When the sound reverberates or Echo, it helps them to information about the distance, density and dimension of any object. The reflection of echo can help us to know about the distance of object.

Which can help them to walk. the reflection sound also give information about the structure of object like large small soft etc. The acoustic reverberations give us a mental image of space and help us navigate. If you learn it, it is almost impossible to bump into a wall. Through this sound blind person can create mantle picture which can be help the blind person to walk.

It is more convenient to use a cane instead of clicking your tongue towards the ground. You can also clap in traffic or noisy places. Combine all the techniques intelligently,” he said.
