Regulations Governing Personal Behaviour in the University Library (Mills, Innis & Thode)
NOISE: Loud conversation, offensive language, rowdy or disruptive behaviour is prohibited in all library spaces. During Exam Periods, designated Quiet Study areas will be established (Mills: 3rd - 6th Floors; Thode: 1st and 2nd Floors; Innis: Back room excluding group study rooms.)
Notice this reg applies to all spaces. If the university doesn't want to enforce it then students should be able to enforce this reg with tasers.
There is a mandatory fee for athletics. Then you can opt to pay an extra fee if you actually want to use the facilities. Why not have a library where you can opt in and pay a fee which will be used to hire security who will take a zero tolerance approach to students who don't follow the regs regarding personal behaviour in the libraries. Issue them with decibel meters and throw out the offenders. If they resist, tase them. Or for those with an eco bent, the university could make use of the third R and grind them up to make chilli in The Commons.
The precedent for charging an extra fee to use a university facility has already been set.
If you are, or can become a morning person, the libraries are pretty quiet for the first hour or so after opening.
The Health Science library carols on the ground floor farthest from the stairs are pretty quiet.
