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.
Currently, there are several rechargeable versions in market. They are slightly difference in terms of devices and functionality. The most common ones today are the ones placed in the ear, in ear canal and ones designed for behind the ear. The behind the year versions are normally a little more expensive as compared to other versions since they require custom fittings in order to fit inside ears.
The models for ear canals too need to be fitted since the design is that they remain invisible. This is achieved by placing them deeper in the ear. The solution often lies in custom fitting. There is however the benefit of more natural sound experience which results from inner location and venting. The models in this category can be the extended wear that can stay in for up to three months and the open fit model which will comfortably fit behind the ear and allow for an open canal as a result.
The rechargeable hearing aid differs from the disposable version in that the battery is replaced when it run out unlike the disposable one where a new one has to be bought altogether. They are meant to be wireless and thus the user can program and set them through remote devices to the specification required.
The primary objective of these devices, just like their disposable counterparts, is to assist those with hearing loss problems. They make sounds that are more accessible for the wearers. The greatest benefit of these devices is convenience. There is no need of buying a new one but instead just replace the battery and you are good to go. They may not however be available for placement very deep into the ear as this does not permit frequent removal.
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.
