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.
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 canal fitting on the other hands are meant to be invisible which requires placement deeper in the canal. As such, you expect custom fittings given that the size of canal varies by great margins from one person to the next. They are however comes with more natural sound experience, largely attributed to their venting and deeper location. You can find two types of the ear canal models. These are open fit model and extended wear model. The extended wear models, as the name suggests, are designed to stay in the canal for between one to three months. Open fit option fits behind the ear which gives and open air canal.
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.
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.
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.
