Discussion Interaction between Zoom and Physical Attendees.

Should be simple solution.  During a structured Zoom meeting, physical attendees number approximately 30.  Joined by Zoom attendees (approx. 10).  The Zoom attendees have trouble hearing what some of physical attendees are saying where the physical attendee might be about 15-20 feet away from the computer being used to Host the Zoom meeting.  Room size is about 75' by 30'.  Is there a practical answer without asking physical attendees to keep step closer to the laptop being used and also not having wires running to microphones (ie running on blue tooth).  Thank you.
