Causes of noise-induced hearing loss | Symptoms & treatment

Ear damage due to noise

You are unlucky enough if your room is near a busy road. Beeps and horns can destroy your days and nights and you will become a permanent patient of depression and May lose a sense of hearing to some extent.

Nothing is more irritating than traffic noise it will responsible for ear damage as well as carcinogenic for a happy mood. No one can concentrate on their studies or job work because of these annoying circumstances.

What causes noise-induced hearing loss?

Shrieking noises can destruct the hair cells in the inner ear and the hearing nerve. This is called nerve deafness.

Hearing loss from loud noises will occur slowly and may take enough time means it’s a slow process but more damaging it may be eternal or short-term.

Common sources are listening to music, with the volume turned up too high.

Hiring Loss due to noise

No doubt bird’s chirping is soothing but Remember those days when the next day was your toughest paper and unfortunately, you slept and rely all the preparation on an upcoming morning and when suddenly you woke up and start memorizing things and you listen to a rooster’s crow and lost all of your concentration alas! It was a big loss man heh-heh. This is how noise can also destroy your career.

Noise generates a lot of health issues including mental stress, indigent attentiveness, less productivity in the workplace, and communication problems, and tiredness because of insufficient sleep.

It causes more severe cases such as Heart diseases, perceptive disability, booming sensations in one or both ears, and hearing loss.

 Sound has an essential role in daily life. But when sound becomes clangor, it harms our mental health and sense of hearing. Nowadays noise becomes a routine part of the modern world.

it is becoming the worst reality of urban life and we should take it seriously and should find various ways to minimize its harmful effects.

Tinnitus is referred to as ear infection and beating in one or both ears in the absence of external sound stimulus which is because of constant noise it may cause insomnia, tension, aggression, inability to work.

Noise is a common trigger that causes adverse health effects comprising a higher risk of cardiovascular diseases e.g. high blood pressure, heart failure, and irregular heartbeat. Cardiovascular disease includes ischemic disease which includes angina

There is a strong relationship between traffic noise and cardiovascular problems in children. Both traffic noise and aircraft noise increases blood pressure.

Noise is an undesirable sound, and its effect on health is mostly ignored people adapted this condition, levels of adaptation differ for every person. If noise pollution increases from a definite level then consequences will be horrible. Mostly in textile mills where noise is unbearable people suffering from hearing loss.

Aircraft noise also affects the auditory sense of a staff member of the airport. Noise is everywhere in urban areas and the availability of calm spots is rare. There is a slight difference between industrial and environmental noise.

Noise is the main cause of hearing loss. Acute reckless sounds like gunfire and any other sharp shrieking sounds cause noise-prompted hearing loss. Noise-induced hearing loss is the damages of auditory sensory cells in the cochlea.

Because these hair cells cannot revive in vertebrates, deterrence of noise-induced hearing loss is the only way to prevent hearing loss. Hear loss is directly proportional to the inability to be aware of everyday conversations. And decrease the ability to complete any tasks.

Noise-persuaded heart loss is a common health problem. The research estimated that 1·3 billion people are affected by hearing loss and. Hear loss is the 13th most important agent in the disabled portion of the world.

In the USA and Europe, 26% of adults have both ears hearing disorders that damage their capacity to hear in noisy situations, and 2% have single ear hearing issues.

WHO estimates that 10% of the world community is bare to sound pressure degrees that could cause noise-induced hearing loss. In half of these people, ear damage may because of disclosure to intense noise.

Despite enough efforts in developed countries against noise pollution this issue is still unsolved and remains budged. Noise-induced hearing is the most common disease in the USA: about 22 million US workers are exposed to hazardous noise levels at work.

Many countries imposed health and safety laws that are deliberate to protect both workers and the public from immoderate noise pollution.

The actual degree of noise exposure in industrial premises that bring the risk of auditory loss is a hot topic internationally.

Noise-induced hearing loss and Age Limitation

The population of all ages can be ostentatious. Evoked to different types of noise from early childhood have effects on hearing damage in adulthood.

Scientific improvements and Medicinal procedures

Recent therapists are using stem cells to recover the damaged sensory circuitry in the cochlea at a very premature age.

Prediction                                                                              

Several therapeutic methods are recently discovered, and oral drugs to prevent noise-induced hearing loss are awaited to become available in the next 10 years

Studies also showed that antioxidant compounds, such as glutathione, have upgrade noise-induced hearing loss in animals and might protect against noise-induced hearing loss

Cardiovascular disease

Long-term exposure to surrounded noise affects the cardiovascular system. It also affects the autonomic nervous system and endocrine system noise exposure increases systolic and diastolic blood pressure, changes pulse rate, releases stress hormones (including catecholamines and glucocorticoids).

Potential mechanisms are emotional stress reactions due to consciousness tenderness (indirect pathway), and physiological stress from interactions between the central auditory system and other regions of the CNS (direct pathway). The direct pathway might be the main mechanism in sleeping persons, even at low noise levels.

Environmental noise exposure harms children’s learning capabilities and that children with jet, airships, road traffic, or rail noise exposure at school have bad reading ability, memory, and performance than children who are not exposed to noise at school.

Extrinsic noise effects on hospital territory are very infrequent. But indoor hospital noise effects on patients and staff have been enhancing.

Many sources cause noises in hospitals like telephone rings, alarms for medical staff, and nursing activities such noises may cause disturbance for patients mainly in elder patients, and increases their cardiovascular stress decreases the effects of pain relief drugs mostly people complain about sleep disturbance.

Verification of bad effects of noise on hospital staff is expanding day by day, specifically for nurses, with noise-induced stress linked to mental exhaustion, decreases work performance, affects speech ability which may lead to misinterpreting which in turn causes medical flaws.

Such ceilings should be constructed which can absorb noise it will bring a good impact on staff performance and minimize their work stress. Reduced volumes are preferred to avoid unwanted noise.

Symptoms of noise-induced hearing loss

  • Difficulty in listening dim or low pitch sounds
  • Clicking sounds in the ear without any external source

Diagnosis

An ENT physician is a specialist who handles the problems of ears, nose, and throat.

Treatment

Once the hearing nerve is damaged, it is gone because no regeneration process occurs in mammals. But as discussed earlier that physicians can use stem cells for recovery of the damaged cochlea.

Prescriptions

 To protect from further hearing loss, keep the persons away from loud noise. But if it is not possible to avoid loud noises one can use earpieces,
