    Pressure means nothing, make sure it's correctly charged and not slugging liquid and then put a sound -deadening blanket over it if it doesn't already have one.
    If everything was always done "by the book"....the book would never change.

    you can put a sound blanket around the sides of the scroll but do not cover it

    If its a Copeland Scroll then Copeland makes a custom blanket for it.

    Shoot it. I've never seen a blanket make even a slight difference in noise reduction.

    The first thing I did to my YRA heat pump 10 yrs. ago was pull that heat trap off the scroll.

    Sound blankets do reduce noise but if you have a nosiy compressor to start with they wont do much. They reduce the hum from the compressor. They are not a heat trap since the compressor is cooled by refrigerant not air. Airfow around a compressor has no effect on cooling, otherwise the compressors would have fins like the head of a motorcycle.

    The real problem needs to be addressed which may be charge related, airflow related, oil return related, non condensibles or a damaged compressor. Most often the compressor is changed out of ignorance but the noise returns because the real problem was never resolved and by replacing the compressor inadvertantly the non-condensibles issue gets taken care of and the oil is now doubled in the system which allows the poorly run refrigerant lines which trap oil to now flow it.
