Hearing loss that gradually occurs with age (presbycusis) is common. About a third of 65 to 75 year olds in the United States have some degree of hearing loss. For those over 75, that number is roughly 1 to 2.
Hearing loss is defined as one of three types:
- Conductive (affects the outer or middle ear)
- Sensorineural (affects the inner ear)
- Mixed (combination of both)
- Aging and chronic exposure to loud noises both contribute to hearing loss. Other factors, such as excessive ear wax, can temporarily affect the quality of sound transmission through your ears.
The signs and symptoms of hearing loss can include:
- Choking on speech and other noises
- Difficulty understanding words, especially in background noise or in a crowd
- Difficulty hearing consonants
- Frequently ask others to speak more slowly, clearly, and louder
- The volume of the TV or radio must be increased
- Withdrawal from conversations
- Avoidance of certain social contexts
To understand how hearing loss occurs, it can be helpful to first understand how you hear.
- How do you hear
- In your ear

- Your ear is made up of three main areas: the outer ear, the middle ear, and the inner ear. Sound waves pass through the outer ear and cause vibrations in the eardrum. The eardrum and three small bones in the middle ear amplify the vibrations as they travel to the inner ear. There, vibrations occur in a spiral structure in the inner ear (cochlea) through the fluid.

Factors that can damage or lose hair and nerve cells in the inner ear include:
Aging. The degeneration of the structures of the inner ear occurs over time.
Loud noise. Exposure to loud noises can damage the cells in your inner ear. Damage can be from long-term exposure to loud noises or from a brief burst of noise, such as B. by a shot.
Inheritance. Your genetic make-up can make you more susceptible to hearing damage from noise or deterioration from aging. Hearing loss Treatment in Nizamabad
Professional sounds. Jobs where noise is an integral part of the work environment, such as farming, construction, or factory work, can damage the inside of your ear.
Leisure sounds. Exposure to explosive noises, such as Guns and jet engines, for example, can cause immediate and permanent hearing loss. Other leisure activities with dangerously high noise levels include snowmobiling, motorcycling, carpentry work or listening to loud music.
The following steps can help you prevent noise-related hearing loss and keep age-related hearing loss from getting worse:
Protect your ears. Limiting the duration and intensity of your noise exposure is the best protection. In the workplace, plastic earplugs or glycerin-filled earmuffs can help protect your ears from harmful noise.
Get your hearing tested. Consider regular hearing tests if you work in a noisy environment. If you have lost some of your hearing, there are steps you can take to prevent further loss.
Avoid recovery risks. Activities like snowmobiling, hunting, using power tools, or listening to rock concerts can damage your hearing over time. Wearing hearing protection or pausing noise can protect your ears. Turning down the volume of the music also helps. Hearing loss Treatment in Nizamabad
