Hi @Dean MacGregor,
Good day! Thank you for reaching out to Microsoft Q&A forum and sharing the detail.
According to your concerns, I completely understand how valuable individual volume control would be in larger meetings, and I agree that this feature could greatly enhance the user experience in Microsoft Teams, especially when varying microphone levels can be distracting or disruptive.
At this time, Microsoft Teams doesn’t support per-participant volume adjustment on the client side. Each participant manages their own mic volume, and while the “Automatically adjust mic sensitivity” setting helps normalize levels, it doesn’t allow you to fine-tune others’ volumes locally.
I understand the importance of this feature and agree it would be a meaningful improvement, especially in large meetings. Although it’s been raised before, your feedback is still incredibly valuable. Microsoft prioritizes features based on user input, so I strongly recommend submitting or upvoting the idea on the Teams Feedback Portal: Microsoft Teams · Community 
The more feedback and votes a request receive, the higher the visibility it gains with the Teams product team and your voice can help influence that.
Thank you again for sharing this, I truly appreciate your voice in helping shape the future of Teams. If there’s anything else I can help clarify or support you with, please don’t hesitate to ask.
