The researchers in the large anechoic chamber Studies on echolocation, the ability of humans to detect (and in many cases, dodge) objects by detecting echoes from these objects, started in the 1950s. To continue and add to the findings of these studies, researchers at the University of Southampton conducted a series of experiments to find out whether blind people can use the same tools/techniques used by bats and dolphins to detect objects which would help them navigate in their immediate surrounding. Humans, bats, and dolphins have a common set of specialized brain processes that can locate the source of the sound. The researchers, including Daniel Rowan, used Diane Marks (among other blind and sighted volunteers) for their experiments. Diane lost her sight 16 years ago. Bats and Dolphins are well known to use echolocation to navigate through the dark and the ocean very effectively. The purpose of Rowan’s experiments was to determine how effective humans can be in learning the same techniques that bats and dolphins use. For these experiments, Rowan and his team built a special large anechoic chamber to demonstrate that both blind and sighted people can use sound to locate objects (see video for details). They also determined [...]
