How hearing loss and deafness occur

Have you ever wondered how hearing loss and deafness occur? Let's delve into the causes of these conditions.

Hearing loss or deafness refers to a condition where hearing ability is reduced, which may be slight or

there might be no hearing at all (profound deafness). There are many main causes, such as ruptured eardrum, ear infection, congenital deafness,

Ménière's disease, age-related hearing loss, occupational hearing loss, etc.

1. Age-related hearing loss: Mostly, men are more likely to experience it than women. Symptoms usually appear when individuals are around

60 years old and above. The cause is due to age-related degeneration of the auditory nerve.

2. Occupational hearing loss: This often occurs in people who work in noisy environments exceeding 90 decibels for extended periods, causing

auditory nerve cells to be permanently damaged by sound waves. If one continues to work in the same environment, hearing loss will gradually

worsen until it leads to deafness.

How to know if you have hearing loss??? Would you believe that your work can easily be a primary cause of hearing loss?

People who work in noisy environments without protective equipment for long periods may initially experience temporary muffled hearing

and ringing in their ears. If no protection is used, hearing loss may eventually occur due to permanent damage to the auditory

nerve.

The main causes of occupational hearing loss from working in noisy environments are:

                                                                 - Sound intensity level: If working in an environment with noise exceeding 80 decibels, there is a risk of hearing loss.

                                                                   The louder the sound, the greater the risk of hearing loss.

                                                                 - Sound frequency: High-frequency or sharp sounds damage the auditory nerve more than low-frequency sounds.

                                                                 - Type of sound: Impact noise can damage the auditory nerve more than continuous noise.

                                                                 - Duration of work: People who work in noisy environments for many years have an increased chance of auditory nerve degeneration.

                                                                 - Use of noise protection equipment: Protection is only safe if the equipment is of sufficient quality for

                                                                   noise protection and the user can wear the equipment correctly.
