Research Helps Understand the Ability to Pinpoint Object Location Using Echolocation

This is a brief article, and more importantly a video documenting some of Dr. Daniel Rowan's research in the field of echolocation.  Rowan is a lecturer in the audiology department at the University of Southampton and has been working to try to create experiments designed to quantify the subtleties and understand the usage and effectiveness of echolocation for both blind and sighted individuals.

Here is a link to the video:

In the video link below they use an "anechoic chamber" to isolate sounds for experimental purposes.  A flat object is moved from side to side to test the ability of a subject to determine it's location.  This is a somewhat fundamental test, and I would say that since it is a large flat object that the test should be fairly easy for anyone who is familiar with the use of echolocation.

I've been in communication with Dr Rowan about his research and he is a very enthusiastic person with plans to continue his research with further studies to help better understand and quantify this skill.  Perhaps in the future he will publish some studies on the more subtle aspects of echolocation, such as the effectiveness of echolocation with varying levels of background noise, or the precision of edge-finding using different frequency signals, or the precision of subjects' ability to determine object construct.

Stay tuned for more exciting things in the field of echolocation! :)

Free 10-Minute Audio Lesson: Learn the Echolocation Click

Learn echolocation clicks with a free audio lesson
Learning how to click is one of the first steps to becoming an effective echoloator. This lesson provides clicking samples of a variety of different clicks and descriptions of when they might be most useful. This lesson has been used by O&M instructors all over the world.

Despite popular belief, it's easy to make your clicking quite subtle or unnoticeable even in quiet settings. There are many different clicks for different situations. I explain all of these in great detail and give examples of where, why and when they can and should be used.
