Hearing aid

- When the material is supplemented, I will clean it up and repost it. -

A typical hearing aid can't be distinguished by mixing sounds in noisy places or in a multi-person voice environment.

This is due to the limited performance of the amplifier inside the hearing aid. This may be due to the lack of linearity of the amplifier, or because of transistor-specific characteristics.

By applying high-quality amplifier technology to these hearing aids, several sounds can be separated and listened well.
