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

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?

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.

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 

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

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.
