In history books, the devices used to aid hearing have been there or centuries. Some of the early versions include ear horns and even ear trumpets which were basically funnel shaped and work by concentrating sound waves and guiding the same to the ear. With the modern technological advancement, the devices used for this purpose are now much smaller and very effective. The commonly used electronic devices for this purpose include the bone-anchored aids, the cochlear implants, disposable and 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 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.
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.
