If you experience these warning signs repeatedly or in combination, they may indicate a hearing loss. People seem to mumble more frequently. You experience ringing in your ears.

You no longer hear normal household sounds, such as the dripping of a faucet or the ringing of a doorbell.
Sudden hearing loss, the rapid loss of 30 decibels or more of hearing ability, can happen over several hours or up to 3 days. (A normal conversation is 60 decibels.) Sudden hearing loss usually affects only one ear. Although there are up to 3 new cases per every 10,000 people each year, doctors are not able to discover the cause in most cases. Illnesses such as heart disease, high blood pressure, and diabetes put ears at risk by interfering with the ears' blood supply.
