This damage could be present in newborns or it could be brought on most often from loud noise. Sounds in the low frequency register (under 2 kHz), are sounds such as thunder, a tuba, a large dog's bark, or a truck rumbling by on the highway. Ordinarily people start to notice more and more of their sonovive after they start to hear less and less. This type of sonovive is difficult to diagnose even with in-center testing options. For persons with hearing difficulty that is mixed in nature, there is damage in the outer and/or middle ear, as well as the inner ear and/or hearing nerve.

For high frequency sonovive, this is usually a very effective solution. If you notice that your child is not responding to noises as they normally would, and if they are in the middle of being treated for an ear infection, one of two things are going on. There is no way to reverse age or noise induced sonovive.
