Being able to hear and be heard clearly in digital meetings is crucial for smooth collaboration. Recently, an independent study from TestDevLab was published, comparing the audio quality of Microsoft Teams with three other well-known communication platforms. The focus was on two key areas: echo reduction and noise suppression—that is, how well the apps can dampen echoes and background noise without negatively affecting the voice.
Microsoft Teams Stands Out in the Tests
The study shows that Microsoft Teams consistently performed best when it came to both reducing echo and filtering out disruptive background noise. What is particularly highlighted is that Teams managed to combine effective noise suppression with maintained voice quality. This means that meeting participants in Teams generally experience fewer distractions and clearer conversations, even when several people are speaking at the same time or when there is significant background noise.
Other platforms were also able to improve sound quality compared to a completely untreated call, but it was mainly in more challenging test scenarios—such as double talk (when several people speak simultaneously) or varying echo delays—that the differences became clear.
Tests Conducted in Realistic Environments
An important aspect of the evaluation is that the tests were carried out both with human listeners and automated analysis tools according to international standards. Example test situations included office environments with background chatter, traffic noise, or keyboard typing. In all cases, Teams received the highest ratings for both speech clarity and the amount of residual background noise. The results indicate that Teams’ audio management is robust even under stress and in environments where sound quality is often compromised.
What Does This Mean for Your Organization?
For organizations that rely heavily on digital meetings via Microsoft Teams, these results could mean fewer interruptions, reduced listener fatigue, and fewer misunderstandings due to poor audio—especially in hybrid and remote work settings. At the same time, the study shows that other leading platforms have also made significant advances in audio improvement, making the basic quality high today regardless of the tool chosen. The most noticeable differences occur primarily in challenging meeting situations.

Tip: If your organization experiences recurring audio problems in digital meetings, it may be worthwhile to evaluate which settings and devices you use together with Teams or other platforms.
