In the new Teams client: click Settings and more (…) → Settings → Devices and turn on the Noise suppression toggle. In a live meeting it's under More actions (…) → Audio settings. Suppression is on by default and your choice carries over to the next meeting — the classic client's separate Auto/Low/High levels have been folded into a simpler control in new Teams, which is why most screenshots online no longer match what you see.
Menu paths checked against Microsoft's official Teams documentation (new Teams client, Windows & Mac).
1. Turn it on in the new Teams client
The redesigned client moved audio processing into Devices:
- Click Settings and more (…) next to your profile picture, then Settings.
- Select Devices in the left rail.
- Under your microphone options, switch on Noise suppression.
- Close settings — the choice is saved and persists across meetings and calls.
2. Change it during a meeting
Discovered the problem mid-call? No need to drop:
- In the meeting toolbar, click More actions (…).
- Choose Audio settings.
- Flip Noise suppression on — it applies immediately, and the setting sticks for your next meeting too.
When Teams's filter isn't enough
Teams can only clean audio inside Teams. If your environment is genuinely loud — street noise, kids, a mechanical keyboard — a system-level tool like Krisp filters your microphone before any app hears it, in both directions, and its 7-day free trial (no card required) is enough to tell whether it beats your in-app settings.

Organisations still running the classic client get the older four-way control under Settings → Devices → Noise suppression:
- Auto (default) — Teams picks a level based on what it hears; best for most rooms.
- High — suppresses all background sound that isn't speech; the choice for loud environments. Needs a machine that supports it.
- Low — trims persistent low-level noise like a fan or air conditioner while touching little else.
- Off — no filtering; the right setting only when you want music to be heard.
4. Try Voice isolation for the harder problem
Noise suppression removes non-speech sound. For other people's voices, Teams has a separate feature — voice isolation — that learns your voice and filters the rest:
- In Settings → Devices, look for Voice isolation under the microphone section.
- Follow the one-time voice enrolment prompt to record your voice profile.
- Enable the toggle; Teams now prioritises your enrolled voice on calls and meetings.
Still not fixed?
- Toggle missing entirely? Web Teams in a browser doesn't expose it — use the desktop app.
- Setting locked? Admin policies can pin suppression on or off org-wide; ask IT before fighting it.
- Music being destroyed? That's suppression doing its job — turn it off for performances, on for meetings.
Frequently asked questions
Does noise suppression work on calls as well as meetings?
Yes — the setting applies to both Teams calls and meetings, and a change made in either the Devices settings or a live meeting carries over to the next one.
Why don't I see Low/High options anymore?
The new Teams client consolidated the classic Auto/Low/High/Off levels into a simplified control. If you specifically need the old behaviour, it only exists in classic Teams — otherwise leave the new toggle on and let it manage intensity.
Does Teams suppression remove background voices?
Mostly no — voices are speech, which suppression is designed to keep. That's what the separate Voice isolation feature (with voice enrolment) is for, where your organisation makes it available.
How do I turn off noise suppression in Teams?
In the new Teams desktop app, go to Settings and more (…) → Settings → Devices and switch Noise suppression off. During a meeting, open the dropdown arrow next to Mic and toggle Noise suppression off there, or choose Background noise only if you just want to stop voice isolation. The choice carries over to your next calls, so switch it back on afterwards.
