How do I the change the settings in the AudioReverbZone component using c#?

I am working in C#, and new to this language. I looked at the scripting reference, but it was no help. I have an AudioReverbZone component attached to my First Person Controller. I want to change the roomLF value of this AudioReverbZone based on the position of the player. QUESTION: ***How do I access the AudioReverbZone, and how do I change its settings?***
