Suppose you have two stationary people, A and B, who are equally effective in terms of hearing ability, and A emits a sound that is heard by B at a certain intensity. If they remain stationary, and B makes the exact same sound, does A hear the sound at the same intensity as B?
Yes, both of them will hear the sound with same intensity. From your description, their situation are completely symmetric, so you can simply relabelled them from A to B, and B to A. Hence the results.
