Age-related hearing loss (presbycusis) is common. Age-related hearing loss (presbycusis) is common. Aging and exposure to loud noises all contribute to hearing loss. Other factors, such as excessive earwax, can reduce the ability of the ear to carry noise over time. Most types of hearing loss cannot be reversed. However, you and your doctor or hearing care professional may take steps to improve your hearing. If you have sudden hearing loss, especially in one ear, seek medical attention immediately. Talk to your doctor if your hearing problems interfere with your daily life. Age-related hearing loss occurs gradually, so you may not notice it at first. To understand how hearing loss can occur, it may be helpful to first understand what you are hearing. Your ear is made up of three main areas: the outer ear, the middle ear, and the inner ear. Sound waves travel through the outer ear and cause the eardrum to vibrate. The eardrum and the three small bones of the middle ear increase the vibration when they reach the inner ear. There, the vibrations travel through the cochlea-shaped fluid in the inner ear (cochlea). Attached to the zero cells in the cochlea are thousands of tiny cheeks that help convert sound vibration into electrical signals sent to your mind. Your mind translates these signals into sound. Aging and exposure to loud noise can cause hair loss or zero cochlear cells that send sound signals to the brain. When these hair or nerve cells are damaged or lost, electrical signals are transmitted less efficiently, leading to hearing loss.
