In children, this may result from illnesses such as measles, mumps or meningitis, but teenagers and adults are more susceptible to noise-induced hearing loss from loud music, sporting events and working environments. Head injuries, neurological disorders such as strokes and multiple sclerosis, and certain medications and chemicals can also cause hearing impairment, plus hearing deteriorates as part of the ageing process.
