Symptoms could range from a short period of time with thin and clear, noninfected fluid. They are especially suitable for young children for growth and safety reasons. In this situation, loved ones also escape from the trauma of making a hearing deficient patient understand. Damage to the middle ear and punctures to the ear drum can cause loss, as can skull fractures and other traumatic injuries to the brain.

Central hearing loss is also not a standard hearing loss, but it is due to dysfunction in the central processing areas. It's thought the increasing sound that's a natural, unavoidable part of the world we live in... workplace sound, traffic noise, jackhammers, sirens and such, are the reason so many more of us are losing our hearing, especially those at lower social and educational levels. Persons with this type of loss may complain that sound is soft, muffled, and distorted. The constant ringing, buzzing, swooshing or other unique noises with no outside cause or source is what is referred to as sonus complete and more commonly called "ringing in the ear".
