When I’m sitting in the orange zones in the later afternoon I find the noise level intolerable, to the point where my noise reduction earphones do not block out the sound of people talking. It is especially bad on the 4th floor near the elevators. I have often seen members of staff moving around the area and they never say anything. How are we supposed to take the advice of complaining to staff seriously when they do not even take the initiative on their own?
The Library has dedicated staff members who roam the libraries assessing the noise levels. Please do continue to inform staff members when noise levels are excessive. If there are no staff members walking around, please report noise to a service desk.
