How effective audio might be in the e-learning environment:

 Audio is most effective in the e-learning environment when the graphic on the page is the main focus and the text is intended to be presented simultaneously. According the Clark and Mayer (2008), e-learners experience virtual overload when they are forced to process graphics and written text simultaneously. Times when audio is not effective to use in the e-learning environment include when technical demands are not able to be met due to bandwidth, headsets, and sound cards. Adding sound can also add an unreasonable expense due to needing to update changing information. Audio is not necessary during times when there is not a graphic or written text included in the portion of the information.
