Thanks for your suggestion. We do have staff walk through all of our spaces on a fairly regular basis, but can't be everywhere at all times.
In the future, may I suggest you first ask the loud parties to quiet down, and if this doesn't work please send an email to firstname.lastname@example.org or complete the form which can be found at https://library.mcmaster.ca/forms/report-noise-quiet-area
These get sent directly to staff who will come speak to the chatty groups. Please make sure to give us some indication of where the problem is so we don't waste time trying to figure out where they are.
Hope this helps!
