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.
In their basic forms, they have component such as a microphone, circuitry, a receiver also called a speaker, a signal conditioning and a replaceable battery. The sound conversion of sound waves to electric signals takes place in microphone. The signals are conditioned and reconditioned through either amplification or equalization. The signals are then converted back to sound waves by the receiver.
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.
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.
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.
