We can discuss the right use and effectiveness of sound on websites, and in most cases we will hear background music and interface sounds, but the Building Sound website is using sound in a way I have never seen (or heard) before!
As we mouse over the colored horizontal bars on the website we hear the name of each menu item. The length of the bar gives an indication of the length of the item we will hear when we click on it. It is fascinating to see how easy it actually is to navigate this site without any textual information.
The implementation is done well, although the site leaves some things to be desired. What if we surf the web with the sound turned off? And to be honest, there is a lot of background noise in the files and the intonation of the voice we hear is not very compelling. Nonetheless, a great idea.
