FOTRSU Ambient Sound Effects

I've just started playing SH IV with the Fall of the Rising Sun Megamod. I am really enjoying it except for the obnoxious ambient sounds that can be heard when in the command room. It consists of whistling, aquatic life, loud creaking (even on the surface), and random zoom sounds. It's quite annoying and I was wondering if there was a way to turn it off. I appreciate that the modders wanted to include some sounds to enhance but its way more annoying than immersive. Thanks!
