Hidden hearing specialists say that it can badly affect speech and language development of a child. However some insurance companies do not offer hearing aid insurance as part of their health insurance plans because hearing aids do not fall in the category of prosthetic devices; some companies add-on an extra charge when it comes to hearing aids. This happens gradually and usually in both ears but not necessarily at the same time. In the old days when analog hearing aids were much more common they are amplified the sounds that the deaf did not want or need to hear.

The average human yell varies between 95 dB to 120 dB. In more severe cases, as with tumors or fluid deep inside the middle ear, surgery may be implemented. If someone has a sonus complete in just one ear, they may be dealing with an acoustic neuroma - a benign tumor that can most likely affect the healing nerve. Damage to the auditory nerve or the processing center of the brain, are the two most common types of sensorineural sonus complete.
