SonoVive Hearing loss may be partial or complete. Such an instance is whereby a person may not be in a position to detect sound at various frequencies. In order to aid such a person in hearing, a Clear Hearing is used. Its use is to amplify sound such that the person using it will be able to hear sounds that he or she may not hear when not wearing it. These devices usually amplify sound to a frequency level that the person will hear and a healthy level. This is because too much noise would worsen the situation.
