What is FlashSonar?

FlashSonar™ (our advanced and activational form of active echolocation) is a blind person’s developed perceptual ability to determine where and what things are around them, and how to effectively navigate and interact with these surroundings.

This is done by a person making a discrete, quiet tongue click, which allows the ear and brain to work together to construct a 3-D image from the reflected echoes of objects.

It is like seeing with sound, as if with dim flashes of light, but using flashes of sound instead. Once developed, this image or spatial understanding is a very powerful addition to a blind person’s travel competence and to fostering feelings of confidence about making friends and participating in social activities.

FlashSonar training inspired the phrase ‘Our Vision is Sound™’, which is what many of our students use to simply explain their awareness and deep connection with the world.

I have heard that not everyone can learn FlashSonar and that some people are just born with the ability. Is that true?

All humans are born with the ability to use FlashSonar if they can hear. Sighted people can even learn basic levels of FlashSonar perception within minutes of guided exercises. The trick is training the brain to know what to listen for and to know how to process that information.

People around the world of all different ages and backgrounds have learned FlashSonar and use it to be more efficient at self-orientation in new places. The common factor for success among our students is their motivation for a better life experience and their frequent opportunity to practice and apply the skills.

Why teach active instead of passive echolocation?

We teach the active click for a number of reasons.

First, active echolocation gives control to the user to acquire a vast amount of information in any location at any time. Biosonar scientists refer to active echo calls as “interrogating the environment”. Indeed, we often explain to our students that they are using an echo language to converse with the environment.

By strategically clicking, we ask the questions, “Where are you” and “What are you”, and surfaces throughout the environment answer these questions for those who understand the language of echoes.

Secondly, the process of actively clicking give a blind person more control and thus empowers the development of internal attitudes such as confidence, maturity and the ability to socially engage all people. These internal qualities are very important for navigating everything in life, from school to work to romance.
