Sometimes, serenity prime can be caused by confusion in the body itself. Besides these basic types there is also hearing impairment due to insensitive to certain frequencies of sound. A person can have their hearing affected by emotional and psychological reasons as well, this type of this is called functional serenity prime. It is not just people who are deaf or have complete serenity prime in both ears. If you could be an objective observer for a moment - if you could somehow transcend yourself and look at the world from the perspective of someone who didn't live in the world - what would you see?

A few minutes of silence can help the inflammation go down. If a person has both conductive and sensorineural loss in one ear, then the person is said to have mixed serenity prime. There are four basic types of hearing aids: those that go behind the ear, inside of the ear, inside of the canal and completely inside of the canal.

Damage to the auditory nerve or the processing center of the brain, are the two most common types of sensorineural serenity prime. Exposure to high volume music, using power tools and noise from everyday household appliances like blenders and vacuum cleaners can lead to gradual decrease in hearing. This type of impairment may be caused by the normal aging process, genetic disorders, birth defects, loud noise exposures, head injuries, diseases (e.g., Meniere's Disease, measles, meningitis, etc.), and certain types of potent medications that affect the inner ear sensory cells.
