Questions & Answers about В такой шум невозможно работать.
Why is it в такой шум (Accusative) instead of в таком шуме (Prepositional)?
When talking about environmental or weather conditions as a backdrop to an action, Russian often uses в + Accusative. It acts similarly to "during" or "under these conditions." You will also see this with weather, like в дождь (in the rain) or в жару (in the heat). Using the Prepositional в таком шуме is also grammatically correct and focuses on literally being "inside the noise," but the Accusative is highly idiomatic for expressing that an action takes place despite or during these noisy conditions.
Could I use the perfective verb поработать here instead?
You could, but it slightly changes the meaning. The imperfective работать makes a general statement: the ongoing process of working is impossible. If you used the perfective поработать, the focus shifts to a specific result or a block of time, meaning "it is impossible to get even a little bit of work done."
Who is the subject of this sentence?
There isn't one! This is an impersonal construction built around the adverb невозможно (impossible). Because there is no noun or pronoun in the Dative case (like мне or нам), the statement is general: it is impossible for anyone to work in this noise. If you wanted to make it specific to yourself, you would say Мне в такой шум невозможно работать.
Why does the sentence start with В такой шум rather than Невозможно работать?
