That is as expected.
In fact the best way to build a recording studio is inside an airtight
concrete box suspended on springs and lined with the equivalent of egg
boxes - if you want complete isolation and totally anechoic, which isn't
ideal for many recordings.Will stop the neighbours complaining about the
noise tho.
Concert halls are carefully tuned with multiple reflective surfaces to
get a pleasant reverberation.
