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.
The versions present in the market today shows just how technology has changed the whole field resulting to better solutions. There are those to be place inside the ear, others for behind the ear and some for the ear canal. The ones targeting to be placed behind the year will naturally require custom fitting and as such with influence costs upwards.
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.
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.
The primary objective of these devices, just like their disposable counterparts, is to assist those with hearing loss problems. They make sounds that are more accessible for the wearers. The greatest benefit of these devices is convenience. There is no need of buying a new one but instead just replace the battery and you are good to go. They may not however be available for placement very deep into the ear as this does not permit frequent removal.
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.
