Abstract: Although the problem of hearing health has been paid much attention historically, it is estimated that 360 million people in the world suffering from some form of hearing loss (more than 5% of the global population). With the improvement of the living standard of the patients whom with sound barrier, and the demand of the modern hearing aids with smaller size (hidden), lower power and powerful function , all promote the technical progress of microelectronic packaging in the field of hearing aids. This paper well investigated the part of micro system technology used for modern hearing aids, such as MEMS microphone and speaker technology, DSP processor and memory chip, which are mainly used by IC stacked TSV technology, AiP technology which connect Bluetooth and hearing aids, etc. Some of micro-system technology have been maturely applied in miniaturized digital hearing aids, and some are still trying to be better to be adopted earlier. It can be said that the continuous development of digital hearing aids requires the continuous breakthrough of micro system technology, and the progress of new materials, new methods and new technology has been perfectly displayed on the micro digital hearing aids.
