Perhaps you should try some spelling variations:
synchronized » synchronizer, synchronies, synchronizing, synchronizingd
synchronisms » asynchronisms, synchronies, sincronismo
synchronous » synchronies
asynchronous » asynchronies, asynchronisms, synchronies
synchronize » synchronizing
sound » found

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((synchronized OR synchronisms) OR ((synchronous OR asynchronous) OR synchronize)) sound~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((synchronized OR synchronisms) OR ((synchronous OR asynchronous) OR synchronize)) sound".
• Adding a wildcard symbol may retrieve word variants: ((synchronized OR synchronisms) OR ((synchronous OR asynchronous) OR synchronize)) sound*.
