description: The object of the study is bit error in data transmission through acoustic communication channel. The purpose of the work is to explore the possibility of transmitting digital data at a given rate through acoustic communication channels of different environments. The first chapter of the work describes general principles of communication systems construction and existing solutions in the field of data transmission over sound. Also, general information about the sound field is given. The second chapter of the work presents the result of the development of a mock-up of the transceiver and receiver system for data exchange over the sound channel. The system is realized in MATLAB. Brief theoretical explanations are given for each block. In-depth description is beyond the scope of the bachelors graduate qualification work. The third chapter of the work contains results of exploring dependencies of bit error rate on the system parameters during transmission in different environments. Open educational resources and programs of information search and analysis were used. MATLAB software was used.
