<p> All hearing aids are made to perform a function, which is to improve the hearing of the suffering. </ P> r n <p> There are clear differences between analog and digital hearing aids <a> </ a> in the way they sound process for receiving amplified and sent to the ears. If analog is a very simple process. The sound is from a small parabolic microphone, converted into electrical signals which are then amplified before moving to a small speaker that converts electrical impulses back into sound considerably increased, which then impact on the eardrum. Digital AIDS have the same three stages, except that the amplification is performed digitally. This means that electrical impulses from the parabolic microphone are converted into data "bits" of a small computer chip. It 'can modify individual "bits", amplifying them or reduce them. This has the great advantage that the digital hearing may be imposed for loss of hearing exactly one individual patient. </ P> r n hearing <p> programming is also very different between analog and digital hearing aids Some of the latest analog can be programmed to emit sounds stronger or quieter. But a more limited scale in Digital aids. Thishearing loss in a wide range of frequencies. digital aid can be adjusted to eliminate background noise, allowing speech to be clearer when speaking in a crowded room. They are also built in digital circuits help to overcome the feedback, which is a shrill whistle. Protection from loud noise is often included </ p> r n <p> Some patients still prefer analogue hearing aids hearing impairment which can be seen on the forum .. different. The main reasons for providing a reference sound more natural, because amplify all sounds, even voices in the background of which we all now live in real <vita / p> r n <p> main advantage. similar aid, aid that is digital is much cheaper, so there's always a place for those who can not afford expensive Digital AIDS, but still want to improve hearing </. p>
