4233-A Hearing Aid as Assistive Technology

Let me introduce you a hearing aid as assistive technology. A hearing aid assists those with a hearing disability in catching what others say. It collects the sounds from the microphone and amplifies and emits the sounds on a speaker.

A hearing aid became popular in the 2000s. Formerly it has been an analog hearing aid. As a result, all sounds were amplified. But a digital hearing aid was invented. It amplifies human voice and can suppress noises by adjusting it.

A hearing aid has different shapes, in the ear, behind the ear, in the canal. A hearing aid in the ear becomes the mainstream now.
