Hearing is a sense that we are born with and without which we cannot live a comfortable life. Hearing may suddenly decrease over time. When it decreases progressively, we do not realize it from the beginning. It has been found that there is a period of at least 7 years from the onset of hearing loss until the patient presents to the audiologist clinic to find out the cause of the hearing loss.
How can we know in advance if our hearing loss?
If you answer YES to the following questions, you may experience hearing problems:
Turn up the volume on the TV or radio frequently
You have difficulty understanding a telephone conversation
He often asked people to repeat what they said
You don’t understand what’s going on around you
Don’t understand group conversations
You pretend to understand what is being said in noisy places
You feel embarrassed to open a discussion about hearing loss
As we mentioned earlier this hearing loss occurs over time, we initially realize this aspect; we will blame those around us for talking too slowly or for too much noise in the room. The first to notice that our hearing has been impaired are family and friends. They will notice that we make them repeat what they said or they will notice a nervousness on our part and a withdrawal from the conversations.
There are three types of hearing loss:
Neurosensory hearing loss: decreased ability of the auditory nerve and inner ear to function
Transmission hearing loss: when there is a problem with the external auditory canal, the middle ear
Mixed hearing loss: when there is a combination of the two.
