Historically, several techniques have been used to solve the problem of hearing loss. In early times, funnel shaped cones or trumpets were used to try solving this problem by collecting sound energy and then guiding the same into the ear. Today, there are a number of devices used for this purpose, both electronic and non-electronic. Among the electroacoustic devices used currently are the bone-anchored aids, cochlear implants, disposable and the rechargeable hearing aid.
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.
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 canals too need to be fitted since the design is that they remain invisible. This is achieved by placing them deeper in the ear. The solution often lies in custom fitting. There is however the benefit of more natural sound experience which results from inner location and venting. The models in this category can be the extended wear that can stay in for up to three months and the open fit model which will comfortably fit behind the ear and allow for an open canal as a result.
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.
