Question

Dolphins, bats, and other animals use echolocation to determine the location of objects. How do blind people use echolocation to detect objects in their environment? What types of technologies and tools would be helpful?

Answer 1

Answer: Clicking sounds and clicking tools + hearing devices to help hear the clicks in loud situations

Step-by-step explanation:

Some blind people have developed the ability to make clicking noises, either with their mouth or a clicker, and they can listen for the sound of it bouncing off objects around them. Based on the tone, volume, and depth of the click, these people can tell the distance, size, and sometimes material of an object. A clicking device would be a tool that is helpful, as well as any hearing aid that could allow the wearer to hear the clicks better or clearer in a loud environment. (Note: the sound could be anything. It does not have to be a click. Whistles, beeps, chirps, and other sounds also can work for people.)
