| Abstract: | In the wild used in open plan offices, due to itS structure, there are many disadvantages, such as the distractions,of intruding conversation, noise and poor speech privacy. According to sound masking theory and recursion theory of pseudorandom signal, we have created a new way to develop masking sound source and its system, which takes advantage of microcontroller and micro-electionic technology. The results have showed that the system can eliminate the noise and get a good speech privacy. |
