A cochlear implant is an electronic device that is used to restore hearing ability in people who suffer from hearing loss due to inner ear damage. Unlike hearing aids which amplify sounds so people with hearing loss are better able to perceive them, cochlear implants directly transmit electronic sound signals to the auditory nerve. They work by compensating for damaged cochlea, the part of inner ear that converts sound waves into neural impulses which are perceived by the brain. 

A child who cannot hear will also never be able to speak. 
Inability to hear and speak puts a person at disadvantage in society. 
Simple tasks like talking on the phone which we take for granted become impossible. 
Conventional methods of learning like attending a classroom lecture become impossible. 
Brain development and intelligence is closely linked to development of speech and language. 
Inability of parents to communicate with child leads to emotional distancing. 
Integrating a hearing disabled person in to society becomes a frustrating experience for all involved. 
Cost of integration per capita in much higher when compared to cost of Cochlear Implant. 
Children with Cochlear Implants are fully integrated in society with normal hearing & speech. 
Children with Cochlear Implants can attend regular schools & colleges 
Early identification of hearing impairment gives children a better chance of developing speech and language skills, and of making the most of social and emotional interaction from an early age. 
Cochlear implants offer a multitude of benefits to people experiencing hearing loss, especially infants and children with severe hearing loss who are just starting to process language and speech. Some of these benefits are: 

Hearing and communication   Cochlear implants improve hearing significantly, especially to a level where normal communication can be restored. It enhances the person s ability to hear speech without relying on visual cues such as lip reading or hand signs. It makes telephonic conversation a lot easier. Cochlear implants also help people regulate their own voice and volume so that it is easier for others to understand them. 
Quality of life - It can help people with hearing loss listen to and enjoy music and also watch television with sounds. It helps people listen to sounds in a noisy environment and differentiate soft sounds from loud ones. 
Safety   Cochlear implants enhance the individual s safety as it allows the person to be able to hear warning sounds like honking cars or ambulance sirens. This will allow people to navigate public spaces in a much safer way. 
Society - For children with hearing loss, cochlear implants can help them adjust a lot better to regular schools instead of requiring special institutions. 
Brain development - It can help infants with cochlear damage develop their speech recognition and speaking skills much faster. 
Cochlear implants 

Only device of its kind that can restore a special sense.
Consists of 2 parts-
One part is surgically implanted in the body 
Second part is worn behind the ear and communicates with internal part using wireless signals 
Persons of any age can get a cochlear implant, from less than one year old children to 90 year old persons have received implants all around the world. 
Cochlear implants can be done for partial hearing loss also, know as Hybrid implant that preserves the residual natural hearing and augments hearing only in certain sound frequencies in which hearing loss is present. 
Are being used for indications other than hearing loss also like Tinnitus. 
Surgery is a day care procedure for most patients. 
Consult a doctor to get a clear assessment of whether you would be an eligible candidate for a cochlear implant and what to expect from the procedure.

Cochlear Implant - The Many Benefits Of 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.

BAHA Implant and Cochlear Implant Surgery

Here are 6 signs to watch out for that could indicate 'You need to get your Ears tested':

1. Your TV is blaring: Do you often find people around you shouting above the TV sound complaining that it's too loud? When you find it hard to hear the TV at the average volume and find yourself turning up the sound, this could signify a hearing loss. Doctors are seeing a growing number of patients visiting them after prolonged exposure to loud music and sounds.

2. You find it hard to hear phone conversations: Do you find yourself asking the person on the other end of the phone line to 'repeat' themselves, or find yourself pressing the phone instrument right into your ear? If you are trying so hard to hear, you might find yourself missing out on bits of the conversation as focussing to clearly hear the conversation is exhausting work. Getting a hearing test might be a good option if this sounds like you.

3. You have trouble hearing in noisy environments: When you are out dining with friends or family at a busy restaurant or accompanying a friend shopping in a busy street, all that background noise makes it difficult to hear what the people are saying. People with hearing loss often have problems masking out background noise.

4. Family members telling 'you're going deaf'?: Trust the views of the people closest to you, they never lie about your health. Family members often are the first to sense signs of hearing loss as they find themselves repeating things to you or calling out louder to get your 'attention'.

5. You find yourself staying away from social occasions, family gatherings or avoid being the first to start conversations

6. You find yourself leaning closer to people to follow the conversation or staring at their lips trying to lip-read what's being said.

6 Signs you Need a Hearing Test

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?

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

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.
