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.

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

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.

Regain Your Hearing With Hearing Aids

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.

Advantages Of A Hearing Aid!

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.
