The noise in the library is too loud. How can I study with peace of mind?
You can buy industrial earplugs online. They are very easy to use. They are usually sold blindfolded. I bought it, but I can't hear anything. Also, why is the library loud? Is there any noise? In the past, our university library only had the sound of turning pages. As long as you talk, all eyes will stare at you and kill you with their eyes.
