Do I need sound?

To access and get the most out of our free demonstrations, free quizzes and our online energy course, you will need to have a computer with a sound card. 

Please note: You will still be able to complete our online energy course even if you don’t have sound as it is fully supported by a detailed transcript.

Because the audio plays automatically when you open a demo, quiz or course, if you take a course in an open work area, you should mute the audio or use headphones as the sound may disturb your colleagues.
