In history books, the devices used to aid hearing have been there or centuries. Some of the early versions include ear horns and even ear trumpets which were basically funnel shaped and work by concentrating sound waves and guiding the same to the ear. With the modern technological advancement, the devices used for this purpose are now much smaller and very effective. The commonly used electronic devices for this purpose include the bone-anchored aids, the cochlear implants, disposable and rechargeable hearing aid.
Among several other components, the primary ones that you cannot miss in a functional rechargeable hearing aid are the microphone, a signal conditioning, a battery and a speaker which is the receiver. Initially, the microphone receives sound signals, convert them to electronic signals which are either amplified or equalized through the signal conditioning before passing the same to the receiver which convert it back to sound waves recognizable by the ear. It is all powered by the battery.
There are several versions in market today, all designed to meet different tastes and preferences. The ones you would commonly find are the models placed in the ear, ones for the ear behind and those to be placed inside ear canal. Since the ones for ear behind require some custom fittings, they are a little more expensive.
The ear canal models are designed to be invisible and as such, are placed deep inside the canals. They also requires custom fitting as due to difference in canal size from one person to the other. They are able to achieve more natural experience in the process of sound conversion largely contributed by venting and deep location in ear canal. They are further divided to extended wear and open fit model. The extended wear models can stay inside the canal for up to three months with no need for removal while the open fit version are known to comfortably fit behind the ears resulting to an open canal.
The major difference between rechargeable hearing aid and the disposable alternative is that former allows for battery replacement while the latter has to be disposed off when the power runs out. As such, it creates inconvenience. The programming has to be done through a remove devices given that the aid is not wired by any manner.
Given that the basic role is in improving sound reception to allow for interpretation, they are considered more convenient as compared to counterparts. You do not need to replace the old ones but instead buy the battery or charge them and continue enjoying hearing. The fact that they need to be removed and replaced often means that they are not designed for placement very deep into the ear.
Given the variety in designs and the number of brands, the prices range is very wide. It is important that you talk to your ear specialist for some suggestion. Further research can be done over the net which will turn very many options. If you are keen enough to go through the review information about the device you are about to buy, you will definitely find something that suit you.
There are some charitable organizations that offer a rechargeable hearing aid for free or with very good discounts in bid to help people with this kind of problem. You should take advantage of such organizations for better deals.
