It just dawned on me that I misunderstood the meaning of the question, but since I already voted.....
...naw...my room is not soundproofed, but once a year it gets better! When the "stockings were hung by the chimney with care...." The room gets tamed and the tunes sound a lot better!!
Stockings hung on the fireplace, along with an extra large wreath above the mantle really help, as do the Christmas trees next to the fireplace and in the bay window. And the yards of garland strung around helps too!
My M50s really like Christmas...they really do!
