Remove static and Amplify voices

It's true that the nois is just way to high in the mix and there is no dialogue to be heard and isolated over this sound. I checked by normalizing the audio but it just sounds like white noise.

Sorry - not a chance in hell with this. The AC gets a lot louder below 1kHz, and above that there is no discernable content. Please do not believe what you hear on CSI - it's absolutely not real. There are absolute limits on what can be usefully extracted, and this is well below them.
