How to remove a low-pitched background noises ?

Hello, 

I have recorded myself and I am able to reduce the background "wind", but my microphone has recorded little "booms" when I talk, and I can't isolate them. It's pretty unpleasant to listen. I have found tutorials to remove bird sounds for example but these low-pitched "booms" don't appear distinctly on the spectral frequency display. Do you have any solution ? 

Thanks
