After talking to our experts,and understanding that our idea can not be done in three days we decided to change our issue. The issue we have taken now is deafness.
Deafness is the complete inability to hear sound. Deafness and hearing loss have many causes and can occur at any age. People can go deaf suddenly as a complication of a virus, or lose their hearing over time because of diseases, nerve damage, or injury caused by noise.
Hearing loss is a spectrum with minor hearing problems at one end and profound, complete deafness at the other. Conductive hearing loss occurs when something blocks sound waves from reaching the inner ear. Sensorineural hearing loss is caused by damage to the inner ear or to the nerves that send sound to the brain. Sensorineural hearing loss is more likely to be permanent and to cause deafness. Sometimes a mixture of conductive and sensorineural hearing loss can occur.
Many different conditions lead to partial and total deafness. Ear infections, fluid buildup behind the eardrum, holes in the eardrum, and problems with the middle ear bones can cause deafness from conductive hearing loss. In rare cases, tumours can also cause conductive hearing loss — they block sound from getting into the inner ear. Birth defects and diseases passed on by genes can do this, too. Genetics is one cause of sensorineural hearing loss. Half of all cases of profound deafness in children have a genetic source.
Presbycusis, or age-associated hearing loss, also has a genetic component. It’s a condition that makes someone deaf over time as they age due to the slow decay of sensitive hair cells lining the inner ear. Aside from aging, other causes of the decay include circulatory problems, diseases such as diabetes, and long-term exposure to noise. Without the hair cells, recognizing sounds becomes difficult or impossible.
Exposure to loud noise in certain occupations from sources such as construction machinery, heavy equipment, or amplified music can cause sensorineural hearing loss in people of all ages and is the most common cause of hearing loss. Other sources of excess noise include attendance at concerts and nightclubs, and use of music headphones, household power tools, or firearms. The louder the noise, and the longer a person is exposed to it, the greater their risk of this type of hearing loss. To prevent this type of hearing loss it is important to wear proper hearing protection and avoid exposure to loud noise whenever possible.
Some kinds of sensorineural hearing loss or deafness may be caused by infectious diseases, such as shingles, meningitis, and cytomegalovirus. In childhood, the auditory nerve can be damaged by mumps, meningitis, German measles (rubella), or inner ear infections.
More rarely, deafness or hearing loss can occur suddenly. This condition can be permanent or temporary, and usually affects only one ear. The cause is unknown but may be due to viral infections, or disorders of the circulatory or immune system. The loss is potentially reversible with corticosteroid medications; however, the likelihood of recovery is lower if the loss was severe initially. Treatment is more likely to have greater effect if it is started early — ideally within a week of the loss of hearing.Hearing loss is a spectrum with minor hearing problems at one end and profound, complete deafness at the other.

Profound deafness is easy to recognize, since people will notice such a large change in hearing. Milder hearing loss may not be noticed right away, since it often comes on gradually and people “get used to it.” If you notice that you need to turn the volume up on the radio or television, have difficulty understanding conversations, or need to ask people to repeat what they say, you may have hearing loss.
Research shows that deaf people are forced to quit jobs due to inefficiency. So we are working towards a product which will help deaf people get jobs in restaurants and work efficiently in them. Below is a site that will help know more about deaf people and their work issues.
