A system was made to process the data of patients with hard of hearing, and to make statistical process by combining the multi-card selector and electronic calculator which is capable of program calculation. This is to report the fact that the system was useful to obtain correlations between certain diseases and the results of hearing test.
This system is characterized as the followings:
1) Operation is easy and requires no specialist.
2) Many ready-made programs are available for calculator.
3) Program can be altered easily according to the purpose of study.
4) Low price of apparatus (lower than ¥2, 000, 000).
5) By using the system, studies on various objects and methods can be performed simultaneously and easily.
A disadvantage of this system is that the complicated numeral data must be turned to simple ones (1 or 2 fingers) to make the process easier.
