Put a custom class on a custom css file.(From master page settings > Alternate css you can point to that additional file)
.hiddenPageTitle {display: none;}
then only on that specific page use a piece of script to add that class to page title. Could be in a script or content editor, or if you have too many pages and you have a way to identify the page from it's type you can wrap it into an if block and add to master page. (You also will need JQuery to use the script below)
$( "#pageTitle" ).addClass( "hiddenPageTitle" );
Hope this helps.
