Hearing loss is a common sensory problem that generally develops with increasing age or due to prolonged or persistent exposure to loud noises. It is one of the most typical problems that occurs throughout the world. If you are suffering from partial hearing loss, you may find ways of keeping in touch with your family and friends. If you are not suffering from such the following may help you keep your hearing intact for years to come.

Types of hearing loss
There are two main types of hearing loss: 
1. Conductive hearing loss where the problem lies in the middle ear, eardrum or ossicles. A conductive hearing loss affects the passage of sound between the eardrum and the inner ear. Sound passes down the ear canal to the ear drum and through the middle ear, where the sound is transmitted across the middle ear by the three bones called the ossicles to the inner ear.

Causes of conductive hearing loss:
1. Malformation of outer ear, ear canal, or middle ear structures
2. Fluid in the middle ear from colds
3. Ear infection (otitis media - an infection of the middle ear in which an accumulation of fluid may interfere with the movement of the eardrum and ossicles
4. Allergies
5. Poor eustachian tube function
6. Perforated eardrum
7. Benign tumors
8. Impacted earwax
9. Infection in the ear canal
10. Foreign body in the ear
11. Otosclerosis

2. Sensorineural hearing loss where there is damage in the inner ear, cochlea or hearing nerve. Sensorineural hearing loss (snhl) occurs when there is damage to the inner ear (cochlea), or to the nerve pathways from the inner ear to the brain. Most of the time, snhl cannot be medically or surgically corrected. This is the most common type of permanent hearing loss.

Causes of sensorineural hearing loss:
1. Exposure to loud noise
2. Head trauma
3. Virus or disease
4. Autoimmune inner ear disease
5. Hearing loss that runs in the family
6. Aging (presbycusis)
7. Malformation of the inner ear
8. Meniere's disease
9. Otosclerosis 
10. Tumors

Coping with hearing loss
Antibiotics and eardrops are often prescribed to treat hearing loss and its symptoms. In many cases, people suffering from severe hearing loss use hearing aids. Hearing aids are tiny instruments that people use in their ears to make sounds louder. People who suffer from hearing loss cope with their problems through increased concentration and focus. The usual way involves reading the moving lips of the person while they talk. Prevention is better than cure and is the best solution to avoid long term hearing loss. Avoiding continuous loud noises, to the possible extent helps prevent hearing loss to a great extent.

All About Hearing Loss

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.



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

Your hearing is one of the most important function your body carries out and sometimes you realize that you are losing your sense of hearing, when it is too late to get it back. There are two main reasons for this. One of the reason is age  and the other is when the inner ear's hair cells break down and do not pick up sound well. Here are 7 ways to safeguard your hearing.

1. Try to avoid loud places
It is not advisable to go to places where you have to shout to be heard, such as in a street, a concert or a construction site.

2. Buy low noise rating equipment
The equipments in your house will make sound that you hear the most. Try to avoid these equipments by buying appliances with a low noise rating.

3. Wear hearing protection at loud places
However, it is true that it is not always possible to avoid loud noises. This is when you need to get hearing protection. Earplugs and earmuffs are two of the best ways to make sure that even when you are in a loud place, your hearing does not get affected. Earplugs and earmuffs generally reduce sound by 15 to 30 decibels, which may be crucial to make sure that later in your life, you do not lose your hearing.

4. Avoid smoke
Smoking raises your chance of hearing loss. Second hand smoke does the same thing. Therefore, try to avoid, both smoking and secondhand smoking. 

5. Remove earwax properly
Earwax cannot be removed properly using a cotton swab. Instead, you should use an irrigation kit. Remember this as otherwise; the earwax could muffle your hearing.

6. Avoid medications which reduce hearing
Certain medications increase hearing loss. Therefore, double check with your doctor to make sure your medicines will not make you lose your hearing.

7. Get your hearing tested
Finally, get your hearing tested as identifying the problem early on can help stop worsen the situation.

7 Tips to Safeguard Your Hearing

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?

Did you know your earphones are making you deaf? Here's how.

Fact: Roughly 1.1 billion people worldwide within the age group of 12-35 have been found to be at an increased risk of developing hearing problems.

Listening to loud music on handheld devices using earphones has become a common trend among youngsters these days. You might find it very relaxing to plug in your earphones and escape into your own world of music, but you need to know that this can cause serious damage to your ears. The worst part: you won't realise your ears are being damaged until it's too late.

So, exactly how is loud music damaging your ears?

Continuous exposure to loud music from earphones or other sources results in a medical condition known as Noise-Induced Hearing Loss (NIHL), which can be associated with irreversible damage to the ears resulting in deafness.

When you hear loud music for a considerable amount of time every day it affects your hair cells (nerve cells responsible for sending sound signals to the brain) negatively, so that their ability to respond to sound decreases. If this keeps on happening for many months, eventually the hair cells are damaged beyond repair. These cells cannot be regenerated, making you permanently deaf.

How loud is too loud?

If your ears are exposed to sounds at 95, 100, 105, 110 and 115 dB (decibel, the unit used for measuring sound) for 4 hours, 2 hours, 1 hour, 30 minutes and 15 minutes each day respectively, your ears are at risk of getting severely damaged. Also, playing music at 120 dB or above can damage your ears instantly. You can have a realistic idea about the relation between decibels and sounds you commonly hear by referring to this list:

30 dB: soft whisper
75 dB: busy traffic
90 dB: noise of a motorcycle at 25 feet
100 dB: noise of a farm tractor
140 dB: jet plane taking off
Moreover, if you experience the following symptoms regularly, there's a high chance that you need to get your ears treated soon:

A ringing sound in your ears when you are at a quiet place, which vanishes after a few minutes
You need to raise the volume of TV or music to the fullest to hear it properly
You have difficulty in hearing people talking at a distance of just 3 feet
Tips For Safer Listening

Use earplugs: The louder the noise and the longer you're exposed to it, the greater the chance of damaging your hearing. Protect your ears with ear protectors   earplugs or earmuffs   and get away from the noise as quickly or as often as you can. 
Turn down the music: Don't listen to your personal music player at very high volumes and never to drown out background noise. If the music is uncomfortable for you to listen to, or you can t hear external sounds when you ve got your headphones on, then it's too loud. It's also too loud if the person next to you can hear the music from your headphones.
Use the 60:60 rule: To enjoy music from your MP3 player safely, listen to your music at 60% of the maximum volume for no more than 60 minutes a day. 
Wear headphones: When listening to your personal music player, choose noise-cancelling headphones, or go retro with older muff-type headphones. Ear-bud style headphones and in-the-ear headphones are less effective at drowning out background noise. 
Turn down the dial: Turn down the volume on your TV, radio or hi-fi a notch. Even a small reduction in volume can make a big difference to the risk of damage to your hearing. 
Use earplugs when you re listening to live music: They can reduce average sound levels by between 15 and 35 decibels. They re widely available at many live music venues and shouldn t spoil your enjoyment of the music.
Don't put up with work noise: If you re experiencing noise at work, talk to your human resources (HR) department or your manager and ask for advice on reducing the noise and getting hearing protection.
Wear ear protectors: Wear ear protectors (earplugs or earmuffs) if you are using noisy equipment such as power drills, saws, sanders or lawn mowers.
Be careful in the car: Listening to music in a confined space increases the risk of hearing damage. Don t listen to music too loud for too long.
Have a hearing detox: Give your ears time to recover after they ve been exposed to loud noise. According to Action on Hearing Loss, you need at least 16 hours of rest for your ears to recover after spending around two hours in 100dB sound, for example in a club. Reducing this recovery time increases the risk of permanent deafness.

Your Headphones Can Turn You Deaf!! 

The sense of hearing is a complex one. The ears are divided into three parts: the outer ear, the middle ear and the inner ear. While the outer ear sends the sound to the middle of the ear, the middle ear sends the same to the inner ear through the conductor. The inner ear in turn sends the auditory signal to the brain where the signal is processed and gives rise to a sense of hearing. 

Problems in hearings can arise if there is a problem in any of these parts. However, more often than not it is the middle or inner ear that is affected. However, there may also be situations when there are problems in both the middle and the inner ear. In that case, it is known as a mixed hearing loss. 

What is Mixed Hearing? 

Loss If there is damage to the middle ear, it may precipitate a conductive hearing loss. Now, in addition to that, if there is a sensorineural problem, then it gives rise to mixed hearing. So, in the case of a mixed hearing loss, all the parts of the ear and even the brain may be involved. There may be damage to the outer ear, middle ear, inner ear, as well as the auditory nerve. 

Causes of Hearing Loss 

Since mixed hearing loss may result from damage to any part of the ear, it is necessary that the causes be grouped into different categories. 

  Sensorineural Hearing Loss 

Sensorineural loss may result from drugs, different illnesses, head trauma, malformation of the inner ear etc. Genetic predisposition may also precipitate such problems. 

  Conductive Hearing Loss 

Such type of hearing loss may result from excessive deposition of earwax, ear infections, perforation in eardrums, malformation of the middle or outer ear, as well as problems with the fluid in the middle ear. 

Symptoms of Hearing Loss 

Reduced hearing in either or both ears is considered to be delineating symptoms of mixed hearing loss. 

Treatment 

Since mixed hearing loss can result from sensorineural failure as well as damage to outer or middle ear, treatment needs to be divided into different groups too.   To treat Conductive Hearing Loss, doctors can use surgical or medical options. 

  For sensorineural hearing loss, doctors usually prescribe hearing aids. This indicates that treatment for mixed hearing loss may include treatment for conductive hearing loss as well as that for sensorineural hearing loss. So, it is usually a combination of both medical and surgical options. Physicians may prescribe both medicines and hearing aids or resort to surgical interventions and also prescribe hearing aids. Sometimes, physicians use special hearing aids or implants to treat mixed hearing loss. 

Conclusion 

In case a person is sensing reduced hearing in one or both ears, he/she needs to seek medical advice. It may be a symptom of mixed hearing loss. Getting in touch with an experienced physician is the first step towards that.
