Presbycusis is a gradual sensorineural hearing loss which starts exhibiting symptoms around the age of 50. This hearing loss is a result of the normal aging process but can be affected by outside causes, such as noise exposure.
A sensorineural hearing loss is a result of damage to the middle ear. This includes the hair cells inside the cochlea, as well as the auditory nerve which transmits signals to the brain. Presbycusis affects the ability to hear high frequency speech sounds which includes the “s”, “t”, “sh”, “f”, and “th” sounds. This affects conversation between the speaker and the listener, and the individual will have trouble comprehending what was said.
The Causes of Presbycusis:
Genetics: Presbycusis can be inherited just like other medical conditions.
Medication: Sometimes medicines can be the culprit of hearing loss. Consult with a doctor if there are changes in hearing.
Noise Induced: Has there been consistent exposure to loud noises, such as machinery or loud music?
Other medical conditions: Medical conditions such as high blood pressure can change the blood supply in your ears, triggering presbycusis.
Signs of Presbycusis:
- Unable to hear high frequency speech sounds
- Speech sounds unclear or muffled
- A few noises seem overly loud and annoying
- Ringing in the ears (tinnitus)
What steps to take if there is a possible hearing loss?
A doctor specializing in hearing, an audiologist, tests your hearing and will diagnose what type of hearing loss is occurring. The audiologist will explain a treatment plan; if indicated, he can fit a hearing aid according to need. Sometimes an audiologist will refer patients to an ENT physician to examine the inside of the ear. It is important to receive proper treatment for hearing loss. Uncorrected hearing loss can lead to a decrease in hearing. Inability to understand conversations can lead to feelings of isolation and depression.
