A/C sound insulation?
PO had a 16k btu a/c installed in* the aft hanging locker of my MT34. One air outlet into the salon. Probably not optimal. *
After it crashed, (probably early 90's installation) rather than trying to get it repaired I installed a new, bigger a/c unit last year (20k),* and ran additional ducts so that it could put more cold air* both in the aft cabin and forward. * It's great for cooling, but the Adm. complains about the additional noise, and* it's in our sleeping quarters.
I think if I install some sound-baffle insulation inside the locker it'll* help.* Any thoughts on soft foam vs rigid foam, or any other products that'll work?* I am thinking that I can "liquid-nail" it to the inside of the locker on the aft side and the door.
I* also plan to put some rubber insulation of some sort* between the shelf and the base of the unit, so any thoughts on that aspect will also be welcome.*
