Remove static noise from MP4 files

Hi,

I need someone to remove the static noise from 17 x MP4's. The lengths of the videos vary from around 3 minutes to 18 minutes. The static sound is the same frequency throughout each of the video's so would along need that remove - no other editing.

Link to files is here:
