As it is too noisy, I can't hear you.

In this kind of construction, "it" represents an understood concept. Wherever the speaker may be is too noisy.

* As it is too noisy, I can't hear you.*

Thank you for your help. In this case, because there is no context, is 'it' an impersonal pronoun without referring to anything?

"It" is an indefinite pronoun. Of course, there's a context. We assume the listener knows why the speaker claims the noisy conditions.
Thank you.

e.g. I don't like that restaurant because it's too noisy.

(In this sentence, 'it' refers to 'that restaurant.' Am I right?)

e.g. There must be a fight going on outside. It is way too noisy.
(In this sentence, does 'it' refer to 'a fight'?)
Yes, to both of your questions.
