Resumen de How blind people can 'see' like bats
Now Lore Thaler of Durham University, UK, and her team have carried out the first in-depth acoustic analysis of mouth clicks. They worked with Kish and two other blind echolocators. The clicks turned out to be highly focused sound waves emitted in a 60-degree cone shape, compared with 120 to 180 degrees for typical speech. Unknowingly, the echolocators had worked out how to "point" their clicks towards the space they were sensing, says Thaler.
