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 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.
The major difference between rechargeable hearing aid and the disposable alternative is that former allows for battery replacement while the latter has to be disposed off when the power runs out. As such, it creates inconvenience. The programming has to be done through a remove devices given that the aid is not wired by any manner.
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.
In case you have some degree of hearing loss, you should try the rechargeable hearing aid. They come with great convenience. In addition to this, you have a number of models and versions to choose from. The manufacturers are also known to give discounts.
