Perhaps you should try some spelling variations:
decreased sound » decreased bone (Expand search), decreased and (Expand search), decreased food (Expand search)
with decreased » with increased (Expand search)
decrease that » decrease the (Expand search), decrease at (Expand search), decrees that (Expand search)
that decrease » that increase (Expand search), that increases (Expand search), not decrease (Expand search)
decrease with » decreases with (Expand search), increase with (Expand search), decrease the (Expand search)
sound object » sound objects (Expand search), and object (Expand search)
in decrease » in decreased (Expand search), on decrease (Expand search), pain decrease (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease that decrease in decrease ) OR ( decrease with decreased sound object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease that decrease in decrease ) OR ( decrease with decreased sound object ))*.
