Loud sounds help to improve hearing, say scientists

Experts from the University of new York conducted an experiment on rats. Animals include loud sounds and as reinforcements reflex was given food. At the same time, there is a blue spot stimulation of the brain, the area responsible for the formation of norepinephrine, reports Zee News.

Two weeks after the start of the experiment, the scientists lowered the volume of the played sounds. In the next two weeks, the activity of the blue spot remained at the same level, and the soft sounds of the animals were perceived quite well. In normal condition the rats to the sounds of such a volume does not react.

Blue stain, scientists believe, is the "amp sound". Have this structure in humans. Perhaps this experience will help in the development of methods to improve hearing in people.
