How to know if you might be experiencing hearing loss?
The most prevalent symptom is that you believe you can listen but not understand certain conversations, resulting in you being an inactive listener. You may become irritated as a result of this symptom, and certain noises, such as the ringing of a telephone, may begin to aggravate you. You may develop severe symptoms such as tinnitus or a loss of balance as a result of this. Visit the nearest Audiologist In Chennai to consult and know about your condition.
Let us understand the different types of hearing loss along with their causes.
- Hearing loss caused by a malfunction in the inner ear or the auditory nerve is known as sensorineural hearing loss.
- Conductive hearing loss is caused by sound waves not reaching the inner ear as a result of a middle ear lesion or trauma.
- Mixed Hearing Loss is caused by a combination of the two forms of hearing loss outlined above.
Causes of Hearing Loss
Illness Related Hearing Loss
Hearing loss can be caused by a variety of illnesses and disorders, including the following:
- Eardrum Perforations – Hearing loss is caused by damage to the eardrum.
- Middle ear infections – The most frequent type of ear infection is an infection in the middle ear. It can cause hearing loss if left untreated or not treated in a timely manner. If you have an ear infection, you should always see an ENT doctor.
- Otosclerosis – This illness is caused by restricted motions of microscopic bones in the middle ear, which can lead to hearing loss.
- Meniere’s illness — Though the exact cause of this condition is unknown, the symptoms typically include dizziness, tinnitus, and vertigo-like symptoms.
Inherited Hearing Loss
This form of hearing loss is frequently genetic and can be conductive, sensorineural, or mixed in nature, as the name implies. Hearing loss is caused by a hereditary characteristic handed down from parents to their children. This sort of hearing loss is more common in children whose parents marry within the family [consanguineous marriage]. This type of hearing loss is usually present and detectable from the time a child is born, however it may progress gradually in rare situations. Treatment or a hearing aid is given depending on the severity of the hearing loss.
Noise Induced Hearing Loss
Noise-induced hearing loss can occur as a result of being exposed to loud noises, such as construction noises, traffic sounds, or loud surroundings, for an extended period of time. It can have a negative impact on your inner ear hair cells, resulting in partial or total hearing loss. Doctors and audiologists always advise using ear plugs or ear muffs in loud environments as a precaution, as well as making sure your earphones are utilised properly.
Hearing Loss caused by certain Drugs and Medicines
You might be startled to learn that certain medications and pharmaceuticals might cause hearing loss. Ototoxic medications are those that cause harm to the ears. The following are some examples of such drugs:
- Antibiotics with aminoglycosides
- Chemotherapeutic medicines
Of course, hearing loss does not occur after one or two doses, but hearing loss has been demonstrated to occur when dosages are eaten over a long period of time. Researchers are trying to figure out what’s causing this and what the safest dose is for these treatments, but no breakthrough has been made yet.
Head Trauma and Tumours
Hearing loss can also be caused by head trauma or some types of tumours. In the event of a head injury, the inner ear or another component of the ear may be destroyed, resulting in hearing loss.
Single Sided Deafness
Unilateral hearing loss, often known as single-sided deafness, can develop for any of the reasons listed above, or a combination of them.
