Hearing impairment is common as people age, affecting a significant portion of the population. In our country, about one-third of individuals aged 65 to 75 experience some form of hearing difficulties. For those over 75, nearly half are affected.
Types of Hearing Loss
Sensorineural: Damage to inner ear structures
Conductive: Issues within middle or outer ear
Mixed: Combination of both types
Usually, prolonged loud noise exposure or aging causes hearing issues.Earwax buildup can temporarily impair hearing but is reversible. While permanent hearing loss cannot be cured, steps can mitigate its effects.
Signs of Hearing Loss
Difficulty understanding speech, especially in noisy environments
Frequently asking others to repeat themselves
Withdrawing from conversations
Sounds are muffled
Can't hear consonant sounds clearly
Raising volume on TV or radio
Common Causes
Earwax Accumulation
Build-up can block sound transmission through the ear canal, leading to temporary hearing issues.
Infections or Growths
Tumors, infections, or abnormal growths can impair hearing.
Inner Ear Damage
Exposure to loud noises or aging damages nerve cells in the cochlea, disrupting sound signals.
Eardrum Rupture
Sudden loud noises, injuries, infections, or pressure changes can cause eardrum perforation, resulting in hearing loss.
Risk Factors
Age
Hearing decline is common with advancing years.
Health Conditions
Diseases like meningitis or high fever can harm inner ear structures.
Medications
Some drugs, including certain antibiotics and chemotherapy agents, might damage ear cells or cause temporary tinnitus.
Genetics
Your genetic makeup can influence vulnerability to age-related hearing loss.
Noise Exposure
Prolonged or sudden loud sounds, such as gunshots or explosions, can cause lasting damage.
Recreational and Occupational Noise
Activities like listening to loud music, riding motorcycles, or working in factories can harm hearing over time.
