While most noise is just in the background for us, loud noises, either in small spurts or prolonged exposure, can cause hearing loss. This has been happening more frequently as the levels of noise in an industrialized society go further up.

Noise induced hearing loss explained
Loud noises may damage the sensitive structure of your ear, which process the sound waves into information. They eventually become nonfunctional, resulting in a loss of hearing in that range. If exposure to loud noises continues, then this might extend to the entire range of hearing and may cause total hearing loss.

What may cause noise induced hearing loss?
Some of the scenarios which may cause noise induced hearing loss are as follows:
1. Listening to music on high volume: If you constantly listen to music or watch movies at your home on very loud levels, then it may result in noise induced hearing loss. In fact, listening to music or watching movies with headphones in your ears is one of the leading causes for hearing loss. Headphones have deceptively loud levels and may result in damaged hearing overtime.

2. Noise of household tools: Household tools such as drills, mixers, grinders, mowers, and saws can expose you to loud levels of noise. Even a quick exposure for a few seconds could temporarily damage your hearing. 

3. Occupational problems: Occupations such as construction, factory work and military that require the use of power tools on a constant basis can also cause hearing loss. The sound from the resulting friction might damage your hearing very quickly. Explosions and impacts are also causes of hearing loss in the military and law enforcement departments.

Prevention and treatment
Treatment: It is difficult to treat hearing loss as in most cases; it may be permanent, except sudden shocks, when your hearing might come back to normal. The only treatments for hearing loss are hearing aids or cochlear implants which can restore hearing partially.

Prevention: Prevention is the best method to avoid hearing loss and in most cases, you should wear ear protection such as mufflers or sound level reduction devices to protect your hearing. Also, practice listening to music, watching TV or movies at lower levels, especially if you are on the headphones. 

Induced Hearing Loss - Facts You Should Be Careful about It!

Hearing loss is experienced by millions of people these days. Ageing is not the only factor that brings hearing impairment. The causes are many. Certain medications, continuous exposure to loud noise, genetic involvement, injury and some medical conditions may cause hearing loss.

There are quite a few myths that people have come to believe about hearing loss over the years. Since it is such a common phenomenon, here we take a look at the common myths surrounding hearing loss.

Myth no. 1: Hearing loss is exclusive to elderly.

Fact: As said before, hearing loss can be an outcome of various causes. Nearly half of the people suffering from the same are below the age of 55 years. No matter what your age is, you must always get your ears checked, especially if you are feeling that are you missing things.

Myth no. 2: Diagnosing hearing loss is easy.

Fact: Most people do not come to know about the condition until it gets worse. Also, your physician never really checks for hearing loss symptoms in a general check-up unless you ask for it specifically.

So, always get a check-up done, like you do for other probable diseases.

Myth no. 3: There's no effective solution for hearing loss.

Fact: Like there have been advancements in the medical field for everything else, there are aids available these days that improve your hearing and have finer adjustments for noise adaptation. Also, there are certain other procedures and surgeries that have proved to improve the condition in many.

So, seek help as soon as possible.

Myth no. 4: The sounds aren't loud enough; my ears are healthy and fine.

Fact: If there is a problem you're experiencing with hearing, you have got to accept that and get it treated. Avoiding a certain condition will only get things worse for you.

Also, hearing aids are no more a stigma. Ear aid devices have designs similar to earphones these days, which are comfortable enough to wear. Ignoring a medical condition or inability to accept the same would only do more harm instead of making things fine.


Common Myths About Hearing Loss

BAHA Implant
Bone Anchored Hearing Aid (BAHA) is a device surgically implanted to help people suffering from a loss of hearing. Most conventional hearing aids transmit sound through air conduction. The BAHA device is suitable for conductive or mild-moderate mixed hearing loss.

Problems with hearing in the middle or outer ears can be helped with the BAHA device. The sound waves received by the BAHA device bypass the middle ear and get delivered straight to the functioning cochlea in both ears.

A BAHA device comprises of two parts:
a) The processor 
b) A fixture which is surgically implanted behind the ear in the bone.

The implant is embedded in the bone. The processor, which remains outside, is attached to the implant. There is a microphone on the processor that picks up sounds. The sounds are passed on to the implant. The implant vibrates which triggers the Cochlear. You can consider wearing a BAHA implant if other conventional hearing aids do not work for you. BAHA implants are also given to people with collapsed or irritated ear canals.

Cochlear Implant Surgery

A complex, small electronic device that helps hearing in people with severe hearing loss or deafness is used in the Cochlear Implant Surgery. The cochlear implant comprises of an external piece behind the ear and another piece that is surgically implanted under the skin. A cochlear implant comprises of four parts:
1. A microphone which picks up sounds from the surroundings
2. A speech processor which chooses and arranges the sounds the microphone picks up
3. A receiver/stimulator and transmitter that picks up signals from the speech processor and changes them into electric impulses
4. An electrode ray, a bunch of electrodes, receives impulses the stimulator sends and transmits them to different areas of the auditory nerves.
The implant does not cure deafness; it only gives you a useful portrayal of sounds in the environment and considerable aid in understanding speech.

The surgery is done in the following way:
i. The area around the site of the implant is shaved or cleaned
ii. The patient's vital signs are monitored through cables, patches and monitors attached to him or her
iii. General anaesthesia is administered through IV or through a face mask
iv. After the device is implanted, the patient is taken to the recovery room for the anaesthesia effect to lessen.

BAHA Implant and Cochlear Implant Surgery

It is that time of the year when insects are all around. Suddenly one feels a buzzing sound or an itchy feel in the ear. To your horror, one feels a live insect is in your ear, which can be extremely annoying and is like a nightmare. Insects often get stuck when they enter our ears as they cannot fly or crawl out. They try to find their way out and their movements inside our ears can be very uncomfortable, painful and can be itchy as well. Moreover, they can easily produce infection.

In this scenario, do not try to remove an insect with cotton swab, tweezers or hair clip as it will make the situation worse and can lodge the insect deeper into the ear canal, which can possibly damag the eardrum, leading to permanent hearing loss. If an individual is not certain about the potential harm taht can be caused by the insect in the ear, one should seek medical care immediately. Insects in the ear are common reasons for visits to doctor's clinic, especially in children.

If one suspects an insect in ear, one may experience pain, swelling, blood or crackling. One may even feel biting, stinging, hearing loss or dizziness. It is best to stay calm in this situation as being active may lodge the bug further in ear or cause it to move further back or cause serious damage to the sensitive eardrum

One way to try to remove a bug in ear is by tilting the ear toward the ground and attempt to wiggle the ear. Grasp the earlobe and give it a wiggle. If the bug is not too far into ear canal, it may fall out on its own. If the bug is still alive and is not too far inside of the ear canal, it may simply come out on its own. If one stays calm and keep objects including fingers away from ears, it is likely that the bug will find its way back out of ear.

One can also try to flush the ear with warm water with a dropper or a bulb syringe. This can be done by holding head upright and stretching the ear canal by pulling the outer ear and then putting a steady stream of warm water into ear. Tilt head to the side to drain out the ear. Do not try this if one suspects that ear drum has been ruptured to prevent additional damage.

To avoid stinging or eardrum rupture from scratching or biting , one may use a drop or two of mineral, baby, or olive oil inside your ear canal to kill the insect. Finally, visit an ENT specialist doctor as they can remove the insect by special suction devices. Post insect removal, one must look out for signs of infection as swelling, dizziness, hearing loss, fever, and pain. Finally follow up with ENT specialist or Otolaryngologist for the final opinion.

How to Remove Insect from Ear at Home? 

Cochlear Implant is an electronic device replaced with the inner ear (cochlea) of the patients who are unable to send sound waves to the brain.

The surgery is performed on the patients who have the problem of hearing loss due to the damaged hair cells in the inner ears. The implant helps the patient to hear which are not responding to other hearing aids.

Conditions for Cochlear Implant:

Cochlear implants help people to hear with clarity. They are not like hearing aids, which make the sound louder, but it helps send sound waves to the brain and replaces the damaged hair cells in the inner ear. Following are cases where it is beneficial:

People who find it difficult to hear clearly with hearing aids.

Those with moderate hearing loss in both ears.

Patients with 50% or fewer score in the sentence recognition test.

Patients with 60% or less score in sentence recognition test with hearing aids on.

It is suggested to opt for cochlear implants in both ears. The reason is to give the patient a better perspective of sound direction and clarity in understanding the words.

How does the Cochlear Implant work?

Cochlear Implant is an electronic device with an embedded sound processor that has to be worn outside ears or on the body. Following steps are involved in cochlear implant:

The sound captured by the processor is converted digitally by the processor and sent to the coil inside the ears of the patient.

The implant converts digitally coded sound waves to electrical impulses.

The electric impulse simulates the hearing nerve of the patient.

Then sends these impulses to the brain.

Benefits of Cochlear Implants:

The cochlear implant is a blessing for people who have been suffering from hearing loss for a very long time. It provides aid to people who have not benefited from hearing devices. The benefits of the cochlear implant are:

Hear better.

Studies have shown that people with cochlear implants have better sentence recognition scores instead of hearing aids.

The patient can concentrate better in the crowd and can hear conversations across the table.

Reconnect with the missed sounds.

Enjoy music on the phone.

Cochlear Implant improves the quality of life of people with hearing loss. It gives them an aid to understand and engage themselves in a conversation. However, it takes time to learn the interpretation of the sound signals that are received from cochlear implants. But, the patient can learn and lead a normal life with the implant. The factors which affect the benefits of Cochlear implants are:

The extent of hearing loss

The duration of the hearing loss and the condition before implantation

Damage to inner hair cells

Other health issues

The practice and rehabilitation time have been done in practice after implantation

The cochlear implant is performed in the patients after taking extensive tests determining the condition of the patients. It is activated after 2-6 weeks of surgery to give the surgery site a time to heal. Most people are discharged from the hospital after surgery and are prepared for the use of an implant. There are training sessions and classes for patients who have just gone for cochlear implants.

Cochlear Implant - How Do They Help?

What causes hearing loss? + How to ensure you can help it as you age

The partial or total inability to hear is known as hearing impairment or hearing loss. It can be present at birth, or develop later in life.

There are a number of factors, which may cause hearing loss

1. Age - Age is the biggest factor when it comes to the loss of hearing, and you may lose the ability to hear as you age. This condition is known as presbycusis. It becomes difficult to understand high-frequency sounds like that of a child or a woman when you get old.

2. Noise - When you are exposed to loud noises for a prolonged period of time, it damages your ears. This leads to loss of hearing. 5% of the total population of the world is affected by noise (the degree of suffering varies). It may be a result of continuous exposure to loud music or a sudden exposure to a loud noise like an explosion.

3. Hereditary disorders - Hearing disorder may be inherited by the dominant or recessive genes of parents in the child. 70-80% of these cases inherit from the recessive genes, whereas 20-25% inherit hearing loss from the dominant genes.

4. Trauma - Serious injuries of the head/ears may cause loss of hearing, which may be either temporary or permanent. When damage is caused to the brain, the brain fails to process the message conveyed by the ears. So even if the ears are totally functional, a person may face the problem in hearing.

5. Perinatal problems - The ototoxic effects on the fetus due to excess intake of alcohol during pregnancy lead to hearing the loss in about 64% of the infants born to alcoholic mothers.

Also, premature birth can be associated with hearing loss due to high risk of being exposed to noise in neonatal units.

Knowing about the causes of hearing loss can lead you a step closer to preventing this disorder as you age.

Here are some useful tips that can help prevent hearing loss:

1. Be more aware - You should be diligent and aware of the situations, which may risk your hearing ability and should try to avoid such situations as much as possible. Limit your exposure to sources of hazardous noises like firearms, firecrackers, concerts and clubs.

2. Take precautionary measures - If your occupation calls for working at an environment of loud noises, use earplugs or earmuffs to block out the excessive noise. Also, make sure that you work in a place where employers take all the necessary measures of noise control under the federal or state regulations.

3. Monitor your use of gadgets - Monitor and control the use of hearing devices, and try to reduce the use of headphones/ earphones as much as possible.
