How do we manage to hear the sounds around us, and what might cause hearing loss? Here is your guide on hearing loss, causes, symptoms, diagnosis, and treatment.
Hearing impairment Although it often visits a person slowly, it is very common. While today it recognizes the age of aging, it threatens the younger generation for their way of life. So what is hearing impairment? How does the treatment happen and how can we avoid it? All this in an article
How is the process of hearing?
You hear when sound waves reach the internal organs or structures of the ear, in which the vibrations of sound waves are converted into nerve signals that are read and recognized by the brain as sound.
The ear consists of 3 main parts:
- The outer ear: that collects sound waves and directs them into the ear.
- Middle ear: This includes the eardrum that receives vibrations and amplifications of sound waves as they travel to the inner ear.
- Inner ear: Contains fluid in a snail-shaped canal with capillaries. These capillaries capture vibrations and convert them into electrical neural signals that travel to the brain to interpret them as sounds.
How does hearing loss happen?
Hearing impairment can result from the following:
- Inner ear damage: Noise and noise may tear the capillaries and nerve cells in the cochlea. When these cells are damaged, this will affect the delivery of electrical signals to the brain and thus hearing loss. It may become difficult for you to discern speech while there is background noise, and sometimes the genetic factor may play a role in reaching this result. This type of hearing loss is known as sensory nerve loss and is a non-refundable medical condition.
- Earwax buildup: Earwax buildup in it can lead to blocking access to its channel and thus preventing the conduction of sound waves, in this case it is sufficient to clean the earwax to restore hearing capacity.
- Ear inflammation or growth of tumors: These conditions may arise mostly in the middle and outer ears, and unfortunately they may lead to complete hearing loss.
- Tympanic rupture: or perforation of the tympanic membrane, a condition that may be caused by eruptions of loud noise or sudden changes in ear pressure which are conditions that affect the ability to hear.
Risk factors for hearing impairment
Here are the factors that, in turn, can lead to your hair and nerve cells in your inner ear:
- Aging: With age, degeneration of sensitive inner ear structures occurs, similar to corrosion of substances over time.
- High noise: may lead t offer high sounds to the inner ear cells damage may occur as a result of continuity in a slight exposure to noise or the result of a short burst of noise is very high.
- Genetics: You may be more likely to experience damage to the ear due to the genetic factor in the family.
- Occupational noise: If you are a worker who is exposed to regular loud noise from the work environment, such as blacksmithing, construction, or factory and machinery work, then you may be more likely than others to lose your hearing and damage the inner ear.
- Medicines: Some antibiotic and chemotherapy drugs can damage the inner ear. Very temporary effects, such as tinnitus or hearing loss, may occur if the doses are too high.
- Some diseases: Some diseases or those that lead to high temperatures may damage the cochlea.
Symptoms of hearing loss
Here are some symptoms that require you to pay attention to your hearing and determine if you need to consult a doctor:
- Mumbling of speech and other sounds
- Difficulty understanding words, especially in case of background noise
- Difficulty hearing the consonants
- Frequent requests from others to speak slowly and loudly
- The need to raise the sound of TV and appliances around you
- Withdraw from the talks
Hearing impairment complications
You may have noticed some of the symptoms that someone who suffers from hearing impairment will actually suffer from difficulty in communicating with his environment. Hence, hearing impairment may result in the following complications:
- False feeling that others are angry with you.
In general, those affected tend to hear denial of the matter before seeking treatment, which leads to some social difficulties with their relatives and companions. So be careful and reconcile with yourself, as treatment is the best solution.
Hearing impairment diagnosis
Here are some tests that you can expect at the specialist doctor:
- Physical examination: the doctor looks for a physical cause of the ear that may be the cause, such as earwax, inflammation, specific tumor, etc.
- General examination test: It is possible that the doctor will pass you a general hearing test during which he asks you to close an ear and try to listen to certain sounds and then switch between them.
- Tuning fork test: during which metallic instruments are used to check the ability to hear noise against low sounds: This examination helps to locate the defect in the ear.
- Hearing test: The patient wears headphones and listens to a group of sounds that hesitate with different powers and different frequencies, each time with a different ea
