One of the key abilities that should be learned by every student is mastering math skills. It is particularly difficult for blind students who have problems with access to information that is usually presented graphically for common pupils. In mathematics one such information is the presentation of graphs. However there are several drawing techniques for the blind, but they are expensive, and hard for common using. One way to solve this problem may be using a special sound representation of math graphics for the blind students. In this article, an approach allowing to provide making such presentation possible is presented. Briefly it is grounded on the conversion of graphic data of the math drawing to sound wave with proper assets.
