A Person Praying in a Noisy Place

How should a person praying in a noisy place pray? Does he need to hear his prayer despite the noise?

One should raise their voice until they can hear themselves. There is a question whether, when there is a loud noise, one must also raise their voice to hear themselves, or if it suffices that without the loud noise they would hear what comes out of their mouth. For example, during the reading of the Megillah when Haman is struck and an individual recites the verses, must they raise their voice until they hear themselves? Evidence can be brought from this week's Torah portion about the frogs, where the verse states, "And Moses cried out to the Lord concerning the frogs...", whereas in other plagues it states, "And Moses prayed to the Lord", and the Siftei Chachamim explains that here it says "cried out" to overcome the sound of the frogs croaking loudly.
