How blind see with his ears ?

When dealing with the blind on the basis of a professional or social relationship, one wonders about the impact of blindness on the senses, behaviors, and perceptions of the blind. And that any attempts to imagine the effect of blindness by closing the eyes are not sufficient to know the impact of this problem for those who were born with it, as it seems impossible for a sighted person to know the meaning of blindness.

The benefit of hearing is limited to understanding and oral information. As for the distinction of space, it is by touch. The senses of controlling the trend play a big role in it, but distinction by touch does not have a serious effect unless there is direct contact between the blind and the same thing, and this limits the value of this sense, there are things that cannot be touched like clouds, horizon and the sun, and there are things that are either very small or Too big as the mountains do not touch as much as is seen.

It is clear that looking is a guide to touch and touch is a guide to feeling something because the eye is always open and ready to receive various influences from the outside world, whereas it is necessary to touch in practice in order for a person to get some ideas about the tangible thing, because touch allows understanding of characteristics that he cannot look to distinguish such as The heat, the characteristics of the outer surface.

And the color distinction are a visual property due to the influence of the retina, and therefore blind people cannot distinguish the color despite the presence of alternatives to colors or even other senses, as the blue color is related to the blue sky. It can also be said that spatial perception, perceptions and color experiences are areas of difference between The blind and the sighted.

A person draws his information through his senses, in this order from the lowest to the highest:

Taste, smell, touch, sight, and hearing

This means that the information that it acquires by hearing is more than that which is acquired by sight, and the researchers emphasized that the person hears more than he sees in many stages. This emphasizes the importance of the sense of hearing and that it precedes the sense of sight in obtaining knowledge. Studies have shown that there is no difference between the ability of the blind and the ability of the sighted to auditory perception but must take into account the characteristics of learning and educational position and the relationship between the ability of the blind to auditory absorption and academic achievement a strong and direct relationship.

How blind see with his ears ?

 The sense of hearing is one of the activities of the senses at the blind because it depends on it, it depends on it in all its perception of what is around it, as well as in obtaining information about the things that exist in its environment, and the blind can form a mental image of the various events and situations, as studies indicate that the blind depends On the ear to know the distance, direction, and different positions.

The importance of the sense of hearing was confirmed, and it precedes the sense of sight in obtaining knowledge. The strength of the hearing sense of the blind is due to the fact that this sense develops gradually and not automatically due to the dependence on it because of the lack of references that Braille needs, which makes it dependent on tapes or other people who read everything that wants to lead to the development of the sense of hearing.

There are a set of ideas that contribute to developing the skill of listening for the sense of sight, namely:

Starting with clear voices, the difference between their presence and their absence is clear:

Use dolls, musical instruments and utensils to provide familiar sounds, and enhance the blind’s interest in sound.

Repeat and repeat sentences, follow verbal directions, and repeat musical rhythms.

– Training to save and retrieve songs and stories

Training to classify things after learning their names.

Sensory perception means the interpretation of sensory alerts received by different sense organs, and giving meaning to them according to the individual’s previous experience of these alerts. 

The sensory perception process begins with an alert source through the energy that affects the sensory cells that receive that stimulation, which varies from one sense to another where the visual sense is affected by light waves, the sense of hearing is affected by sound waves and the sense of smell and taste are affected by chemicals while the skin cells are affected by pressure and mechanical movement Then the sensory cells then convert these stimuli into nerve impulses that are transmitted by the nerve cells to the nerve centers in the brain where cognitive processing takes place. Sensory perception also occurs with a certain amount of stimulating energy called absolute eyes. Minimum necessary to alert a member of a particular sensory power of the individual.

The blind person’s awareness depends on his use of other senses such as: the sense of hearing or touch. Therefore, the blind suffer from a lack of experiences that they get and the hand is at the blind for a future member and source at the same time.

Therefore, hand training is of great importance for the blind as research and exploration tools gather things When the blind is in the hand and thus the hand affects the social and economic life fundamentally and plays a major role in discovering the blind around it and realizing the sizes and shapes and distinction by touch does not have an effective impact unless there is a direct contact between the blind and the same thing. 

The value of this sense may be limited by the presence of difficult objects to touch, such as large objects such as mountains and trees, or small ones, such as insects. 

Through the sense of hearing, the blind can learn to weigh the personality of the individual who stands before him, and through extensive experiences he can teach the tone of sound that accompanies the psychological state related to various degrees of emotions, depending largely on his intelligence, experience and the number of his experiences in contact with people. He can also distinguish between birds by simply hearing their sound, and between trees by simply hearing the sound of the breeze passing through its leaves, and he can also enjoy listening to music.
