silencing a home AC unit?

thanks for all the advice guys
I had to run into Chicago, so I didn't have time to stay on top of it

I pulled the metal off but that didn't do the trick (there was also a some nice thick particle board underneath)

ill have to remove the wooden frame that held the roof up to see if it is possible to put some rubber underneath

@dukeboy_318 the compressor is definitely within 6 inches of the house
even if I felt comfortable moving it, I don't know if the wires/pipes/hoses would reach, and it would require pouring a new pad (which would then be on the lawn)

as for moving the mother in law to another room...I just don't have any more
the only other bedroom on the ground floor is my oldest girls room (with the loft) and I doubt she would want to give it up
beside, those two rooms are right next to each other, and just as close to the A/C

there is the "option" of her moving into her "living room" which is kinda like a den, off the back of the house, but she didn't want to

all other bedrooms are either downstairs or upstairs (our masterbedroom) and that's just not a good option at her age
