Hearing aids are special devices that helps the hearing impaired persons to hear sounds and experience the goodness of a normal hearing sense.

There are big improvements when it comes to hearing aids, in which they are already more compatible and more comfortable to wear compared to those which are designed at its first discovery.

1. Behind-the-Ear – the most common type,  hooked up over our ear and the ear piece itself is placed on the outer portion of the ear. This device is suitable for any age, cosidered as the best ear trumpet today when it comes to the power of amplification it transmits to the ear.

2. Completely in the Canal – goes completely inside the canal making it the least visible out of all the best deaf aid available today. This is not advisable for those who have severe hear loss. Uses only small batteries so we cannot use this for longer periods at a time.

3.In-the-Ear – made of hard plastic, much like the other deaf aid and this one fits perfectly in the outer ear. It is small in size which makes it less visible. This is one of the best deaf aid for those who work on the telephone all day . The device can transmit sound through a special feature called the telecoil.

4.In-the-Canal -  customized to fit inside the person’s ear canal, providing more comfort as it is molded just to the right size and shape of each person’s ear canal.

Sounds of different pitch and volume are being transmitted from our ears to the auditory canal by nerves which is interpreted by the brain. This is called the hearing process. Today the leadind disability in the world is hearing loss. There are many factors that leads to this disability. Heredity, aging, environmental factors, diseases, and loud noises.

The fact of the matter is that hearing loss is more prevalent in men than in women. The sad news is that in teens and young children the incidence rate of hearing loss is about 15 in every 1000. Hearing impairment in individuals who are aged 80 and above has reached an alarming 90 percent.

Sound characterization is in terms of frequency and intensity. The unit of measurement in fequency is expressed in Hertz while in intensity it is expressed in Decibels. The normal range of frequency is between 20-20,000 Hertz but in intensity the normal range is from 0-140 Db. Every word or sound that we make have a different frequency and intensity which the brain interprets as either language, noise, music, and the like.

The types of hearing loss is classified as conductive or sensorinueral. Inner ear infections, accumulation of fluid in the middle ear, excessive wax, damage to the eardrum by infection or an injury, or otosclerosis are the more common causes of a conductive hearing loss and this is usually temporary. The more permanent hearing loss is sensorineural hearing loss. Age-related hearing loss, injury to the inner ear hair cells as a result of trauma or noise, abnormal pressure in the inner ear, stroke, benign lesions, and brain tumors are among the common causes of this hearing loss.

The 4 Types Of Hearing Aids

1. The Behind the Ear- usually the least expensive of all of the hearing aid model types. A bit larger compared to the other types, fitting in right directly behind your ear.

2. In The Ear- one of the most popular types. These fit directly in the ear.

3. In Ear Canal- one of the more expensive types of hearing aids, fitting further down into the ear and are much less noticeable than the behind the ear or in the ear models.

4. Completely In The Ear Canal- hearing aid innovation can never be complete without mentioning these invisible hearing aids. Considered invisible because they are almost completely unnoticeable, typically given to people with mild to moderate hearing loss. These types requires fitting.

The Top 4 Companies

1. Siemens- a company that had been producing hearing aids for over 125 years. Their hearing aids always come with a 2 year warranty.

2. Beltone- with over 1400 locations nationwide and boasts a strong reputation as a high quality hearing aid manufacturer.

3. Starkey- they are considered as the world’s largest manufacturer of hearing aids. They had been known to be the first to provide a warranty for their products as well as the first company to offer a free trial.

4. Phonak- a Swiss company that features their product worldwide, offering their customers a wide selection of hearing aids and hearing devices to fit any situation at all times.

There are a lot of things that you need to consider when buying a hearing aid whether you are a first timer or not. Some would think that having a very expensive aid would really be effective for them but most of the time you need to have your status checked first by an expert for you to fully use the hearing aid in a more convenient and useful way. The following are the things you need to consider on buying one for yourself or even for other people:

1) Self Prescribing – When it comes to choosing the right hearing instrument, listen to your hearing professional and not just any people. Hearing specialists have the training and the education that make them uniquely qualified to help you with your hearing.

2) Giving up – Being fit for hearing devices is not as easy as being fit for a pair of shoes. It can often take several follow-up visits before the programming and physical fit of the hearing aids are correct. Always buy hearing aids with a trial period. Not all the time it will fit you quickly so you need to find ways to have it customized for you.

3) Buying Hearing Aids in a Physician’s Office – A physician’s office sounds like the best place to buy, after all it is a doctor’s office.

4) Putting Off Buying Hearing Aids – People often wait until their hearing loss is worse to get the help they need. The longer you wait to get help, the harder it is to adapt. This is because your brain becomes accustomed to not hearing and ” forgets ” how things are supposed to sound. When you start wearing hearing aids, things often sound different then you remember and you have to retrain your brain. The worse your hearing loss becomes, the harder this retraining is to accomplish.

A hearing aid is an electroacoustic body worn apparatus which typically fits in or behind the wearer’s ear, and is designed to amplify and modulate sound for the wearer. Earlier devices, known as an “ear trumpet” or “ear horn“, were passive funnel-like amplification cones designed to gather sound energy and direct it into the ear canal. Similar devices include the bone anchored hearing aid, and cochlear implant.
There are several common problems for first time hearing aid users that can be corrected if handled appropriately:

1. Unrealistic expectations. Many people are fitted for a hearing aid and assume that they will now have perfect hearing and perfect clarity immediately.

2. Trying too much too soon. Popping in a hearing aid on the first day and expecting to go to a baseball game or theater means the wearer is doomed to disappointment. The sudden increase in hearing a user experiences with hearing aids will be overwhelming.

3. Too much recruitment. Recruitment is a technical term referring to the way some sounds seem over-amplified when someone is wearing a hearing aid. This usually happens because there is a limited range in which a hearing aid can work. The aid has to amplify all sounds, but some don’t need to be amplified as loud as others, and the resulting distortion translates as recruitment.

4. Neglecting hearing aid features. Anyone with hearing aids that utilize the latest features, such as directional microphones or noise cancellation technology, should be sure they understand how to adjust these features before they leave their audiologist’s office. If they get home and discover they aren’t sure, it’s essential to schedule a follow-up visit.

1. Due to some medications- some antibiotics and drugs for treating malaria that can cause dome hearing damage to the cochlea.
2. Diseases- chronic ear infections or childhood diseases auch as measles and mumps can lead to hearing loss.
3. Wax buildup- overgrowth of ear wax can lead to hearing loss. There are irrigation techniques that can be done to relieve this type of hearing impairment.
4. Ear or head injuries- some hearing impairments comes from direct damage to the head or ear resulting to hearing loss.
5. Noise on working place or being around loud noises for an extended period of time- can damage hearing, whether machinery or music, gunshots or jets. The more ears are exposed to noise, the more profound the hearing loss can be.

Some hearing loss development can be a result of pregnancy and birth.

1. Deafness- can be inherited from the parents, higher likelihood of hearing loss if one or both parents have a hearing impairment.
2. Jaundice- can lead to a damaged of hearing nerve for newborns. This raises the risk of hearing loss.
3. Medication- some antibiotics and other medicines given to the mother during her pregnancy can lead to extended hearing loss risk.
4. Infections- such as rubella, can give way to hearing loss in the pregnant woman.
5. Premature births- have a high risk of hearing loss in the child.
6. Lack of oxygen- can result in hearing impairment as well if the baby lacks oxygen.

1. Body hearing aid- for mild to profound deafness.
Adv- prevents acoustic feedback through seperation of reciever and microphone for high amplification.
Disadv-  bulky, requires long wire which may be cosmetically displeasing.

2. Behind the ear hearing aid- for mild to profound deafness.
Adv- larger size lets the use of larger components for more power and features, and versatile due to size and it no longer needs long wires.
Disadv- large size is the only disadvantage.

3. In the ear hearing aid- for mild to moderately severe deafness.
Adv- custom fit to contour of ear, needs no tubes or cords and a miniature microphone located in the ear to look more natural and cosmetically more apealing due to easy concealment.
Disadv- smaller size limits the output. Those who have arthritis who cannot perform tasks requiring manual dexterity may have difficulty with the small size of aid and battery.

4. In the canal hearing aid- for mild to moderately severe deafness.
Adv- the same advantage as of in the ear hearing aid. It is even less visible and more cosmetically pleasing.
Disadv- smaller than the in the ear hearing aid requires good manual dexterity.

Hearing aids should be generally cared carefully. The patient must know how to take care of it and what to do if it fails. They must also have spare parts readily available.

Common medical problems among hearing aid users are otitis externa and pressure ulcers in the external auditory canal or meatus.

Mumbling- listening to a conversation but cannot quite make out what is being said, thinking that they are mumbling. Peoples voice has not changed it may be your hearing.

Repeating words- continually asking people what they are saying, it is a good indication that you are experiencing hearing loss. Telling people to repeat themselves is a sure sign of hearing loss if it is used every time others talk and you just do not understand what they are saying.

Getting the story straight-  it is quite likely that you will misinterpret what other people are telling you, getting the story mixed up and relay the wrong information to someone else because you are not hearing it.

Being in crowds- while you are in crowds, everything becomes a jumble of noises with no clarity, finding it difficult to clarify sounds and really not be able to distinguish anything.

Choosing which ear- favoring one ear over the other when you are listening to sound. This can easily be detected when you talk on a phone. You will find yourself placing the receiver on the ear that produces better sound.

Radio or TV- how loud you have the radio or TV it is a good indication that you may have some hearing loss. The sound may sound normal while others in the room cannot hear what is being said due to it being so loud.
