Common Hearing Impairments
Tinnitus
Perception of ringing or buzzing in the ears when no external sound is present.
Noise-Induced Hearing Loss
Hearing loss caused by exposure to loud noises over time or sudden extremely loud noises.
Age-Related Hearing Loss
Gradual hearing loss that occurs as people get older, usually affecting both ears equally.
How Hearing Impairment Affects Sound Perception
- Damaged hair cells in the cochlea can't effectively convert sound vibrations to electrical signals.
- This can result in certain frequencies being harder to hear or completely inaudible.
- Tinnitus can cause persistent ringing or buzzing, interfering with normal hearing.
- Exposure to loud noises can cause temporary or permanent damage to the auditory system.
Did You Know?
The human ear can detect sounds ranging from 20 Hz to 20,000 Hz. However, this range typically narrows with age, a condition known as presbycusis.
