HAHA3 Necessity

Most of the elderly are deaf and need to use hearing aids (more than 10% of the population).

Many hearing aid users do not use hearing aids because they are inconvenient or ineffective.

It is inconvenient to have to speak in a loud voice when talking to the elderly who are hard of hearing.

If there is noise around or if you are a little far from the person speaking, it is difficult to hear speech  even with a hearing aid.
