What is hearing loss?

After our eyes, the most important sensory organ is our ears, thus hearing impairment has significant consequences. In most cases, hearing loss is age-related. However, it can also be triggered by loud noises or infections, or may be hereditary. Hearing loss may occur very suddenly, although in most cases it is gradual, and so you only become aware of it as it progresses. Fortunately, in most cases impaired hearing can be improved, or even fully corrected, using a hearing aid. Find out how.
