 		If you require the test to be conducted at a certain sample rate (i.e. you do not tolerate resampling of the elements to correspond with the system's sample rate), add \texttt{sampleRate="96000"} - where ``96000'' can be any support sample rate (in Hz) - so that a warning message is shown alerting the subject that their system's sample rate is different from this enforced sample rate.

 	\subsection{Loudness}
 	\label{sec:loudness}
 		% automatic loudness equalisation
 		% guide to loudness.js 
 		Each audio fragment on loading has its loudness calculated. The tool uses the EBU R 128 recommendation following the ITU-R BS.1770-4 loduness calculations to return the integreated LUFS loudness. The attribute \texttt{loudness} will set the loudness from the scope it is applied in. Applying it in the \texttt{<setup>} node will set the loudness for all test pages. Applying it in the \texttt{<page>} node will set the loudness for that page. Applying it in the \texttt{<audioelement>} node will set the loudness for that fragment. The scope is set locally, so if there is a loudness on both the \texttt{<page>} and \texttt{<setup>} nodes, that test page will take the value associated with the \texttt{<page>}. The loudness attribute is set in LUFS

+	\subsection{Comment Boxes}
+	\label{sec:commentboxes}
+	    There are two types of comment boxes which can be presented, those linked to the audio fragments on the page and those which pose a general question. The audio fragment boxes are shown by setting the attribute \texttt{showElementComments} to true of the page in question. This will then show a comment box below the main interface for every fragment on the page. There is some customisation around the text that accompanies the box, by default the text will read "Comment on fragment " followed by the fragment identifier (the number / letter shown by the interface). This 'prefix' can be modified using the page node \texttt{<commentboxprefix>}, see \ref{sec:page} for where to place this node in the document. The comment box prefix node takes no attribute and the text contained by the node represents to the prefix. For instance if we have a node \texttt{<commentboxprefix> Describe fragment </commentboxprefix>}, then the interface will show "Describe fragment " followed by the identifier.
+	    
+	    The second type of comment box is slightly more complex because it can handle different types of response data. These are called comment questions because they are located in the comment section of the test but pose a specific question.
