Hearing aids are devices which help in the sound amplification for a person who is disabled with hearing loss or is partially deaf. There are various different kinds of hearing aids. Invisible hearing aids are devices which can’t be seen because of the way they are placed in the ears. These are known as in canal hearing aids or IIC and leave no or little trace of them being visible from outside. The reason is that they fit deeper inside the ear bowl than the other types of hearing aids and are not visible when directly looking inside the ear. A very comfortable and exact fit is achieved because the hearing aids are custom made to fit an individual ear after taking a mould. Invisible hearing aids type use venting and their deep placement inside of the ear provides a more natural hearing experience to the user.
In the other types of hearing aids the majority of the ear is blocked by the plastic which is used to make the hearing aids. But with invisible hearing aids this is not a problem. Due to this the sound travels more naturally through the shape of the ear and also down the ear canal as it would do with natural hearing. In many cases depending on the size some models allow users to wear a mobile phone which the user can use to control the memory and volume settings. The invisible hearing aids do not need to be taken out to do this. Invisible hearing aids are suitable for users up to the middle age but are not suitable for elderly people.
Thus invisible hearing aids help people with disability and those who need help with hearing loss. Scientists and engineers are researching and developing special hearing aid devices which can be used to make life better for such individuals.
