The ear is divided into three basic parts – the outer, middle and inner ear. Each part serves a specific purpose in detecting and interpreting sound. Ear health encompasses numerous conditions that include earaches, tinnitus, vertigo, Meniere’s disease, ear infections and hearing loss.

Long-term exposure to high volume is the most common cause of hearing loss. Over time the tiny hair cells of the inner ear wear out and can no longer convert sound into nerve signals that go to the brain.

eHealth is the use of information and communication technologies (ICT) for health. eHealth can be used in treating patients, conducting research, educating the health workforce, tracking diseases and monitoring public health.
