     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.

1. The recent study shows blind people are better at telling ____. 

A. the sources of loud sounds

B. the locations of distant sounds

C. the direction of sharp sounds

2. Which would be a proper title for the passage?

A. A Research on Blind People

B. Where is That Noise Coming from?

C. Hearing Better in the Dark

D. What If Living without Your Eyes?

3. If people were asked to tell the direction of a sound from the side, who would perform best?

A. Those who are blind.

B. Those who have gone blind since children.

C. Those who went blind at age 16.

D. Those who are blindfolded.

4. Which of the following is true according to the passage?

A. Whether to be able to locate the sounds can be of vital importance for the blind.

B. All the volunteers in the experiment are sightless.

C. All the participants did equally well when picking sounds from whatever direction.

D. The later people become blind, the better they can perform in telling the direction of sounds.
