What do we call a discussion among specialists when there is no audience participation?

A discussion among specialists without audience participation is best described as a panel discussion. In this format, experts share insights, perspectives, and their expertise on a specific topic while the audience remains passive, listening to the conversation rather than actively engaging in it.

This structure allows for in-depth conversations among specialists who are often selected for their knowledge and experience in the field. Their interactions can often lead to a richer exchange of ideas and insights that might not occur in a more participatory setting. Such discussions are particularly valuable in complex topics where the audience benefits from the expertise of the panelists and the depth of conversation generated among them.

The other options typically involve different levels of audience interaction. A roundtable discussion tends to be more collaborative with input from all participants, including those from the audience. A forum usually invites broader community participation and public engagement. Meanwhile, a symposium involves multiple presentations and can sometimes include audience questions, suggesting a more interactive format than a panel discussion.
