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.

Mixed Hearing Loss - How To Treat It?

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 Meniere s Disease?
Meniere's Disease is a disorder that basically affects the sense of balance and hearing of the patient. This condition takes place in the inner ear and it may cause problems like vertigo, where patients experience a spinning sensation and a ringing sound as well. This is a chronic disorder, which requires a number of lifestyle changes so that it can be managed and treated without becoming a debilitating problem.

Read on to know more about the symptoms and causes of the condition.

Symptoms: The various signs and symptoms of this disease include a feeling of fullness in the ear, which has been affected by the condition. Also, most patients have a spinning sensation and a ringing sound in the affected ear. Nausea and vomiting may also be caused by this condition, along with sweating and loss of balance. It is also normal to feel uncoordinated when you are suffering from this condition.

Secondary Symptoms: This condition may also cause many other complications, which are known as secondary symptoms. These include anxiety, depression and stress. This usually happens due to the problems in the ear and even the problem of vertigo. This may cause problems for people who climb heights or ladders for their work or even for other recreational causes. The constant sense of dizziness and spinning may cause a person to become anxious and undertake stress when it comes to carrying out various kinds of functions in day to day living.

Causes:  There are various causes of this condition, even though many medical reports suggest that the exact cause has not really been understood so far. As any doctor will tell you, the in the inner ear there is a labyrinth which contains fluids. When there is a problem with the composition and level of these fluids, the patient may develop Meniere s Disease. This condition specifically affects the inner part of the ear. This part is made up of passages and a cavity as well as soft membrane like structures with hair like sensors. These sensors respond to the fluid s movement within the ear. When this fluid does not have the appropriate levels, it can lead to many complications like Meniere s Disease, which affect the nerve impulse that these sensors catch and transmit to the brain.
Stages: This disease progresses over a set of three stages. In the very first stage, the patient will experience much dizziness and nausea, before that progresses to the second stage. In this stage, the patient will have moderate to severe vertigo. This is also known as the middle stage. Finally, this may culminate into the third or late stage, which leads to more frequent episodes of vertigo. The hearing of the patient and the ringing sound in the ears will also get worse in this stage.

Meniere s Disease -  What are the Reasons Behind It 

A deaf child is the one who suffers from hearing loss. Children with deafness may also fail to develop speech. Such children might have no defect in their speech but they cannot speak anything. The main reason is deafness. They do not hear a speech, therefore, cannot develop it. Deafness may not be hereditary, but it occurs due to several other causes. 

The period of 5 years is crucial in a child s life. During this period, they develop their speech and language. Therefore, parents need to take the utmost care for the early identification of hearing loss and treat the child accordingly. 

Causes of Deafness in Children

There are several causes of deafness in children.

Otitis Media: In young children, if the eustachian tube is not fully formed, it forms fluid behind the eardrum. This fluid can get infected and affect the hearing. The fluid may not cause any pain or infection but still, it can harm and cause hearing loss even if it stays for a short time. 

Problems by Birth: Some children have hearing problems by birth. Sometimes, the problem lies in the genes. But, other times during pregnancy or prenatal care, the problem arises. If a mother, while pregnancy, has diabetes or preeclampsia, she is likely to deliver a deaf child. A prematurely born baby also has a high risk of deafness.

Illness or Injury: Some young children suffer hearing loss due to some injury in the ear or some other illness. Illness includes meningitis, measles, chickenpox, and flu. Head injury or listening to loud music for a long time can also be a reason.

Symptoms of a Deaf Child

A deaf child shows no reaction to the loud noises.

He/she doesn t respond to the voices.

The sound of the child is simple that taper off.

The child may pull or rub the ear several times, which is noticeable.

The child is continuously cranky for no particular reason.

He/she does not pay any attention when anyone is talking.

He/she has very little energy to do anything. 

He/she fails to understand the direction.

Often asks to raise the volume of TV or radio.

Have fever and ear pain.

Treatment of the Problem

Hearing loss affects a child s learning ability. So, the problem must be diagnosed and treated immediately. Here are some treatment approaches: 

Treatment for Otitis Media: The very first thing parents and doctors can do is watchful waiting because sometimes the problem cures itself. Some pediatricians might prescribe some antibiotics. If the problems continue, then the doctor will suggest getting an ear tube to the child that will allow the fluid to drain. For this, the child will have to visit an ENT doctor also called Otolaryngologist. 

Treatment for other causes: The child may use a hearing aid. Some can get cochlear implants. 

Conclusion
It is necessary for parents to accept the child with deformity and stay by his/her side. They must get themselves educated and communicate the problem with others to get help. It is essential to stay in touch with the child and take care of him.

Deaf Child - What Should You Know?

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!

Loss or impairment of hearing can happen due to a variety of causes and may be temporary or permanent in nature, depending on the type and severity of the condition. One of the most common causes of hearing impairment is age. The degeneration of one's vital organs and senses becomes a reality for many people as the advancement of age happens, and the delicate insides of the ears are no different. Noise pollution, injury to the ear drum or any other part of the ear, as well as the movement of particles inside are only a few of the many reasons for loss of hearing. One of the many ways of dealing with long term hearing impairment is by using a hearing aid. Read on to know how you can regain your hearing with hearing aids.

1. Long Forgotten Sound: A hearing aid will help you reacquaint yourself with long forgotten and subtle sounds that you may not have been able to hear for a long time. Many times, this kind of impairment also makes us forget to notice the fact that we do not hear so many normal sounds in our everyday lives - sounds that we probably did not notice even earlier. This may include the whirring of a fan, the whoosh of the air, the pitter patter of pets' feet and so much more. A hearing aid will help in bringing about an adjustment to these sounds that you will actually end up discovering again.

2. Technicalities: The hearing aid basically works by letting your hearing and ears readjust to the various volumes, intensity and vibrations that one feels when different sounds reach the ears. This helps in hearing better.

3. Amplification: A hearing aid is basically an electroacoustic device that fits in neatly behind your ear where it is tucked away from plain sight. This device helps in amplifying sounds so that you can catch them and hear them more clearly.

4. Modulation: The ENT specialist will usually prescribe a certain kind of hearing aid based on your individual condition in terms of volume, size, power and circulation. These factors help in modulating the sounds in a certain way so that they reach the nerve pathways from the inner ear and travel to the brain in a proper and effective way. This is usually done in a customised way to cater to the specific type and cause of your hearing loss.

Using a hearing aid is a matter of retraining your hearing rather than restoring it completely. These aids will be helpful in regaining a better sense of hearing within the condition you are going through, rather than reversing the condition completely.
