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) — July 2026.

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.

Why this works: Teams filters non-speech sound — fans, typing, a barking dog — before it leaves your machine. When it doesn't: if the toggle is missing or locked, your admin policy or hardware is the reason — see our greyed-out fixes.

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.

Why this works: the in-meeting panel writes the same setting as Devices, so a mid-call fix is also a permanent one. That persistence is easy to forget when you later want music to pass through — turn it back off deliberately.

If the noise persists

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.

3. Know the levels if you're on classic Teams

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.

Why this works: the levels trade fidelity against filtering exactly like Zoom's do. If you've moved to new Teams and miss Low, that's not you — the redesigned client consolidated the levels, a change Microsoft's own forums field questions about weekly.

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.

Why this works: ordinary suppression deliberately preserves anything that sounds like speech. Voice isolation matches audio against your profile instead. When it doesn't: availability depends on your organisation's policy — if you don't see it, your admin hasn't enabled it.

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.
