The earliest electronic hearing aids were rather crude devices. While it was a real breakthrough technology at the time it presented quite a few challenges for both the engineers and the users. When electronic devices became really popular in CA, it presented a lot of interface challenges for hearing aids and more than anything the interaction between the hearing devices with other electronics caused the problems. More than anything it was telephones and that presented some of the biggest problems. In normal circumstances it could amplify sounds but over the phone it often required some additional adjustment and/or adapters.
One of the main advances in hearing aid technology is the latest digital technologies. Not only are these devices much smaller, but they are much more sophisticated and almost robotic. Sounds are more natural, clearer and the dives themselves can be programmed to suit an individual. Because its digital it offers a number of opportunities to work with some of the latest technologies of some other devices.
All Hearing Aids are designed to help the person with some hearing loss to have greatly improved hearing. There are two types analogue or digital, depending on how the sound is amplified. Digital are similar to analogue that they both have a microphone which collects the sound waves in the air and converts them into electrical energy. This electrical energy is amplified and fed into a small speaker which converts the amplified electrical energy back into sound waves to feed into the ear channel to energize the ear drum.
Digital aids differ from analogue in that the amplifying part of the process is carried out digitally, which converts it into ‘bits’ of data by a tiny computer type chip in the hearing aid. These ‘bits’ which represent the sound are then analyzed and manipulated by a process called Digital Signal Processing. Software is then used to carry out precise changes to the `bits` of information such as reducing the amplification of background noise. These electrical bits of information are then fed to a minute microphone and converted back into sound, which is fed into the ear channel to act on the eardrum.

Reasons of Hear Loss in Nelson California
Most hearing loss falls into one of two categories conductive or sensori-neural. Conductive hearing loss occurs when the sound waves cannot be conducted from the outer or middle ear into the inner ear. A blockage in the ear canal, a punctured eardrum, a middle-ear infection or any problem that would prevent the eardrum or ossicles from vibrating produces a conductive loss.
Sensori-neural hearing loss occurs either in the inner ear (the sensory part) or in the auditory nerve (the neural part). When sound reaches the inner ear but is not correctly perceived, or is correctly perceived but cannot reach the brain, the resulting loss is considered sensori-neural. Damage to the hairs or nerve cells in the cochlea or damage to the auditory nerve produces a sensori-neural loss. There are several factors that can clue you in. If your own voice sounds loud to you and other voices sound muffled, chances are your loss is conductive. Ringing in the ears, hearing better in noisy surroundings than in quiet surroundings, tolerating noises other people feel are too loud and speaking too softly for other people to hear are also characteristic of conductive loss.

A digital hearing aid is a kind of assistant listening device emerging in the market recently and it is the most advanced assistant listening device now. With a product like this, people can hear clearly and feel more comfortable. Actually, there are various models of this kind in the market with different features and additional functions. The following text will tell you the detailed information about digital hearing aid and tips to choose a suitable one.
Generally, there are two types of hearing aids in the market according to sound processing system: analog one and digital one. Between this two types, digital one is the latest one which is smaller, lighter, and even invisible. At the same time, it has four main kinds of hearing aids according to the appearance: BTE (behind the ear), ITE (in the ear), and CIC (completely in the canal) digital hearing aids and open ear hearing aid.
In The Canal. An entire subset of devices sits in the ear canal. Receiver-in-canal models come in discreet designs and are easy to adjust. They work well for all levels of hearing loss, from mild to severe. Available in a variety of colors, they provide excellent sound clarity. Completely-in-canal models are virtually undetectable. They work well for mild to moderate hearing loss and provide phenomenal sound quality. Standard in-canal models are visible but can be accessed easily. They also deliver top quality sound, including clear voices that stand out in almost any environment.
The third types of hearing aids are the ITE devices. ITC’s are customized devices specially manufactured to suite the exact size and shape of the user’s ear canal. A very recent type ITC is a CIC usually known as completely in canal device. These hearing instruments are apparently hidden inside the ear canal. These types of hearing aids are not however prescribed for very serious hearing impairment, because though, these devices are aesthetically quite preferable but owing to their small size their amplification power is not very high. ITC’s are also not advisable for children. There are many types of hearing aids tailored specifically for your needs to enable you to hear the sounds you would never like to miss no matter your hearing loss is severe or mild.
Behind The Ear. Hearing aids that are worn behind the ear work best for moderate to severe auditory impairment. They come in discreet designs that tuck behind the ear for privacy. Models have buttons or dials that are easy to use, and a variety of colors are available to suit your preference. This style is recognized for comfort and high performance.
The BTE are the oldest types of the hearing aids. The BTE as the name indicates are employed behind the ear with a wire that connects to an ear mold, which is worn inside the outer part of the ear. A hard plastic case embodies the electronic equipment, and sound is transmitted through the wire into the ear mold. BTE is usually prescribed for hearing impaired people of all ages, and can be used at all levels of hearing loss; from minor hearing defect to very serious hearing losses.
Another sort of BTE has been introduced quite recently, usually known as the open fit hearing aid. In these types of hearing aids, the plastic case still rests behind the ear; but instead of an ear mold like in older types of BTE, a small tubule is introduced inside the ear canal. The open fit aids have been red by many users as it is observed that open fit aids have bettered considerably the sound quality.
In-The-Ear (ITE). These hearing aids are not as big as the BTH hearing aids and sit just inside the ear. These hearing aids do not have a large section that sits behind the ear and do not have a tube that runs to the ear. The ITE hearing aids are very comfortable and are also not very expensive (more expensive than BTH) which makes them a great choice if you are looking for something relatively inexpensive and of a smallish nature.
Completely-In-Canal (CIC). Completely in canal units are the smallest hearing aids to ever be made, they are so small and site so far down your ear that they require a string to remove them. These hearing aids do not have manual controls since they are so small and can be difficult to remove if you have not been shown how. However, the good thing about these hearing aids is that they are totally unnoticeable and have a good sound, they are also the most expensive because they are so small.
How to Protect your Hearing Aids in Nelson California
Avoid moisture. Moisture build up is one of the main reasons for hearing aid dysfunction. Moisture sources include: exposure to water and other liquids, heavy perspiration, and high humidity. If possible, remove your aids during activities that may cause excessive sweating. Do not shower, bathe, or swim while wearing your hearing instruments. In months of high humidity or in humid locations, consider using a dehumidifier nightly to prevent moisture buildup.
Avoid high temperatures. Excessive heat will damage a hearing aids very quickly. Do not leave your aids in a car, especially in hot locations or summer months. Never leave a hearing instrument to sit in direct sunlight. Do not heat an aid in an oven or microwave. If your hearing instrument becomes wet and needs to dry, remove the battery and leave the battery door open. Place the aid in a dehumidifier or even in dry uncooked rice, and allow to dry overnight.
Use them properly. Just like any other device, how you use the them greatly affects how long they last. The first step to ensuring that it lasts for a long time is ensuring that they are professionally installed. This calls for you to work with a certified and experienced audiologist who will diagnose your condition and help you in installing the right one. The doctor will also give you tips on how to wear the them so that they don’t develop any problem. In case of discomfort, chances are that you aren’t using the aids the way that you should. If you are having trouble with your hearing aid, contact a professional to take a look at them.
Maintenance. Another way of taking good care of it is cleaning them regularly. Hearing aids are prone to ear wax clogging. When they clog they aren’t effective enough. Dirty ones also tend to accumulate a lot of harmful bacteria thus putting your ear at danger. To get rid of bacteria and wax, you should regularly clean them. The cool thing is that it’s easy to clean as all you need to do is use a soft piece of cloth to wipe.
