Large Meeting = 10 or more participants. Similar to a seminar with 'speakers and audience'. Infected occupant(s) is standing and speaking 1/3rd of the time, while the other occupants are seated.
Library = All persons seated, breathing only (not talking), all the time.
Call Centre = All persons seated, all talking simultaneously, all the time. This is a conservative profile, i.e. will show an increased P(i) compared to office/meeting activity. Everyone (exposed and infected occupants) is treated the same in this model.
Control Room (day shift) = All persons seated, all talking 50% of the time. This is a conservative profile, i.e. will show an increased P(i) compared to office/meeting activity. Everyone (exposed and infected occupants) is treated the same in this model.
