Beginner Echolocation Lesson #8 - Seeing Right and Left



To begin determining direction and placement of objects around you, one of the skills you will need is to be able to differentiate between objects to your right and objects to your left.
  1. With a partner, start by using a dinner plate or similarly sized rigid sheet of plastic, metal or wood and have your partner hold it up to one side of your head. Perhaps not directly on the side, but out in front of you to the right or left at about a 45-degree angle. 
  2. If you are sighted or partially sighted, of course you'll need to close your eyes or wear a blindfold.
  3. Instruct your partner to move it to within 12 inches of your face, and then without notice, remove it from your view. Keep clicking or performing whichever signal works best for you.
  4. For this exercise, the flat surface of the object should always be facing directly toward you. This will ensure that the strongest, clearest response is reflected back toward you. 
  5. It is important that the object you are using does not make any noise of its own, such as the pages of a magazine. It’s also important that the person holding the object does not scratch or manipulate it in such a way that makes any sound. This will defeat the purpose of the exercise. 
  6. Once you can clearly tell when the object is present and when it’s not, try it on the other side. 
  7. Get used to both sides and then have your partner surprise you. After a short period of training, you should be able to easily determine where the object is.

Good, you're doing well, but it's a little more complex than the way you've described it. If you're able to determine which side the sound is coming from consistently, then you're off to a good start and you can probably move on to try some other exercises, but make sure to practice this a lot and get very comfortable with it. Come back to this lesson even if you decide to move on just to make sure you are confident with it. I plan to post some other lessons here shortly that will be a big benefit to you as well. You can also get a lot of other lessons from the book! Keep it up!

You're welcome to try whatever you feel comfortable with. I've just published another lesson that you will probably be interested in. Lesson #9 helps you to improve the resolution of your vertical axis of perception.
