Post 3 Echolocation

In the book See What I'm Saying The Extraordinary Powers of Our Five Senses, a man named Daniel Kish was never able to see. At four months he was diagnosed with retinoblastoma in both eyes and then eventually had both eyes removed. Kish does not let that stop his independence. He became an expertise with echolocation. Echolocation is the location of objects by reflected sound, they are particularly used by animals such as dolphins and bats. This allows Kish to know how close or far away an object is to him by using a clicking sound. By the age of 7 he was able to ride his bike and roller blade like any other child. Here is a video of Kish explaining about echolocation.


  1. I never thought humans had the ability to detect objects in their environment by sensing echoes from those objects, by actively creating sounds. Echolocation is an intriguing communication method that we should all take some time to read more into and try to learn since we all have the ability to do it but just need to strengthen our skills and notice we have these abilities.

  2. I enjoyed reading your post about echolocation! It is so interesting how even though someone is blind, they can still get around due to hearing objects.

  3. Thank you for sharing that video, I will definitely give it a watch! I also thought echolocation was a very interesting concept, something I really want to look more into. Daniel Kish's story is very inspiring.
