A rechargeable hearing aid remains one of the devices that have seen revolution. The early versions of hearing aids were simply funnel-shaped cones that could collect sound energy and guide them into the ear. These were referred to as ear horns and trumpets. Today, this is one of the electroacoustic devices in the market. There are other similar devices such as cochlear implants and bone-anchored aids.
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.
The versions present in the market today shows just how technology has changed the whole field resulting to better solutions. There are those to be place inside the ear, others for behind the ear and some for the ear canal. The ones targeting to be placed behind the year will naturally require custom fitting and as such with influence costs upwards.
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.
Unlike the disposable versions which become useless ones the power run out, the rechargeable hearing aid is a better alternative. The design therefore allows for removal and replacement of the battery. They are normally wireless and as such, programming and reprogramming can be achieved by a remote control for adjustment of settings.
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.
When it comes to prices, there is a very big variation. You can go through the ones available online and choose the one that match you budget and meet your preference. There are a few publicly funded health projects targeting to assist those in need. Through such organizations, you can get one for free or at least with a big discount.
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.
