Should You Add Sound to Your Infographics?
Infographics are, of course, a visual medium, but adding sound can add a whole new dimension to your infographic project. In coming years, sound will most likely become a more common feature, increasing the interactive appeal of some graphics.
Sound in infographics can be as simple as a background audio file of instrumental music.
Do not simply upload any old song into your infographic! You don’t want to violate any copyright laws. Seek out stock audio services, akin to stock photo services, that supply safely usable files. If you plan on releasing your sound infographic to the public, buy yourself a copyright-free audio file. Here are a few sites to check out:
Adding sound also opens the door to some really creative treatments. For example, you could have a highlight feature that highlights text as the voice reads it. You could also tailor the sound specifically to the information you’re showcasing.
For example, say you’re creating a graphic on the ten countries with the highest bread consumption. You could record, “Pass the bread, please” in ten languages. When readers hover a mouse over say, Italy, they would hear that phrase in Italian.
Sound does create a few potential complications. Remember that some people might be reading your infographic in a public place and won’t want to run the sound file. Adding features also requires you to be extra careful about technological compatibility.
