Thank you for your comments. I am sorry that you cannot immediately find the study environment you want. The library has a variety of study spaces so by definition some areas will always be noisy. There are no silence requirements enforceable for these areas.

There are plenty of spaces that offer silent study namely the Silent Study Rooms on levels 4, 5 & 6. These have the specifications noted in your comments. Please relocate to one of those rooms. I am sure they will meet your study style.
