Is the following statement accurate?

Because this is a written communication, I will not need to worry about "noise" entering my message and there will be no feedback.

No$,$ noise can enter at any point in the communication, and feedback can be given in writing or verbally, though the feedback is not always immediate.

No$,$ I will get noise because my audience might not understand what I$\text{'}$m saying, but I won't get any feedback because they're not there to respond.

Yes, there is no one standing in front of me hearing the message, so I won't get any noise or feedback.
