In an effort to make the echolocation beginner's guidebook more accessible to everyone, I have recently made the book available on Audiobooks.com. The audio version of this book is read by an excellent narrator by the name of Gabriel Bush. The book is short and concise, while it's just over 2 hours long, it contains a wealth of information and has been the starting point for many blind persons on their way into the world of echolocation.
