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

SSHL is not like any other normal hear-loss trouble. Rather it is quite a severe condition. Sudden deafness can occur at any time due to several reasons. This trouble does not affect both the ears rather only one specific ear is usually affected, and thus this is one of the prominent signs that can help the doctors to understand that SSHL has occurred. 


What are the leading causes of this hearing loss?

    Head injury: If you have faced any severe kind of head injury ever, then it might bring SSHL. This is why you are suggested to get necessary treatment on time so that this kind of hearing loss can be avoided.
    Loud-noise exposure: If your ears are exposed to louder noises or sounds in a consistent manner, then there is a greater possibility of the occurrence of this hearing loss. Thus, you should stay away from unwanted noises. 
    Ageing: With the increase in age, hearing power slowly decreases. However, if you take proper precautions from the very beginning, then SSHL can be definitely avoided. 
    Blood-circulation troubles: Interrupted blood-circulation creates different physical troubles out of which hearing loos is one of the most prominent one. And if timely treatment is not provided, then it might get converted into SSHL. 
    Ototoxic medication: This kind of medication should not be continued for long without doctor's prescription otherwise SSHL might occur. 
    Lyme disease: This is a kind of disease, which occurs due to tick bites and this is pretty infectious in nature. Apart from that, this disease is now considered as one of the main sources of SSHL. 

How to evaluate this hearing loss? 

    History analysis: The history of the patient needs to be known first otherwise SSHL cannot be perfectly treated. If the history shows that the patient already has an existing trouble of ear loss for which SSHL has been proven, then in accordance with the same the treatment can be prescribed. 
    Laboratory and imaging: Laboratory analysis is one of the main methods for evaluating SSHL and necessary images of the ears boost the potentiality and importance of this kind of analysis to a great extent. 
    Quick evaluation: This kind of medical evaluation is mainly made on the basis of the symptoms. The doctors often follow the signs thoroughly in order to determine as to whether the patients have SSHL or not. This evaluation is highly supported by different medical tests that are prescribed by the doctor.

Sudden Sensorineural Hearing Loss: Causes and Evaluation

Hearing is one of the five senses that you or anyone else relies on for communication and a whole host of other things. Among the five senses, touch, smell, taste, hearing and sight, it is often hearing, which is the most easily affected. You don't have to be a senior citizen to experience hearing loss as it is quite common among younger people as well. This problem is also getting widespread with each passing day.

Before coping with hearing loss, the first job is to detect it
If you have a hunch that you or any of your loved ones is suffering from hearing loss, it is important that you get it diagnosed. Some of the common symptoms of hearing loss will be:

Hearing difficulties while talking to someone over the phone
Straining to hear conversations with family members or friends in household situations 
People usually need to repeat what they talk to you with a louder voice
You often hear complaints that you keep the TV too loud.
In crowded situations, such as family gatherings or a restaurant, you have problems listening to people.
Although this condition tends to affect senior citizens, an increasing trend shows younger people i.e. people mostly in their 40 and 50s and even younger than that suffer from this condition.

How to deal with hearing loss?
Some of the options to deal with hearing loss are mentioned below.

Once diagnosed with hearing problems, change your ways of communication: If you or your loved ones have been diagnosed with hearing problems, it is important that both adjust your ways to deal with the problem. Rather than getting angry at the other for not being able to communicate effectively, develop and strategize ways to make communication less problematic and erratic.
Cochlear implants: This is a newer technology, which has gained popularity in the past decade or so. These are directly implanted into the inner ear and are designed to bypass the damaged areas of the ear and directly stimulate the auditory nerve. These have become very popular, although, are not a replacement of natural hearing. It is only prescribed for people who have severe hearing loss or are deaf.
Hearing aids: Although selecting a hearing aid is difficult as the patient needs to be comfortable, once selected it is one of the best solutions for the hearing impaired. The functionality of these devices can be extended with the hearing assistive technology or HAT devices that can focus the audio waves depending on the situations and give a more tailored approach for every individual's needs.

Coping with Hearing Loss

You should consider undertaking a cochlear implant in case you are experiencing hearing loss or are turning deaf. This is a small device that gets planted in your ear through a surgical procedure. It sends impulses to your auditory nerves directly, as a result of which sound signals get carried to your brain. Cochlear implants may not make you hear normally again, but help you with different sounds, and in the recognition of the different sounds around you like alarms, telephones, and door bells.

How it works?

A cochlear implant is fit for children and adults who suffer from the sensorineural hearing loss. This condition damages the tiny hair cells in your inner ear, which is called the cochlea. Hearing becomes impaired when these get damaged.
The device consists of two specific parts. The first part or the receiver-stimulator is placed under your skin via a surgical procedure. The other part of the device is the speech processor. It has to be worn around your neck in the form of a hearing aid.
The external device is, however, larger in size than a usual hearing aid. The receiver gets placed under your skin, behind the ear via a small incision. It is connected to electrodes.
This is inserted into the cochlea of your inner ear. The surgery requires a few hours to be undertaken successfully.
The speech processor has to be placed two weeks after the surgery is undertaken. The processor can be connected to the microphone, and this can be worn around the ear.
You can wear it on any other part of your body, based on your lifestyle and age.
Benefits of cochlear implant
The major benefits of a cochlear implant are as follows:

You might be able to hear speech almost normally.
You will be able to understand speech better, and will not have to depend on lip reading.
It will be much easier and simpler for you to listen to the television and talk over the phone.
You will be able to listen to music better.
You may also be able to pick up various sounds around you that include soft, medium, and loud sounds.
You will be able to control your own voice better. This makes other people understand you better.
If you are suffering from severe hearing loss, a cochlear implant may be able to change your life for the better. However, the results are not the same for all, and vary among people. It is possible for some people to benefit more from such an implant than others. 

Cochlear Implants - 6 Benefits You Must Know!

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

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.
