Shingles is caused by the varicella-zoster virus â the same virus that causes chickenpox. Anyone who's had chickenpox may develop shingles. After you recover from chickenpox, the virus can enter your nervous system and lie dormant for years.
Hearing loss, also known as hearing impairment, is a partial or total inability to hear. A deaf person has little to no hearing. Hearing loss may occur in one or both ears. In children hearing problems can affect the ability to learn spoken language and in adults it can cause work related difficulties.
Nine out of ten people with SSHL lose hearing in only one ear. SSHL is diagnosed by conducting a hearing test. If the test shows a loss of at least 30 decibels (decibels are a measure of sound) in three connected frequencies (frequency is a measure of pitchâhigh to low), the hearing loss is diagnosed as SSHL. As an example, a hearing loss of 30 decibels would make conversational speech sound more like a whisper.
