Is it possible that there could be partial deaf problems to adults & Child?

I.e.  Either Left or Right Ear is defective but not both. One is able to hear only from one ear only.

Thanks & Regards,
Prashant S Akerkar

Is it possible that there could be partial deaf problems to adults & Child?

Given the use of earbuds and constant exposure to loud noises from concerts and parties, more and more adults are beginning to lose their hearing - this is referred to as age-related hearing loss ( presbycusis).

It is possible that one ear could be damaged more than the other, again due to life experiences that dictate the impact. What you're referring to is called single-sided deafness (SSD). The hearing loss is usually permanent and may be the result of a variety of conditions including (notice that those listed below are NOT congenital):

• Sudden deafness – can occur at any time, often for unknown reasons
• Physical damage to the ear
• Pressure on the hearing nerve
• Inner ear problems including infections (viral or bacterial)
• Diseases such as measles, mumps, meningitis
• Tumours in the ear or brain
• Disorders of the circulatory system
• Severe Meniere's disease
• Trauma – e.g. head injury

Being deaf in one ear presents a variety of challenges, most notably difficulty in determining the direction of sound. Another issue which affects communication is the “head shadow effect." Sounds that originate from the side of the deaf ear actually fall in the shadow of the head. Vowel sounds which have longer wavelengths may still travel from the deaf side to the hearing side, but consonants which have a shorter wavelength and carry the most meaning for speech and conversation, don’t do as well in terms of making their way from the deaf ear around the head to the hearing ear. This can cause a great deal of frustration for the individual with SSD especially when trying to communicate in the presence of background noise. 

By the way, are you asking if someone can be born this way?
