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.
The basic components of a rechargeable hearing aid include a microphone, a receiver (speaker), signal conditioning and a battery that can be recharged. The microphone does the job of sound conversion to electric signals, which then undergoes some conditioning such as amplification or equalization. The receiver then converts the signals back to sound. All the components are 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 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.
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.
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.
There are several models differing in both the design and functionality and as such, the price range is quite wide. If you choose to search one over the internet, there are hundreds of options from different manufacturers to choose from. Other than just reading the information placed by the manufacturer, it is very important to read through the customer review information.
Currently, there are a number of organizations that assist people with this problem. They can avail a rechargeable hearing aid for free or at worst at a very encouraging discount. Be sure to take advantage of such chances or select a too quality type at good price.
