At this time of year, many of us are poring over guidebooks to choose a destination for our summer vacation. In travel guides your will find descriptions of beautiful vistas and iconic architecture to look at - but very little about sounds. What a shame.There is so much to delight the ears when we bother to open them. Take the dome of St. Paul's Cathedral in London. A beautiful sight, yes - but an incomplete experience if encountered solely with your eyes. When you whisper into the curved walls, your voice skims around the inside of the dome and is clearly audible to others on the opposite side.. We are entering a golden age for sound tourism - one driven by consumer electronics.. Our ears play an immensely important role in how we perceive our environment. Show less «
