Methods of Digital-To-Analog Conversion for Reproduction of Sound Waves

In this paper we are considering a method of digital-to-analog conversion with which it is possible to implement the transfer of sound information using air flows generated by fans. The architecture of the software-hardware complex with which this is done and the algorithm with all stages of data preparation, processing and transmission are also considered. Experiments conducted to verify the effectiveness of using this method in real life are also described. People participated in the experiment, who needed to identify the class of sound that is reproduced by means of the created complex. For this, the combination of air flows for each class must be previously learned by a person. Also, a separate stage of experiments with sounds typical of wartime was conducted. The results were formed, in which it was found that certain combinations of the duration of sounds and their count can indeed be correctly identified by a person.
