     Where is that noise coming from? Not sure? Try living with your eyes closed for a few years.
     Blind people are better at locating sounds than people who can see a new study says without the benefits
of vision the ears seem to work much better.
     Previous studies have shown that blind people are better than others at reaching out and touching the
sources of sounds that are close by. Researchers from the University of Montreal wanted to see if blind people
were also better at locating sounds that are far away.
     Twenty-three blind people participated in the study. All had been sightless for at least 20 years. Fourteen of
them had lost their vision before age 11; the rest went blind after age 16. The experiment also included 10 people
who could see but were wearing blind-folds.
     In one task volunteers had to pick the direction of a sound coming from about 3 metres away. When the
sound was in front of them or slightly off center in front both groups performed equally well.
     When sounds came from the side or the back however the blind group performed much better than the
blindfolded group. The participants who had been blind since childhood did slightly better than those who lost
their sight later.
     Recognizing the locations of distant sounds can be a matter of life-or-death for blind people say the
researchers. Crossing the street for instance is much harder when you can't see the cars coming.
     Still the researchers were surprised by how well the blind participants did especially those who went blind
after age 16. In another experiment the scientists also found that parts of the brain that normally deal with
visual information became active in locating sound in the people who were blind by age 11. These brain parts
didn't show sound-location activity in the other group of blind people or in the sighted people. The scientists
now want to learn more about the working of brains of "late-onset" blind people.
