform.

For a useful comparison, avoid moving the microphone, changing its input level, or switching devices between room checks. Write down the time, location, and nearby activity alongside the reading. This gives you more context than a single number.

What the results mean

The room reading rises when nearby agents speak

The sound is likely reaching your workstation from surrounding conversations. If the level rises during busy periods and falls when the area quiets, the room layout, seat location, or nearby work activity may be a bigger factor than your computer.

The room seems steady, but callers hear other people

Your headset microphone may be positioned too far from your mouth, pointed toward another speaker, or replaced by a built-in laptop microphone in the call app. Use the Microphone Test to confirm which input is active, then check the selected input in the calling software too.

The reading changes when you move a short distance

Noise can vary across a shared floor. A nearby printer, ventilation outlet, hard wall, or cluster of desks may make one seat less suitable. Compare a few nearby spots before deciding that the entire office needs the same fix.

The dB number does not match another device

That does not necessarily mean either reading is wrong. Built-in microphones differ in sensitivity and processing, and a browser-based reading is not the same as a calibrated measurement. Focus on consistent comparisons made with the same device and setup. For more on the limits, see why browser noise meter readings are not exact decibels.

How to reduce noise on calls

1. Move the headset microphone closer. Keep the boom a short distance from the corner of your mouth, rather than beside your cheek or near the keyboard. Avoid placing it directly in front of your breath, which can create pops.
2. Select the headset microphone. In the call app, choose the headset as the input instead of the laptop's built-in microphone. On Windows 11, check Settings › System › Sound and review the device under Input. On macOS, check System Settings › Sound › Input.
3. Check microphone permission. On Windows 11, open Settings › Privacy & security › Microphone and make sure microphone access is enabled for the browser or calling app. On macOS, open System Settings › Privacy & Security › Microphone and allow the app you use for calls.
4. Adjust noise suppression carefully. If your call app has noise suppression, try its normal setting and ask a colleague to confirm whether speech stays clear. Strong filtering can cut off quiet words, so do not assume that the most aggressive option sounds best.
5. Reduce nearby sources where possible. Move a rattling fan, desk phone, or printer farther away if your role allows it. Ask nearby coworkers to keep conversations away from active call stations, or move to a less busy seat if one is available.
6. Raise persistent room problems with a supervisor. Share repeated readings with the times, locations, and conditions. A supervisor or facilities team can investigate ventilation noise, equipment placement, seating layout, or suitable acoustic dividers.

If the microphone input level itself is unclear, repeat the test with one microphone at a time. The microphone position comparison guide can also help you check whether placement changes what the mic picks up.

When the headset may be the problem

Test the same headset on another computer, then test a known-working headset at your workstation. If your headset picks up unusually little of your voice or cuts in and out on both computers, inspect its mute switch, boom connection, and cable. Replace or report it if the problem follows the headset. If several headsets pick up the same room noise, focus on placement, app settings, or the office environment instead.

Use readings as comparisons, not a safety rating

A browser noise meter can help compare places and moments using the same microphone. It cannot certify that an office meets an exposure limit or replace a workplace assessment with calibrated equipment. If workers have concerns about exposure, discomfort, or hearing safety, ask the employer's safety contact or a qualified professional for an appropriate assessment.
