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.
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.
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 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 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.
Normally, the function is to contribute in hearing by convert sound to easily accessible forms that can be collected by an ear that has reception problems. The wearer therefore stands to gain from better sound reception and interpretation. Due to the need for battery replacement that calls for frequent removals, they are not designed to be placed deep inside 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.
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.
